| Abstract: | In reference,two types of specimen tests,"weak beam-strong column-strong joint" and "strong beam-strong column-weak joint",were carried out.Experimental results show that the first type of specimen has a very good performance.When the expected failure occurs in the beam,its joint still remains at the elastic stage.The second type of specimen was used in the tests to force failure to occurr in the joint,in order to study and evaluate the distribution of joint shear force at different stages.This paper focuses on study of the shear bearing capacity for composite circular column-steel beam connections under cyclic loading.Based on the data of the experiment,the proposed calculation approaches for joint shear force at the primary cracking stage and yielding stage for composite circular column-steel beam connection are presented. |
