7 HALFEN CAST-IN CHANNELS HTA-CE General European Technical Approval ETA In 00 the European Technical Approval ETA-09/09 was granted by the German Institute of Building Technology (DIBt, Deutsches Institut für Bautechnik) for the HALFEN HTA-CE Cast-in channel. This new approval is valid without restrictions in 0 European states. ETA - 09 / 09 -CPD-89-0 Calculating the anchor channels that are included in this ETA is done according to the new European standards series CEN/TS 99- Design of anchorages for use in concrete. This standard series summarises the current state of technology in dimensioning anchorages in concrete and takes current research in the field of anchoring systems into consideration. Advantages of HALFEN HTA-CE Cast-in channels It is possible to consider various concrete strength classes, geometric boundary conditions and any load combinations. As a result, the designer works in conformity with the approval in all application situations. This makes decisions easier and also minimizes disagreement on technical or legal issues with building authorities, test engineers or consultants. The planning engineer has numerous options for influencing the result and can therefore work out the most economical and technically effective solution. For example, the load bearing capacity of the overall system can be positively influenced with different reinforcement models. A comprehensive and sophisticated test program is needed to acquire an ETA. Furthermore, all further criteria required for approval must be satisfied. Planners and users can rest assured that the HALFEN HTA- CE Cast-in channels have all assured properties. Moreover, the properties of different products are comparable, as these are determined with a clearly defined and identical test program. Planners and designers who use HALFEN HTA-CE Cast-in channels in compliance with the European Technical Approval also observe the national building regulations of 0 European Union Countries. Furthermore, the CE mark verifies that all criteria of the ETA have been met. The anchor channels approved in this way can be used beyond national boundaries. Consequently, planners have maximum planning certainty for international projects. This also applies in particular for prefabricated concrete parts which are very frequently CE marked as one component. As the ETA also includes detailed specifications on internal and third party quality control of ongoing production, the user can rest assured that HALFEN HTA-CE Cast-in channels always correspond to the same high quality as the samples tested in the initial approval procedure. 0 HALFEN B -E

8 HALFEN CAST-IN CHANNELS HTA-CE General European standard CEN/TS 99- Planning standards apply for the whole of the European Union The new European standard CEN/TS 99- was issued in 009 and covers the design method for Design of fastenings for use in concrete. This approval represents current state of the art technology standards and may be used in all applications. To apply the new European cal culation method, product specific values such as load bearing capacities or form coefficients are necessary. These and further special regulations for dimensioning are included in the ETA-09/09 (European Technical Approval). This new calculation method is supported by a comprehensive user-oriented and easy-to-use design software. What is the CEN/TS 99- A European CEN standard was created with the aim of standardising the dimensioning of fastenings in concrete to a common basis. Cast-in fixings such as anchor channels and headed fasteners as well as post-installed anchors are regulated in this standard. The standards committee CEN/TC 0/ SC /WG Design of fastenings for use in concrete was founded in 000 with members from nine European nations. In 009, the set of regulations was published as CEN/ TS 99-, TS Technical Specification. ETA - 09 / 09 -CPD-89-0 This is a preliminary standard with the aim of converting to a European standard. With its publication this new standard will then represent state of the art technology and may be used in practice. 8 0 HALFEN B -E

9 HALFEN CAST-IN CHANNELS HTA-CE General European standard CEN/TS 99- This preliminary CEN/TS 99- standard has five parts: General Headed bolts Anchor channels Dowel Mechanical Dowel Chemical With the switchover to one standard, this technical specification will become part of the European Concrete Standard EN99. Paving the way for the future already today is the publication of the ETA, the publication of all resources and documents as well as personal consultations. CEN/TS 99- may only be used if a technical specification is available for the fixings, which confirms the suitability of the product and which contains the characteristic values necessary for dimensioning a fixing. For building products, a ETA (European Technical Approval) represents this document. The approval for HALFEN HTA-CE Cast-in channels is the ETA-09/09. The European Technical Approval is a confirmation of the usability of a building product as defined by the Construction Products Directive (CPD). The ETA is based on tests, assessments and a technical evaluation by expert bodies appointed by the member states of the EU. It comprises all product characteristics which are significant for compliance with statutory requirements in the member states, whereby the relevant requisite performance level may differ nationally or may depend on the intended purpose. The transmission of the loads applied locally into the channel must be verified. For this purpose, Part of CEN/ TS 99- provides a method for calculating the resulting anchor loads. The resistances to steel failure are listed in the European Technical Approval ETA. The load bearing capacities are provided with dimensioning equations. Here all influences on the load bearing capacity of the anchor channel are taken into consideration. The HALFEN Cast-in channel may be used in all concrete strength classes from C/ to C90/0. The planned strength is incorporated in the verifications. The flexible dimensioning concept allows for the development in reinforced concrete construction towards using ever lower component thicknesses with higher concrete strengths. For example, the resistance to concrete failure is % higher in a concrete of strength class C0/0 than in concrete of strength class C0/. It is therefore possible to compensate lower edge distances with a higher concrete strength. CE Marking HALFEN HTA-CE Cast-in channels are ETA approved and are therefore CE marked. This allows the user regulated access to the European market. The CE mark is the visual mark that a product corresponds to the requirements of the European Community imposed on the manufacturer. It may only be applied if a directive with intended CE mark applies for the product. With the CE mark, HALFEN declares that the product conforms with the essential requirements of the applicable EC directives.

27 HALFEN CAST-IN CHANNELS HTA-CE Software HALFEN Software HTA-CE The new HALFEN calculation program for HALFEN Cast-in channels with European Technical Approval (ETA) provides the user with a convenient and very powerful calculation tool. Although HALFEN Cast-in channels could previously be selected from tables according to their load bearing capacity, the ETA requires a wider range of verifications for cast-in channels and the concrete used. These verifications are processed by the user-friendly HALFEN software. In just a few seconds the user is presented with a list of suitable HALFEN Cast-in channels for the relevant load situation. Boundary conditions The calculation takes into account all necessary boundary conditions, typical examples being: cracked or non-cracked concrete the concrete components geometry, in particular the distances of the channel to the component edge various reinforcement patterns consideration of several dimensioning or characteristic loads positioning of the loads with a definable adjustment range, and the option of shifting the defined bolt pattern along the complete channel length verification of the required HALFEN T-head bolts and if required also for stand-off installations engineering consideration of fatigue loads and fire influence Input The geometry and loads are entered interactively. Entries are displayed promptly in a D graphic. Entries can also be changed directly in the graphic. Click on the load, the measurement or the component line you want to change to make the required modification. Results After calculation, the software output provides either the results for a preselected profile, or in the case of automatic selection a list of all suitable profiles. Profiles and T-bolts with in-complete verifications are highlighted in red.

40 HALFEN HGB HANDRAIL CONNECTIONS General Regulatory requirements Balconies are part of the structural system. "They must be designed, constructed, maintained and modified in such a fashion that public order and safety, especially health or life is not endangered". (MBO = Musterbauordnung / model building code 0 and construction guidelines). Applicable technical and building codes regulations must be observed. Technical rules provide information on load parameters, calculation, dimensioning of structural products, construction types, structural layouts etc.. A requirement of regional building codes refers to structural stability: "All structures must, as a whole and in its individual components be structurally self-supporting". This stability must be statically verifiable based on current technical standards (see DIN 0 Sections +). A further building regulation addresses traffic loads, for example: Balconies and loggias must be fitted with safety rails to prevent falls when they border on to an area with a drop of more than one meter. For a drop height up Regulations, standards and directives to be observed when designing safety rails: Regional Building Codes VOB Part B,, execution: BVM Directive Other applicable regulations and Standards (Extracts): to m the minimum banister height is 0.90 m measured from the upper surface of the finished floor surface or accessible ledge. For drop heights greater than m the banister height must be at least.0 m. For exceptions see the German Federal building regulations / Deutsche LandesBauOrdnung. Other regulations, not covered here, address the design, fire protection, thermal / sound insulation, rainwater drainage, dimensioning, postioning and spacing of safety installations. Individual regional states have their own building codes and regulations. All technical regulations require proof of structural safety and integrity. A static calculation or a regulated certificate is required when designing and dimensioning safety rails.. () It is the contractor responsibility to provide the static documentation in accordance with the contract. He has to observe the recognized standards of practice as well as with the provisions of the law and regulatory directives. VOB (Vergabe- und Vertragsordnung für Bauleistungen / Tender and Contract Regulations for the German building industry) Part B,., requires the contractor to report to the customer, in writing, any obvious design flaws, which he, as the expert, must be able to recognize. He alone is responsible for any resulting defect and consequential expenses. If he has satisfied his reporting obligation, the responsibility for the defect passes to the customer (defect example: banister attachment mounted in too thin a concrete slab).

44 HALFEN HGB HANDRAIL CONNECTIONS Dimensioning Fundamentals Banister height The minimum height h b of a banister is 0.90 m from the top edge of the finished floor or accessible ledge to the upper edge of the rail. For drop heights of more than.0 m the banister must be.0 m in height. (Exceptions; as specified in regional building codes) It would be advisable to have one uniform minimum height of.00 m as has already been mandated in the commercial sector and in a number of other European countries. Balcony slab Anchor channels or dowel installations require concrete of at least grade C 0/. If the concrete grade is less than grade C 0/ or it is unknown, a case-by-case decision must be made. The thickness of the balcony slab must be at least h = 00 0 mm when the HGB is mounted in the slab edge (depends on channel profile and according to German HGB approval). Other types of installation and systems require a thicker slab. All weather-exposed concrete-embedded installations (e.g. for balconies) must be made of stainless steel. Clearances Any structural design must take all basic requirements for railings and banisters into account. As a general rule, all railings and banisters must be designed so that personal injury is ruled out, for instance with correct spacing of rails, lattice bars or panels. They should also be designed so as not to entice but instead to discourage anyone from climbing over. The specific requirements for railing design are determined by the intended use (residential, public, commercial) and the drop height involved. Also observe the building codes of each country or region, the ETB guidelines Fall Protection Components and DIN 80 (Stairs in Buildings definition, rules, key measurements). b Rail height hb OK FF h b = clear distance between the back of the veneer and the front face of the balcony slab or gutter / kick plate clear distance between bottom edge of hand rail and top edge of facing / lower structure clear distance between the top edge of the finished floor and the bottom edge of the facing / lower structure axis spacing between posts clear distance between horizontal facings clear distance between vertical facings 0 HALFEN B -E

Rafter roof static system: F,d < FRd F,d FN,d The maximum rafter strength is limited by the design load of each individual component of the rafter shoe. Load tests resulted in a mean breaking load of 0 kn. With normal loads larger than the recommended load capacity (= about / of the breaking load), the rafter spacing may need to be reduced. If lower loads are present then the minimum edge distance C, for the HALFEN Cast-in channels can be reduced. The distance to the concrete edge must be at least 0 mm. Make sure that the HALFEN Cast-in channels are installed flush with the concrete surface. Use spacers if necessary. 0 0 HALFEN B -E

73 HALFEN CURTAIN WALL SUPPORT SYSTEMS HCW General HALFEN Curtain wall system This type of construction is characterized by an outer wall with a continual outer skin (see figure ). The façade is attached to the main structure of the building using only the required number of point-load connections. Curtain wall façades protect the interior of buildings from external, unwanted environmental influences whilst still Post and beam façade and the modular façade. Basically, we distinguish between two methods of curtain wall façades constructions: the post and beam façade and the modular façade. Post and beam façade One basic distinctive difference is the way expansion in the façade is distributed, (for example from heat expansion). With the post and beam façade (see figure ) the vertical and horizontal frame supports are installed in spacings corresponding to the façade elements. The supports are installed with an expansion gap between components allowing sufficient expansion. The respective longitudinal and transverse connections have a expandable joint. The filler elements (glass or panel) installed in a post and beam structure permit movement within the tolerance of the designed expansion joint. The glass and filler elements are delivered separately and are then installed on-site, requiring on-site scaffolding. permitting visual-contact with the outside environment via structural components that can be opened or are transparent. Specifically, this includes sufficient stability against wind loads, adequate insulation against frost in winter, the heat in summer as well as against external noise. In addition, various requirements must be met to protect against fire and other critical situations. Post and beam façade Plan View Modular façade With the modular façade method, (see figure ), the façade is made of prefabricated elements, in which glass, natural stone or infills are pre-installed. The façade profiles are designed as a key and slot system to allow for expansion. Curtain wall figure partial view of façade Plan Modular façade Figure View Figure section This method provides immediate weather protection and allows the building contractor to start interior work on the respective floor directly after the prefabricated modules have been installed. Scaffolding is not required with this method of construction. HZA Channels HTA-CE Channels 0 HALFEN B -E

The factors are dependent on the bracket geometry, the load direction and the bolt position (see figure on the right). See table below for the multiplication factors for determining the design-reaction forces in the HALFEN Bolts.
