Design and analysis on the reinforcement of the beam-column connections with welded flanges and bolted webs

SHI Yong-jiu,YANG Wen,WANG Yuan-qing(Department of Civil Engineering,Key Laboratory of Structural Engineering and Vibration of China Education Ministry,Tsinghua University,Beijing 100084,China)  
During the Northridge earthquake in America and the Kobe earthquake in Japan,the form of connections with welded flanges and bolted webs suffered unanticipated brittle fractures in many steel moment-resisting-frame buildings.Many researches on repair and rehabilitation have been carried out for the damaged steel moment connections after the disasters.However,the researches in our own country now lag behind.This article summarizes the causes of the damaged the main approaches abroad of reinforcing the connections with welded flanges and bolted webs.Based on the available experimental results in America,it also displays the design process by analyzing an example,and compares the differences between the notions of the design before and after the modification in China and abroad.It turns out,also confirmed by finite element analysis,that the seismic resistant performance of the connections can be improved after proper reinforcement.
