<strong>Paper Title</strong><br> Behaviour of Steel Staggered Truss System under Seismic Loading<br> <br> <strong>Abstract</strong><br> Staggered truss system is a prospective steel structure system for multi-story and high-rise buildings. The staggered truss framing system arose from the use of system design techniques to improve efficiency in building construction. Staggered truss systems have proved to be effective in integrating the structural and mechanical requirements. In addition, cost reductions arising from reduced steel tonnage and reduced building volume may be achieved from the use of these framing methods. The purpose of this project is analytical investigation on the behavior of an 8-storey steel staggered-truss system using the ETABS software. The parameters such as the structural truss type, arrangement of the trusses are varied, and their influences on seismic behaviors of the system are studied. And based on the test results, some indices of seismic behaviors of the system, such as yield load, deformation and strength are analyzed.
