摘要：

The end-plate connection is a kind of node in the steel portal frames and multistory steel frame structure, but the study on stainless steel end-plate connections was not carried out previously. So four specimens with various details including four types of bolts(10.9, 8.8, A4-70, A4-80) and two types of end-plate thickness, were tested under cyclic load to investigate the influence on the failure mode, ultimate capacity and ductility of various connections. Test results show that the hysteresis curve of the connections with stainless steel bolts is Z-shaped and the energy dissipation is 40%, lower than that of high strength bolts, and that when the end plate is thinner, its seismic performance is significantly improved. The finite element models were built and proved accurate based on the comparison between results from the finite element analysis and tests. Hysteresis curves of all specimens have different degrees of pinching. The weaker the strength of bolts and the thinner the end plate, the more obvious the pinching, demanding improvement in designing. And new processes should be developed for the widespread use of frictional bolts in stainless steel. © 2017, Editorial Board of Journal of Tianjin University(Science and Technology).
