Q460高强钢螺栓抗剪连接承载性能有限元分析
Finite element analysis of bolt shear connection bearing capacity of Q460 high strength steel
摘要
Abstract
The performance and quality of high strength steel connection node are essential for the better application of the bearing capacity of high strength steel.In order to make a discussion of the application of different standards,the parameter analysis is made to bolt pretension force,the surface state of connecting plate,steel grade and thickness of connecting plate,compared with theoretical calculating value of standard GB500017,ANSI,EC3.The result shows that the bolt pretension force has no effect on shear strength and deformation;if the anti-slip factor increases from 0.35 to 0.50,the deformation value will decrease by 15.5％,and the bearing capacity almost has no improvement.If the steel yield strength increases from 345 MPa to 690 MPa,the bearing capacity increases by 1.58 times,but the deformation capacity obviously decreases and the ductility weakens;the connection bearing capacity can be obviously improved by the increase of steel thickness,with the failure in connection caused by crosswise tear of steel plate caused by bolt shear.关键词
