Abstract In this study 4‐, 10‐, and 30‐story staggered truss systems (STS) were designed and their seismic performances were evaluated by pushover analysis. The results were compared with the seismic performance of conventional moment‐resisting frames and braced frames. According to the analysis results, the STS showed relatively satisfactory lateral load‐resisting capability compared with conventional braced frames. However, in the mid‐ to high‐rise STS, plastic hinges formed at horizontal and vertical chords of a Vierendeel panel, which subsequently led to brittle collapse of the structure. Based on these observations, reinforcing schemes were applied and their effects on enhancing lateral load‐resisting capacity were investigated. Copyright © 2007 John Wiley & Sons, Ltd.
