Evaluation of the seismic performance of suspended zipper column concentrically braced steel frames

Based on the comparison of results, it can be concluded that the performance of suspended zipper frame is better than that of conventional concentrically braced frames in medium-rise buildings, but not in low-rise buildings. Furthermore, the novel design methodology is proven to be satisfactory in sizing the structural elements of suspended zipper concentric braced frames when considering the inelastic time history analyses results.
