摘要
装配式混凝土结构是未来建筑业的重要发展趋势之一,其所具有的各种优质特性也使得人们对其的接受性越来越高。目前我国已经建造了一定数量装配式结构建筑并投入使用。为了分析装配式典型框架节点的抗震性能,文章应用ANSYS有限元软件对现在实际工程应用的装配式框架梁-柱-叠合板节点进行数值仿真分析,分析结果与实验数据的对比,证实采用的仿真方法可靠。在此基础上,对节点分别进行变更参数有限元分析,研究假想参数变化对其抗震性能产生的影响。分析结果表明:装配整框架节点具有良好的抗震性能,轴压比对装配式框架节点耗能能力的影响较小,混凝土等级的变化对节点耗能能力具有一定的影响。
Assembled concrete structure is one of the important development trends of the future construction industry,and its various high-quality characteristics make people accept it more and more.At present,China has built a certain number of fabricated structural buildings and put them into use.In order to analyze the seismic performance of the assembled typical frame joints,this paper applies ANSYS finite element software to numerically simulate the assembled frame beam-column-stacked plate joints of practical engineering applications.The comparison between the analytical results and the experimental data confirms the use of this paper.The simulation method is reliable.On this basis,the finite element analysis of the change parameters is carried out on the nodes to study the influence of the hypothetical parameter changes on the seismic performance.The analysis results show that the assembled frame joints have good seismic performance,and the axial compression ratio has little effect on the energy consumption capacity of the fabricated frame joints.The change of concrete grade has certain influence on the energy consumption capacity of the nodes.
