理论分析本文所用的有限元分析的模型与墙体的尺寸示于图1和表1。把墙和其它构件划分为矩形单元,其中柱单元尺寸的确定原则,应使柱得到均匀的应力分布。各种材料的性能列于表2。把钢筋作为线性元处 Theoretical Analysis The finite element analysis model used in this paper and the dimensions of the wall are shown in Figure 1 and Table 1. The wall and other components are divided into rectangular elements, in which the principle of determining the dimensions of the column elements should give uniform stress distribution to the columns. The properties of various materials are listed in Table 2. Take rebar as a linear element
