结构抗震试验方法的发展

Advances in the dynamic testing method of structures

地震荷载极大的破坏性,使得结构抗震性能的研究成为一个被广泛关注的热点问题。为了提高结构抗震研究的试验能力和试验水平,近年来在传统结构抗震试验方法的基础上,出现了一些新的试验方式和方法。本文总结介绍了目前结构抗震试验方法的一些发展趋势,包括:(1)地震模拟振动台的大型化和多台化,以进行大比例模型甚至足尺模型试验或考虑大跨度结构地震动的非均匀性;(2)进行子结构试验的实时化,以实现数值子结构模型和试验子结构模型的实时结合;(3)进行试验设备的网络化,以提高试验设备的利用率,实现资源共享等,供有关研究者参考。

The tremendous destruction of the earthquake load makes the seismic research of structures become a subject extensively concerned. To improve the ability and the accuracy of the dynamic test of structures, some new dynamic test means were developed on the basis of the traditional test methods in the recent years. In the paper, the advances was introduced in the full-scaled shaking table, the multiple shaking tables, the real-time substructure testing, and the network for the seismic testing equipments. Moreover, several tendencies of the dynamic testing development of structures are suggested. The paper can be a reference for the seismic investigation of structures.
