Substructuring pseudo-dynamic simulations on real inelastic responses of steel braced frame monitored during moderate earthquake

This paper presents a series of substructuring pseudo-dynamic tests on steel brace members in order to simulate the real inelastic responses of the steel braced frame monitored during moderate earthquakes. A pair of brace members at the first story were chosen as sub-structure specimens for loading tests. As for other fictitious portions, linear-elastic behavior was assumed, and the whole system was solved as a shear-type 3-DOF planar system. Monitored responses and the tests results are also compared with completely numerical response analysis using a mathematical model for brace members.(AU)
