摘要
为研究空间框架抗震性能,设计制作了1个PEC柱–型钢梁端板连接空间框架缩尺试件,在低周往复荷载下进行试验。分析试验数据可知,其极限承载力为453.2 k N,延性系数平均值3.2,层间位移角小于规范限值,能量耗散系数在2.11~2.90之间,说明PEC柱型钢梁端板连接空间框架具有优良的抗震性能。
In order to study the seismic behavior of the 3D scale frame, this paper designed 1 PEC column steel beam end plate connection the 3D scale frame scale test samples under cyclic loading. Analysis of test data, ultimate bearing capacity is 453.2kN, average ductility coefficient is 3.2, the displacement angle between the layers is less than the norm limit, energy dissipation factor is between 2.11-2.90, the PEC column type steel beam end plate connection space frame has excellent seismic performance.
