| 摘 要： | 对一平面规则、对称,底部不等高嵌固的高层钢筋混凝土框架结构,采用SATWE程序模拟底部不等高嵌固的边界约束条件与简化后的等高嵌固的边界约束条件进行地震作用下的分析计算。结果表明,对于平面规则、对称,底部不等高嵌固的结构,将其简化为等高嵌固的边界约束条件进行分析计算,将会忽略实际结构中存在的地震扭转效应,为工程设计埋下安全隐患。

| Abstract: | By means of SATWE, analysis calculations under earthquake action were made in two simulated boundary constraint conditions for high - rise reinforced concrete frame structure which has the regular symmetric plane and is unequal - height fixed at the bottom. One boundary constraint condition is unequal - height fixed at the bottom, the other is equal - height fixed after simplified. The results show that under the simplified boundary constraint condition, the seismic torsional effect will be neglected in practical structure which has the regular symmetric plane and is unequal - height fixed at the bottom. The trouble will be hidden in safety in the engineer- ing design. |
