This paper presents the experimental results of eight full-size specimens with four types of connection details under cyclic loa.ding.The moment resistance and ductile behavior of these specimens are analyzed, and the sensitivity to fracture failures is assessed. Based on the experimental research, the design suggestions on modifying connection detail are proposed.
Keywords: beam-column connection; fracture failure; joint test
