减震结构非线性时程分析的研究

Research on energy dissipation-seismic reduction structure with nonlinear time history analysis

本文对减震结构(附设阻尼器的消能减震结构)进行了非线性时程分析的研究。探讨了减震结构的研究背景、国内外的研究现状、现行规范对减震结构的相关规定、减震结构在理论、实际应用上的问题和难点、减震结构的社会意义和经济效益以及对非线性时程分析进行了简要介绍。最后通过一个工程案例,对减震结构和无控结构进行了比较(柱轴力、顶点位移、层间位移角),得出了一些可以用于工程实际的结论。

This paper researched on energy dissipation - seismic reduction structure （with nonlinear viscous liquid damper） with the nonlinear time history analysis. Authors mainly discussed the research background, current research at home and aboard, the relevant provisions of the current regu-lation and standards, several problems and difficulties of the theory and its practical applications, social significance and economic benefits of the energy dissipation - seismic reduction. And take a brief introduction to the nonlinear time history analysis. At last, authors made an example of engineering to make a contrast between the original structure and the energy dissipation -seismic reduction focusing mainly on the axial force of the column, top displacement, displacement angle between layers, and get some useful conclusion which can be used in the practical engineering.
