Seismic Performance of Cantilever Beam-Column Joint with Z-shaped Fully Bolted Connection and Double Friction Surfaces at the Flange
摘要
Abstract
In order to study the seismic performance of a new cantilever beam-column joint with Z-shaped fully bolted connection and double friction surfaces at the flange,relevant specimen was designed for pseudo-static test and finite element analysis.Additionally,parametric analysis of the new beam-column joint was conducted using finite element simulation to verify the applicability of the proposed joint design method.The results show that the new joint experiences bending failure at the beam end,ultimately cracking at the weld between the cantilever beam flange and the steel column.There is no sliding phenomenon in the connection section,and the hysteresis curves are plump without pinching.The bearing capacity of the joint is high and the deformation capacity is good.The finite element analysis results are in good agreement with the experimental results.When the bolts are configured with equal strength connections,the hysteretic properties and failure modes of the joint models with different section sizes are similar,and the rigid joint design method according to the specification can be used to design the joint.关键词
