基础滑移隔震房屋结构设计与工程应用的理论研究

本文进行了隔震体系限位耗能元件的弹塑性分析，利用多层砖房的足尺结构进行了滑移结构动力特性试验。通过对隔震房屋有限位装置的恢复力特性的研究，提出了多层砖房隔震结构的恢复力计算模型，编制了隔震结构的分析程序，提出了基础滑移隔震房屋结构设计的构造措施和减震效果试推检验方法。实际工程算例表明，滑移隔震结构较基础固定结构有较好的抗震性能，在设计中可降低设计烈度二度进行隔震设计。

Theoretical Study on Design and Application on Sliding Base Isolation Structure

The elsto-plastic analysis on the member of resilient derice in sliding base isolation system is given.The dynamic tests on full-sale brick masonry structure models with and without sliding base isolation are carried out.Through the study on characteristic of restoring force of isolation system with resilient device,the calculation model of restoring force of brick masonry structure with sliding base isolation is proposed,with which an analytical program of isolation system is compiled.The construction methods for device of isolation structure and test effect of isolation base are presented.The result of the application of sliding isolation in practical engineering shows that the sliding base isolation structure is better than the fixed base structure in aseismic behavior.In aseismic design of sliding base structure,the isolation device may be designed in accordance with that the demanded anti-earthquake intensity may be reduccd by two degrees.
