摘要
考虑土与上部结构共同作用更加符合工程实际。本文运用ANSYS软件对一双塔楼连体结构建立了考虑土体参与共同作用和不考虑土体共同作用的三维模型。分析结果表明,考虑共同作用后,结构周期变长,地震反应更为强烈,偏于不安全,不容忽视。
The fact of engineering is in accordance with the consideration of the dynamic soil-structure interaction. By contrast with the common one, the model with the dynamic soil-structure interaction of a double-tower connecting structure is founded by ANSYS program in this paper. The results illustrate the periods of the structure are longer, and its seismic response is more intense. The effect which is caused by the dynamic soil-structure interaction can＇t be ignored because of its fatalness.
