Abstract: The connected high-rise building of Bubugao headquarters in Wujiang is composed of two high-rise monomers, which are connected by steel truss in high position.The process of the performance-based analysis were presented, and the analysis of the steel struss were presented in detail. As shown in the results, the structural system is rational, and every property index can satisfy the seismic performance requirements.

Keywords: connected structure; performance-based analysis; steel truss
