Armtec is a major manufacturer of precast prestressed concrete girders designed to support bridge decks and traffic loads. The durability, cost effectiveness and low maintenance of precast concrete, have made it the dominant structural material for short to medium span bridges. Armtec girders are manufactured under controlled factory conditions. While prestressed beams are designed for single-span applications, some girders can be post-tensioned to form continuous spans. Proven strength Durable, cost effective and easy to maintain Readily available Manufactured year-round in controlled conditions TYPICAL APPLICATIONS Road bridges Pedestrian bridges Rail bridges For girder details applicable to regions outside of Armtec s Prairie Region, refer to the appropriate Bridge Girders Technical Guide In-house engineering and installation Able to meet unique aesthetic, schedule, span and load requirements Various girder types NU, trapezoidal, single box, Saskatchewan SLC, SL and SLW available CALGARY, AB - FOOTHILLS CONNECTOR AT 16 TH AVENUE CALGARY, AB - M c KNIGHT FLYOVER AT 36 TH STREET 2

NU GIRDERS MATERIAL PROPERTIES Concrete The high level of prestressing will normally require the use of high strength concrete. The span capability diagrams were developed using a 28-day concrete strength of ƒ'c=70mpa. The unit weight of concrete was assumed to be 2,450kg/m³. The concrete may contain silica fume with air entrainment of 5% to 8%. The modulus of elasticity of concrete was calculated using the formula: The minimum release strength assumed was 45MPa. Where there are two dashed lines in the charts, they represent limits for 45MPa and 50MPa release strength. Any point on a chart above the 45MPa line indicates a situation where the release strength has to be higher than 45MPa due to handling stress limitations. This situation would require special mix designs which may increase the cost. The concrete deck 28-day strength was assumed to be 45MPa.

SPAN CAPABILITY Prestressing Strand The prestressing strand is 15mm in diameter, uncoated, seven-wire, low relaxation strand, and meets the requirements of ASTM A416, with an area of 140mm². The initial jacking force is 75% A p ƒ pu = 195kN Girders with a Span to Depth Ratio >20 typically use up to an additional four 15mm strands in the top flange to control the lateral stability of the girder at handling and transportation. End stresses were not checked for all span conditions indicated in the charts. Stresses may be controlled by debonding and/ or deflecting selected strands at the ends of the girders. Post-Tensioning NU Girders may be post-tensioned to form continuous beams. Reference should be made to CAN/CSA-S6. For long span post-tensioned bridges, oiled strand (using approved corrosion inhibiting oil) may lead to decreased friction coefficients. Contact a local representative for more information about Armtec s experience constructing bridge beams with oiled post-tensioning strand. DESIGN CRITERIA The span capability charts were developed in accordance with the CAN/CSA-S6 Canadian Highway Bridge Design Code. Simple spans were assumed for all loads Calculations were done for interior girders.
