T形头单向螺栓连接T形件-钢管节点抗拉性能研究
Tensile Performance of T-Stub to Steel Tube Joints with T-Head One-Side Bolts
摘要
Abstract
The novel T-head one-side bolt can effectively solve the problem that the traditional high-strength bolt cannot be directly applied to the endplate connection of beam to steel tube column joints,and the construction is relatively simple.However,the bearing mechanism of each component in the beam-column joint with this novel bolt is still unclear and needs to be further explored.The main difference between the traditional high-strength bolted joints and the T-head one-side bolted ones is the shape of the bolt holes on the endplate and tube column.To explore the mechanical response and bearing mechanism of the tube column component in this novel bolted connection,the finite element analysis software ABAQUS was used to carry out a systematic numerical analysis on the tensile performance of the T-stub to steel tube joints based on the component method.The main research contents and conclusions are as follows:An accurate three-dimensional finite element model of the joint was established,and the yield line pattern of the column wall in the T-head one-side bolted joint was studied.Finally,the calculation formula of the bearing capacity for the column wall under the novel yield line pattern was given based on the principle of virtual work and the yield line theory.关键词
