Abstract
The analytical study herein focuses on the investigation of structural systems consisting of steel frames with reinforced concrete infill walls (SRCW) for using as the primary lateral-resistance systems for low-rise structures in the seismic zones. Due to need of a richer understanding about the cyclic behavior of this composite structure, the work reported in this thesis attempts to build a model in PISA3D software including partially-restrained steel frames with reinforced concrete infill walls. The lateral behavior of infill walls was predicted by the Simplified Strut-and-Tie (SST) model, and modelled by equivalent truss elements. While the pushover analysis of the equivalent truss elements was carried out by Fracture material in PISA3D, their cyclic response was performed by Degrading material. Moreover, a three-span three-story building in California was designed for seismic resistance by this composite structure. The preliminary design followed ASCE 7-10, then the seismic performance was predicted by the capacity spectrum method (CSM), a nonlinear static analysis with 3 procedures A, B and C which were adopted in ATC 40-96. The performance of SRCW frames was compared with a Self-Centering Braced Frames (SCBF), and a traditional Moment Resisting Frames (MRF) by SEAOC Vision 2000. In addition, although PISA3D software can not run the time history analysis (THA) for SRCW frames, a comparison between the THA and the CSM for the SCBF and the MRF was carried out.
