进行了非工程轴方向受力(与工程轴成45°和135°方向)的带暗支撑短肢剪力墙抗震静力试验研究,通过非工程轴方向受力的4个1/2缩尺的L形短肢剪力墙抗震性能试验,分析比较了主要抗震性能指标,并对其内在抗震机理进行了研究.试验表明,在非工程轴方向受力情况下,加设暗支撑可显著提高短肢剪力墙的抗震能力.
In this paper, seismic static experimental research on short pier shear walls with concealed bracings without being subjected to engineering axial force (45° and 135° with engineering axes) is conducted. By the systemic experiments on four 1/2 scale L-shaped short pier shear walls with concealed bracings without being subjected to engineering axial force, the main seismic performance indexes of L-shaped short pier shear walls without being subjected to engineering axial force are discussed, and the immanent seismic mechanism is investigated. It shows that concealed bracings improve remarkably the seismic performance of short pier shear walls without being subjected to engineering axial force.
