为研究基于相变技术的夹芯剪力墙的力学性能,采用有限元软件ABAQUS对其进行了非线性模拟,重点分析了轴压比和混凝土板厚度对其侧向承载力和协同工作性能的影响规律.同时利用EnergyPlus数值模拟软件探究了气候类型、相变层厚度和混凝土板厚度对相变材料调温节能能力的影响.结果表明:在小轴压比下,夹芯剪力墙的侧向承载力随着轴压比的增加而增加,其内侧混凝土厚度对其侧向承载力影响较大;夹芯剪力墙两侧混凝土层能够很好地协同工作.并且得到了相变材料调温和节能最优组合.“,”In order to study the mechanical behavior of sandwich shear wall based on phase change technology,nonlinear finite element software ABAQUS is adopted to analyze the effect of different axial pressure ratios and thicknesses of concrete slab on the lateral bearing capacity and cooperative working performance.At the same time,the influences of climate types,thickness of phase change layer and thickness of concrete slab on the energy-saving ability and temperature control ability of phase change materials are analyzed by using numerical simulation software EnergyPlus.The results show that the lateral bearing capacity of sandwich shear wall increases with the increase of axial pressure ratio under small axial pressue ratios;and the thickness of inner concrete has a great impact on the lateral bearing capacity;the two concrete wallpanels can work well.And the optimum combination of temperature control and energy-saving is obtained.
