H型钢梁与矩形钢管柱端板单向螺栓连接节点初始转动刚度性能
Initial Rotational Stiffness of H-shaped Beams to RHS Column End-plate Connections Using Blind Bolts
摘要
Abstract
Tests of six groups of flushed and extended endplate connections using blind bolts were carried out.Based on the existing research results,the stiffness formulas of blind bolts in tension,end plate in bending,column wall in tension,column wall in compression and end plate in compression were derived.The theoretical calculation formula of the initial rotational stiffness of flushed and extended connections under bending moment was proposed by means of the component method.The results show that the calculation formula of the initial rotational stiffness of connections is in good agreement with the test results,and the precision can meet the requirements of engineering design.Finally,the design proposal of H-shaped steel beams to rectangular hollow section (RHS) column end-plate connections using blind bolts was put forward.关键词
