STRUCTURAL DESIGN FOR A LOW RISE OFFICE BUILDING Introduction As society advances, the built environment becomes an ever increasing component of everyday life. As a result, buildings and their design are becoming a very scientific field. Buildings can be as simple as four walls and a roof or as complicated as hundred story skyscrapers. Either way there is an art to the design and construction of buildings. Typically, people only see the outside of a building, or the skin. However, there is much more to a building then stone and windows. Buildings can be looked at much like living, breathing human beings. On the outside is a smooth skin, but under that skin are several different systems working together in perfect harmony to make life possible. The mechanical system of a building is like the respiratory system in a body. It is responsible for bringing in fresh air, along with conditioning each space to the right temperature. The electrical system is much like the nervous system in a body. It keeps the lights on and allows the building to function smoothly. The system this project focuses on is the structural system. The structural system of a building is exactly like the skeletal system in a body. The structural system is responsible for making the building stand and stay standing, even in extreme conditions.

STRUCTURAL DESIGN FOR A LOW RISE OFFICE BUILDING Body of Paper The overall goal of this project was to obtain a thorough understanding of structural system design and construction. This was accomplished by studying the four phases a structural project goes through; schematic design, design development, construction documents, and construction administration. After gaining a thorough understanding of these four phases the knowledge was applied to design an entire structural system for a four story office building located in Cheyenne, WY. This system was designed in accordance to all applicable codes. The project is discussed in depth within the background, research, applying what we learned and conclusion sections. Background This project was conducted in conjunction with the University of Wyoming Architectural Engineering Capstone class ARE 4720. This class is designed to give students real world experience in a classroom setting. Students are broken into teams of 2 to 3, and each team is required to design the entire structural system for a given building. The building for this year s capstone class was a new student center for the Laramie County Community College campus located in Cheyenne, Wyoming. The building will be used for various purposes and will contain offices, classrooms, and some student services. The capstone class is designed to be students final class prior to graduation. Therefore, students within the class have a good understanding of various structural systems. Students at this stage in their education also have a solid understanding of how buildings function, along with how the various systems within a building interact. The intent of the capstone class is to connect all the individual items students have learned. It is also designed to give students exposure to how an Page 4

actual construction project takes place. Students are not required to design an entire building but rather a component of that building as they would if they were working for an engineering firm. The class begins the semester by researching the construction process, where students gain a better understanding of how a project goes from conception to construction. After the initial research component, the class is divided into four phases as a real construction project would be, and each phase had a submittal associated with it. The remainder of this paper will follow the layout of the class. Research This project began with research on the construction process. We looked at how one person s idea becomes a finished project, paying special attention to the structural engineer s role within the overall project scope. Our findings are summarized in the engineer s timeline, phases of typical building project, and design process sections. Engineer s Timeline. Although a building may take a few years to complete, the structural engineer is not involved with the project the entire time. Depending on the complexity of the structural system, and whether it is a focal point or if it is hidden in the background, the structural engineer is only actively involved in about 25-50% of the entire project. Typically, they are subcontracted to the architect and do not come into the project until both the owner and the architect have a good understanding of the overall building design. This means the structural engineer typically has little say in the overall appearance of the project. Once the structural system erection is complete, the structural engineer is mostly done with the project. Occasionally the engineer will receive questions resulting from a design change or a potential issue, but the majority of the engineer s responsibility is complete at this point. Page 5

Phases of Typical Building Project. Our research revealed that there are four main phases a typical building project goes through. These phases are as follows: Schematic Design, Design Development, Construction Documents, and Construction Administration. The first three phases are all preconstruction. Only the fourth phase directly deals with the actual construction of the building and specifically the structural system. Each of the first three phases takes the design progressively more towards the final design. The design is done in a progressive manner so that a rough idea of the overall project costs can be estimated as early as possible. Other aspects of the project are continually undergoing revision as well, so it would not make sense to design the entire structural system at once only to have the building design change, which would require the system to be completely redesigned. Design Process. In addition to the four specific project phases described above, there is also a design process that is incorporated. The first step is to choose a structural system. This is perhaps the most important step in the entire process. Building size, use, and desired structural aesthetics are key factors in deciding which type of structural system to utilize. Once a structural system is chosen and the project location is known, the next step is to find all applicable codes. Different regions, states, and municipalities work under different codes. Following the correct codes is crucial for there are legal consequences if every code is not followed exactly as written. The third step is to calculate the loads. Buildings are exposed to two main types of loads, which are gravity and lateral loads. Gravity loads act in the vertical direction and are the result of the weight of the building and its contents. Lateral loads act in the horizontal direction and are the result of wind or seismic factors. During this stage the loads are very roughly calculated as the Page 6

actual building material and structural component weights are not yet known. These first three steps are all incorporated into the schematic design. Once a rough idea of the loading is known, member sizing can begin. This is typically contained within the design development phase. The construction document deals with precisely sizing each and every structural member along with all the connections between members. Once all the members are properly sized, the actual construction documents can be created. This is a set of blueprints with all the information required to build and erect the structural system. At this point the design process is complete. However, there is one more phase in the project. For the structural engineer, this phase is known as the construction administration phase. During this portion of the project the engineer is responsible for handling any questions that arise. These questions may be on constructability of the system or how to solve a problem that has arisen in the field. Applying What We Learned The second half of the class project is to actually apply not only what we learned in the initial research, but everything we have learned over our entire scholastic career. We applied the knowledge we have gained to design the entire structural system for the four story building that was previously mentioned. This process was broken into the four design phases previously introduced; schematic design, design development, construction documents, and construction administration, along with a section dedicated to calculations. Schematic Design. For our schematic design submittal, we were required to provide an executive summary of our intended structural system, state applicable building codes, give load & design criteria, and give details on our intended structural system. The first step in accomplishing these tasks was to select an appropriate structural system. There are countless systems that would Page 7

work in this situation, including mass timber, concrete, and reinforced masonry. My partner and I chose to use a structural system comprised of steel columns, girders, and beams, working in conjunction with a mixture of concrete shear walls and braced steel frames. This is a very common system for a building of this scale and usage. It is also a very popular system in this part of Wyoming. These two factors contribute to reducing the overall construction costs for the project. The first step was to determine the necessary codes. Since the building is located within the city limits of Cheyenne, the City Council of Cheyenne is the governing body. Therefore, the governing building code is the 2015 version of the International Building Code (IBC). ASCE 7-10 also governs and is closely tied to the IBC. The next step was to establish our load and design criteria. This includes factors such as our Flat Roof Snow Load, which we calculated to be 21 psf, our Basic Wind Speed, which was found to be 115 mph, and our seismic factors, which were found to be Ss = 0.155g and S1 = 0.036g. The seismic factors were found using the United States Geological Services website. The final step of the first phase was to discuss the details of the intended structural system. This included details on the foundation design based on the given geotechnical report, along with typical framing information. The lateral system and the interaction between its two different parts were also discussed. All the details of the schematic design submittal are located in Appendix A, which contains the entire submittal. Design Development. The second required submittal for this project was the design development or DD submittal. As discussed earlier, this submittal builds on where the SD submittal left off. The deliverables were an entire set of plans for the building, including a foundation plan. Also required were detail drawings showing specific areas of the buildings where the interaction between components may not have been entirely clear. The first step in Page 8

accomplishing the task for this submittal was to lay out the framing. This was challenging because the building was not square and each level changes slightly. The framing layout was further complicated by the way the architect laid out each floor. The building contains several slanting hallways and other challenging aspects that make column layout difficult. To complete the layout, the structural framing building was drawn in the 3D modeling program Revit. Gridlines were then added to create rectangular spaces that were easily broken into framing bays. Columns were then placed at most of the gridline intersection points. Unfortunately, due to the inconsistency of hallways and rooms from one floor to the next, there are a couple columns that are not continuous from the foundation to the roof. This resulted in the need for a transfer beam, a very deep steel member, to transfer the load from the upper column to the lower columns. Once a justifiable framing plan was created, rough member sizing could be done. In order to accomplish this, the tributary area for each member is calculated and the load acting on that area is found. This gives the total load acting on the member, which can then be used to determine how big the member needs to be in order to successful carry the load. For additional information on the contents of the DD submittal, please see appendix B, which contains the entire DD submittal. Construction Documents. The third phase of this project was creating the construction documents. This package contains everything necessary to fabricate and construct the structural system for this building. The first step in this process was reviewing the feedback from the DD submittal. The feedback implied that some of our detail drawings were not clear enough to be constructed, so that was remedied. Once we had made the necessary changes to existing plans, we moved into completing the new tasks. Page 9

The biggest challenge with the CD submittal was presenting all of the necessary information in a clear manner due to the limited amount of space on the plans, and each member needed to be labeled and dimensioned. In order to clearly present all necessary information, plan notes were used as much as possible. Each member was labeled as clearly as possible and specific attention was paid to minimizing the use of leader lines. The CD plans have a much higher level of detail and are very clearly explained, whereas the DD plans gave a good indication of member location but were not completely buildable. For your convenience, the complete CD submittal has been included in Appendix C. Construction Administration. The fourth phase of the project was the Construction Administration phase. On a real project this phase is during the actual construction of the building. During the CA portion of the project the engineer has already completely design all necessary elements for the structural system to be erected. The engineers job during the time the structural system is erected is to solve any problems that arise. Perhaps a coordination issue causes a pipe and a beam to be at the same height. The structural engineer would be responsible for finding a solution. For our CA submittal we were required to solve a theoretical problem. The problem was that one of the shear tabs, the component that connects the girder to the column was installed 1 too low. As a result, the bolt holes did not line up on the girder. Students were required to respond to the Request For Information sent out about the problem with a reasonable solution. The solution my team came up with was welding the shear tab to the girder. A 12 long, 3/16 weld was strong enough to withstand the loading. For corresponding calculations and a detailed drawing solution please the RFI and our solution in Appendix D. Page 10

Calculations. The final submittal of our project was the calculations submittal. On a real project the calculations would have needed to be done prior to the construction document phase. Although these calculations are typically never submitted because contractors only need the results, within the scope of the classroom setting submitting calculations was critical. Our calculations package included all of the math required to size the structural components for the building. Both hand calculations along with computer calculations were utilized. All computer calculations were performed in Microsoft Excel. Excel enabled us to make adjustments without having to redo all of our equations, however each formula in excel had to be created and programed by us. Not every member and connection in the entire building was included within our calculations submittal. The submittal includes one of each typical component. This includes one column, beam, girder, connection, interior footing, and column base plate. Also required in the calculations submittal was all the applicable loading condition calculations for factors such as snow, wind and snow. Altogether the calculations package is roughly 27 pages. There are a few discrepancies between the construction documents submittal member sizes and the calculations submittal member sizes. This is due to the calculations not being entirely done when the CD submittal was due. In a real world setting the calculations would have to be completed and then the results are published in the CD submittal. The calculations submittal has included in Appendix E for your convenience. Conclusion Structural design is not an easy process. It is very complicated due to the numerous factors that contribute to the various loads. However, it is a process that can be broken down into a few, very systematic steps. Overall structural design is truly an art; an art which requires both analytical and creative inputs. There are several considerations that go into designing structural Page 11

systems. The ultimate goal of the structure is to keep the building standing and preserve life safety. Keeping this goal in mind, the structural system is designed to meet all aesthetic and architectural requirements. An engineer s true job is problem solving. They are responsible for coming up with a solution to the problem the architect and the owner have created. A successful solution will meet all design requirements as well as all code requirements. This project has given students a preview of just how challenging it is to create a viable solution. Page 12

Request For Information (RFI) 001 Subject: Structural Steel Project: LCCC Student Services To: ARE 4720 Design Team From: Bob the Builder Date requested by: May 13, 2016 5:00 p.m. Request: A single shear tab connection with (4) bolts on a W18x35 beam was installed 1 too low. The required capacity is Ru= 45 kips. Please provide field fix for connection. You can provide a verbal or drawing response. Verbal responses shall include enough information that it is contructable. Answer: In response to RFI 001 we have come up with the following solution. Please raise the beam to the original specified installed height then field weld the beam to the shear tab. No bolts are required. A single 12 long, 3/16 fillet weld down the long side of the shear tab will provide a connection of adequate strength. Please see attached drawing and calculations for more detail along with capacity verification. If you have any questions or concerns regarding this solution please do not hesitate to contact me.
