Analysis of seismic performance parameter of precast assembled damping wall frame structure

为研究装配式拼装型减震墙板框架结构的抗震性能及其影响参数和规律,基于初步试验数据和ABAQUS软件平台建立了试验试件的精细化模型。在验证了有限元建模合理性的基础上,研究了不同减震层摩擦系数、墙板强度、墙板厚度、轴压比对结构整体承载力和耗能能力等抗震性能的影响及规律。研究结果表明:增大减震层摩擦系数,可显著提升结构的整体承载力和耗能能力;增大墙板强度,可在一定程度上增强结构在小震、中震作用下的耗能效果;改变墙板厚度对结构整体承载力和耗能能力几乎没有影响;增大结构轴压比,可显著增强结构的耗能能力。

In order to study the seismic performance and its influence parameters and rules of precast assembled damping wall frame structure,the fine model of the test specimen was established based on the preliminary test data and the ABAQUS software platform. On the basis of verifying the rationality of finite element modeling,the effects of the different friction coefficient of the damping layer,the different strength,thickness of wall,the different axial compression ratio on theon seismic performance such asthe overall bearing capacity and energy dissipation capacity of the structure were studied. The result of research indicates that,increasing the friction coefficient of the damping layer of the structure can significantly improve the overall bearing capacity and energy dissipation capacity of the structure; increasing the strength of the wall can enhance the energy dissipation capacity of the structure under the action of small and moderate earthquakes to a certain extent; changing the thickness of the wall has little effect on the overall bearing capacity and energy dissipation capacity of the structure; increasing the axial compression ratio of the structure can significantly increase the energy dissipation capacity of the structure.
