预制混凝土结构的抗震性能是影响其在抗震设防地区推广应用的关键因素。拟动力试验就是将计算机系统与电液伺服加载系统联机进行的加载试验,该试验方法能够比较合理地再现地震动输入下建筑结构的地震响应,并可进行大尺度或足尺结构模型的试验,是目前进行预制混凝土结构抗震性能试验研究的有效方法之一。为此,简要介绍了拟动力试验方法及子结构拟动力试验技术,重点阐述了预制混凝土框架结构和剪力墙结构的拟动力试验研究现状及进展,并对今后预制混凝土结构的拟动力试验研究提出了建议。
The seismic performance of prefabricated concrete structures is a key factor that affects its popularization and application in earthquake-resistant fortification areas. The quasi-dynamic test is a loading test that connects the computer system with the electro-hydraulic servo loading system online. The test method can reasonably reproduce the seismic response of the building structure under the input of ground motion and can test the large-scale or full-scale structural model, It is one of the effective methods to test the seismic performance of precast concrete structures. In this paper, the pseudo-dynamic test method and pseudo-dynamic test technology of sub-structure are briefly introduced. The status quo and development of pseudo-dynamic testing of precast concrete frame structure and shear wall structure are emphatically elaborated. The future pseudo-dynamic test of precast concrete structure give suggestions.
