摘要:
为研究六边形孔钢梁-复合焊接闭合箍筋约束砼柱空间组合件的变形性能,对9个梁柱平面及空间组合件的1/2比例模型施加低周往复荷载.通过测量各位移幅值下测点的变形,分析各测点变形的发展规律及所占总变形的比例,明确结构相对应的破坏类型,为土建工程实际施工设计提供理论的变形容许值.试验结果表明:位移角为1/250,1/65,1/45,1/20 rad分别与组合件整体完好、轻度破坏、中度破坏、重度破坏4种类型相对应,其值可作为不同性能要求的建议变形容许值,组合件梁端弯曲变形导致的层间水平位移占层间总位移的百分比最高.
Abstract:
In order to study the deformation performance of the spatial subassemblage consisting of the hexagonal hole steel beam and concrete column constrained by composite welded closed stirrups, the experiments of nine 1/2-scale beam-column plane and spatial subassemblages under low frequency cyclic loading were carried out. According to measuring and analyzing the deformation of each gauging point, including deformation development pattern and the ratio of the deformation of the measuring point to the total deformation at different drifts, the type of damage to the structure is clarified and the theoretical allowable deformation applicable to the actual construction design of the project are suggested. The experiment results show that four degrees of subassemblag damage includes overall integrity, mild damage, moderate damage, and severe damage, corresponding to the drift angles of 1/250, 1/65, 1/45, and 1/20 rad, respectively. The displacement values under different degrees of damage can be recommended as allowable deformation for different performance requirements. The percentage of subassemblage beam end bending displacement in the total storey displacement is the highest.
