Moderate Seismic Regions

Steel concentrically-braced frames (CBFs) as a lateral force resisting system are widely used in moderate seismic regions. The collapse capacity of CBF is uncertain in prior study so that an appropriate analysis method is hard to hunt. Incremental Dynamic Analysis (IDA) is an efficient method to evaluate the dynamic instability of structure. The IDA is incorporated in evaluation of collapse capacity of CBFs systems and IDA-based collapse ductility spectra of CBFs are concluded in this study. Variable periods range of CBFs systems considering reserve capacity are determined based on the IDA.

Incremental Dynamic Analysis (IDA) is a technique to determine the overall seismic performance of structures under varied intensities of earthquakes. In this paper, the seismic performance of four-story steel braced frames equipped with superelastic Shape Memory Alloy (SMA) braces is assessed by performing IDA. The seismic response of SMA-braced frames was compared to that of corresponding Buckling-Restrained Braced Frames (BRBFs). Based on the results of this comparative study, the SMA-braced frames were generally effective in reducing maximum interstory drifts and permanent roof deformations. In addition, the SMA-braced frames demonstrated more uniform drift distribution over the height of the building. As the intensity of earthquake excitation increases, a higher response reduction can be expected for SMA-braced frames.
