中文摘要：

大量震害表明，框架结构节点特别是角节点表现出较为明显的空间受力耦合作用。目前，国内外对于梁柱节点的试验研究成果主要集中于平面节点，对于空间节点的研究较为匮乏，试验方法也没有统一标准。本文以6个3D组合节点的试验为基础，从约束条件、试验装置、加载模式、测点布置及量测方法等方面对空间节点抗震性能试验的几点关键问题进行了探讨和研究，为今后类似的空间节点试验提供了参考。

英文摘要：

The beam-column joints in frames have shown coupling effects under bi-directional load in earthquakes. In previous studies, most of the beam-column joint specimens were taken from a part of plane frame, and the tests on 3 D joints were very limited. In this paper, a series of tests on 3 D composite joints were proposed to study the seismic performance under bi-directional load, and the boundary conditions, test facility, loading paths and measurements were introduced.
