Experimental Study on One-Side Bolted Strengthened Beam-to-Column Joints
摘要
Abstract
In the reported experimental studies on T-head square-neck one-side bolts(TSOBs)bolted beam to square hollow steel(SHS)column joints,bolt pulling-out caused by SHS column wall bulge deformation is typical.To avoid the SHS column wall deformation under the bending moment of the beam end and to improve the joint deformation capacity,two types of assembled strengthening components were proposed in this paper,and static performance tests under monotonic load were carried out on four joints with the strengthening components to explore the influence of the type and length of strengthening components on the joint structural response.The test results show that strengthening components can avoid bolt pulling-out failure,with double-channel component and H-steel component increasing the yield bending moment of the joints by 8.1%～31.8%and 72.1%～72.6%,and the peak bending moment by 11.6%～21.7%and 36.7%～38.1%,respectively.The extended H-steel component is recommended for use in TSOBs bolted beam to SHS column joints,and its cross-section can be designed based on the joint internal forces.关键词
