Paper Title:
Seismic Behavior Study on Improving Beam-Column Connections in Portal Frames
  Abstract

The beam-column joints of steel solid-web portal frame has high stress concentration, which cause brittle fracture of plate under reciprocating load. Low reciprocating load test and finite element analysis for three kinds of joints, Discussing the ultimate bearing capacity, hysteretic performance and fracture mechanic properties, Which the results shows that: the bearing capacity of improved joint has grater increased than the joint with endplate keep upright; when load to limit state, the flange plate of joint with endplate keep upright has strong fracture performance, this point has been proved during the experiments; According to the numerical distribution of cracks factor, can qualitative identify dangerous position of component, as a basis of fracture fortification for structure.
