隐形密框复合墙体结构的框格优化

摘要

基于非线性分析程序 ABAQUS, 对隐形密框复合墙体中隐形密框的轴压受力过程进行了数值分析, 利用验证后的模型对隐形密框中的框格进行优化, 分析了参数包括框格的高宽比和肋柱尺寸.结果表明: 肋柱是墙体的主要受力构件; 肋柱总截面面积不变时, 每个肋柱直径为49 mm 时, 密框结构轴压承载力最高, 延性最大.%Based on the finite element analysis software ABAQUS, the failure process of the invisible multi-ribbed frame is simulated under axial loading, and the frame is optimized by using the verified model, then the height width ratio of the frame and size of the ribbed column are analyzed. The results show that the ribbed columns bear the most axial compressive force, when the total section area of the ribbed columns is unchanged, the invisible multi-ribbed frame wall with the ribbed columns of the diameter of 49 mm have the highest axial compressive bearing capacity and the maximum ductility.
