Experimental Research on Endplate Bolted Connection with Steel Beam and Reinforced Concrete Column/Mao Weifeng1, Xiao Yan1,2,Li Xian1,Guo Yurong1(1 College of Civil Engineering,Hunan University,Changsha 410082,China; 2 Dept.of Civil Engineering of Southern California,CA90089,USA)
Abstract:A new type of endplate bolted connection with steel beam and reinforced concrete  column is investigated,and three fullscale connections were tested under simulated seismic loading.Experimental results show that this new type of composite connection has satisfactory seismic performance with excellent ductility as well as good energy dissipation capability.
Keywords:posttensioned high strength bolts; endplate; composite connections; seismic behavior
