Research for node of CFT column to steel beam connections with stiffening L-plate

WANG Xiuli,XIA Pei (School of Civil Engineering,Lanzhou University of Technology,Lanzhou 730050,China)  
The node construct and the force analyze between the CFT column and beam is a key technology to develop combined structure system,with the software of ANSYS,this study have a space nonlinear finite element analysis on a typical node of the CFT column and steel beam,analyze the stress distribution situation and inner force actuating mechanics of the node in the symmetric load.Meanwhile,by changing the parameter of stiffening plate,analyze the chief factor that effect the stiffness of the node,determine the influence rule that the parameter of stiffness of the node have on the stiffening L-plate node.The result indicate,by setting stiffening plate,the stress concentration is reduced effectively,make the steel generate obvious plastic ream,reducing the probability of the node damaged largely,meanwhile,analyzing the parameters that effect the stiffening plate.Then according to the results,the improved suggestion and reference of this style node are appealed.
