【摘要】：框架填充墙结构具有施工方便、空间布置灵活和室内空间大等优点，在建筑工程领域是一种广泛使用的结构形式。虽然框架填充墙有很多优点，但是已发生的地震灾害现象表明填充墙的破坏依然很严重，传统的设计方法及施工模式已经很难满足现代建筑的抗震要求，框架填充墙结构在强震中的破坏已造成重大的人员伤亡和财产损失，引起了各国相关研究机构和设计人员的高度重视。虽然我国设计规范提出砌体填充墙与钢筋混凝土框架之间，宜脱开或采用柔性连接，但并没有给出明确的构造方法，在施工上具有很大随意性。为了合理提出框架与填充墙之间的可靠连接方式，必须先研究框架与填充墙之间的相互作用，使得框架主体与填充墙构件之间有利的相互作用得到充分发挥，而不利的相互作用得以避免，最大程度的提高结构整体抗震能力。通过对比分析普通纯框架体系和框架填充墙结构体系的抗震行为，在已有的研究成果基础上，本文阐述了在水平地震作用下墙体与框架结构之间的相互影响，，包括填充墙对框架的有利和不利影响，以及框架对填充墙的约束效应，提高了填充墙的变形能力和抵抗荷载的能力。根据填充墙在地震中的破坏情况和框架与填充墙之间的相互作用，为防止结构的破坏，框架与填充墙之间的连接方式最为关键，同时对提高框架填充墙整体的抗震性能也有一定的研究价值。本文提出了带阻尼装置的框架填充墙，利用有限元分析软件ABAQUS进行模拟，通过对比分析纯框架、普通框架填充墙和带阻尼装置的框架填充墙三种不同结构组成在低周反复荷载作用下的受力性能，得出以下结论：普通框架填充墙与纯框架相比，普通框架填充墙的承载能力较纯框架要有所提高，而耗能能力比纯框架的要差；带阻尼装置的框架填充墙与普通框架填充墙相比，前者的承载能力和耗能能力都有不同程度的提高，说明此构造措施有助于提高结构的抗震能力，具有一定的应用价值和开发前景。
[Abstract]:The frame infilled wall structure has the advantages of convenient construction, flexible space arrangement and large indoor space. It is a widely used structure form in the field of building engineering. Although the frame infilled wall has many advantages, but the earthquake disaster phenomenon has occurred, the damage of the infilled wall is still very serious, the traditional design method and construction mode have been difficult to meet the seismic requirements of modern buildings. The damage of frame infilled wall structure in strong earthquake has caused heavy casualties and property losses, which has attracted great attention of relevant research institutions and designers in various countries. Although the design code of our country suggests that the masonry infilled wall and reinforced concrete frame should be removed or flexible connection is suitable, but there is no clear construction method, which is very random in construction. In order to reasonably propose a reliable connection between the frame and the infilled wall, we must first study the interaction between the frame and the infilled wall, so that the beneficial interaction between the frame body and the infilled wall member can be brought into full play. Adverse interactions can be avoided and the overall seismic capacity of the structure can be maximized. By comparing and analyzing the seismic behavior of ordinary pure frame system and frame filled wall structure system, based on the existing research results, this paper expounds the interaction between wall and frame structure under horizontal earthquake. The advantages and disadvantages of the infilled wall on the frame and the constraint effect of the frame on the infilled wall can improve the deformation capacity and the ability of resisting load of the infilled wall. According to the failure situation of infilled wall in earthquake and the interaction between frame and infilled wall, in order to prevent the damage of structure, the connection between frame and infilled wall is the most important. At the same time, it has certain research value to improve the seismic performance of frame infilled wall. In this paper, the frame infilled wall with damping device is proposed, and the finite element analysis software ABAQUS is used to simulate it, and the pure frame is compared and analyzed. The mechanical behavior of common frame infilled wall and frame infilled wall with damping device under low cyclic cyclic loading is obtained. The following conclusions are drawn: compared with pure frame, the common frame infilled wall is different from pure frame. The load-carrying capacity of the ordinary frame infilled wall is higher than that of the pure frame, but the energy dissipation capacity is worse than that of the pure frame, and the frame infill wall with damping device is compared with the ordinary frame infill wall. The load-carrying capacity and energy dissipation capacity of the former have been improved to some extent, which indicates that this structural measure is helpful to improve the seismic capacity of the structure, and has certain application value and development prospect.
