Abstract

Steel-glulam structure is a new type of composite structure,glulam have lateral support effect on steel plate, that can prevent premature buckling of steel plate and improve the stability of steel structure. In order to study the influence of column’s cross-section form on the seismic performance of steel-glulam composite beam-to-column exterior joint, the column’s cross-section form was taken as the basic variable (glulam rectangular section , H-beam section and H-beam-glulam rectangular section were used respectively). The pseudo-static tests of three composite beam-to-column joints were carried out to observe the different failure modes, and obtain the mechanical performance indexes. The experiment results demonstrated that: The energy dissipation capacity of beam-to-column exterior joint composed of glulam column was the worst, the ultimate bearing capacity and stiffness were the lowest. The ultimate bearing capacity of the exterior joints formed by the H-beam column and the H-beam-glulam composite column were both high, and their ductility coefficients were similar, while the former had better energy dissipation capacity.

钢-胶合木组合梁柱外节点的拟静力试验

钢-胶合层结构是一种新型的组合结构，胶合层对钢板具有横向支撑作用，可以防止钢板过早屈曲，提高钢结构的稳定性。为了研究柱的截面形式对钢-胶合板组合梁柱外节点抗震性能的影响，将柱的截面形式作为基本变量(分别采用胶合板矩形截面、h型钢截面和h型钢-胶合板矩形截面)。对3个组合梁柱节点进行拟静力试验，观察其不同的破坏模式，获得其力学性能指标。试验结果表明:由胶合木柱组成的梁柱外缝耗能能力最差，极限承载力和刚度最低;h型钢柱和h型钢-胶合柱构成的外部节点的极限承载力均较高，且延性系数相近，但h型钢柱具有较好的消能能力。
