| 摘 要： | 为研究宗教建筑震后加固改造技术,基于对改造施工中的青城山上清宫居士楼进行的实地调查,采用有限元法,考虑边界非线性的影响,建立了数值分析模型,在此基础上对其自振特性进行了分析,结果与规范公式基本一致.此外,基于瞬态动力分析方法,对改造前、后的结构变形、基底剪力和构件内力响应进行了分析.研究表明,柔性边界可以较好地协调砖木结构的受力变形,形成刚柔相济的结构体系,提高结构抗震能力.

| Abstract: | An investigation was carried out on the Jushi building being retrofitted in the Shangqing Temple on the Qingcheng Mountain in order to research the retrofitting measures of religious buildings.The FEM(finite element method) was adopted to set up the numerical model of this ancient building by taking the nonlinear boundary into account.The self-vibrating behavior of the structure was analyzed to prove the validity of the numerical model.The deformation,base shear and internal force of its members before and ... |
