摘要

为了研究福建省农村中近年来出现的框架—砌体水平混合结构的抗震性能,本文以一幢实际民居为原型,进行了1/2缩尺模拟地震振动台试验,测试了模型结构的动力特性及其在不同地震作用下的试验现象和动力反应。同时,利用ANSYS软件建立了有限元模型,并将试验数据与计算结果进行了对比。研究结果表明,计算结果和试验数据吻合较好,验证了有限元模型的有效性;结构砌体部分破坏方式相似于砖混结构;结构框架部分的混凝土柱顶节点易出现应力集中;结构刚心和质心不重合且二层侧移刚度显著大于一层;在地震作用下,一层结构会发生较大的位移且同时存在扭转效应,结合较差的建筑质量,该类型结构在地震中具有较大隐患。

Abstract

To study frame-masonry horizontal mixed structures appearing in rural areas of Fujian province in recent years, taking a real folk house as the prototype, shaking table tests for its 1/2 scale model were conducted, its dynamic characteristics, test phenomena and dynamic responses under different earthquakes were measured. Meanwhile, the structure’s finite element (FE) model was established with the software ANSYS. Then the elastoplastic response time-history analysis for the FE model under earthquakes was performed. The FE analysis results were compared with the shaking table test results. It was shown that the FE computing results agree well with the test ones, the effectiveness of the FE model was verified; destruction patterns of masonry part of this type structure are similar to those of brick-concrete structures; stress concentration occurs at the top node of frame part’s RC columns; the structure’s rigidity center and mass center do not coincide, the lateral stiffness of the second floor is obviously larger than that of the first one; under the action of earthquakes, the first floor has bigger displacements and torsion effects; due to poorer construction quality, there is a larger hidden danger in this type structures under earthquakes.
