Abstract :

The most popular system for supporting long-span roofs is steel truss in commercial buildings, such as warehouses and aircraft hangars. There are numerous advantages of steel trusses, such as lightweight, ease of handling and erection, and geometric flexibility. However, there are some drawbacks, in terms of the material selection during the design time and material availability during the construction phase, maintenance cost, and low fire resistance. Hence In this presentation, Precast Prestress and Post-Tensioning Concrete and steel built-up box girders would be presented as an alternative to steel trusses for spans up to 40 to 50 m without intermediate supports. The design behavior and constructability perspective by illustrating by the help of CONCISE V 4.47h model. This proposed design is easy to produce, fabricate and erect and has lower construction and maintenance costs than steel trusses. the proposed design. A finite element analysis of the specimen is conducted to investigate stresses at long span precast prestress and post-tensioning and steel built-up girders. Further, the complicated transportation and erection sequence would be illustrated with practical examples to erect the heavy, long span beams.
