ABSTRACT:

The resilient prefabricated prestressed steel frame (RSF) has been proposed and researched by the researching group, which can effectively control structural damage, reduce or eliminate residual deformation of the structure, be feasible to repair after undergoing seismic actions. Focusing on the steel structures with large spans locating in high seismic zone, a new RSF with intermediate columns containing friction dampers (RSFFD) has been proposed. In this thesis, based on the accomplished pseudo-dynamic test of RSF, two 1 bay-4 floor models toward the RSF and RSFFD are established, dynamic time-history analysis of both models under various magnitudes are carried out by adopting software ABAQUS, and numerical simulating results of both frames are achieved and compared to investigate the seismic performance. From analyzing results, it can be concluded that intermediate-column type friction damper (ICFD) can not only improve the lateral stiffness of RSF significantly, control the inter-story drift effectively but enhance energy dissipating capacity under design and rare earthquakes and reduce the plasticity development and structure damage of the main parts.
