Experimental Study On Behavior And Seismic Details Of Joints Consisting Of Steel Beams And Src Columns Under Cyclic Loading

Through a test for large-scale specimen under low frequency cyclic loading, the aseismic performance and structural measure of steel beam-SRC column frame joints were studied. The mechanism analysis of it was also carried out in this thesis. When designed with the weak-beam rule, the test result showed that the failure type of steel beam-SRC column joint was beam hinge failure type while its core was well undestroyed and the intensity, ductility and energy absorption requirement were well satisfied. Otherwise, when the beam was stronger and the joint core was weaker, the failure type of the joint was shear failure type. Unlike RC joints, due to the effect of the steel in the joint core, the ductility of SRC can reach 4 or more. The result also showed that using FBP plates could improve the joints~ aseismic performance.
