新加坡的大多数建筑都是轻钢筋混凝土结构，主要是为重力荷载而设计的，因为新加坡是一个位于中低地震区的岛国。采用实验和数值方法研究了具有狭长矩形平面图的典型高层住宅建筑的动态特性。详细讨论了砖填充墙和柔性隔板对建筑物动态特性的影响。环境振动测试的结果与具有不同复杂程度的三个不同有限元模型的数值结果相关。它们包括裸框架模型、带有砖填充墙的框架模型以及带有砖填充墙和柔性隔板的框架模型。第三个模型的动态特性在固有频率和振型方面与测量结果非常匹配。相关结果证明了砖填充墙和柔性隔板对窄矩形建筑结构动力特性的各自影响。版权所有 © 2006 约翰·威利父子有限公司
Most buildings in Singapore are lightly reinforced concrete structures, which are mainly designed for gravity loading only, because Singapore is an island country located in a low‐to‐moderate seismic region. The dynamic properties of a typical high‐rise residential building with a long, narrow rectangular floor plan are studied using both experimental and numerical methods. The effects of the brick infill walls and the flexible diaphragms on the dynamic characteristics of the building are discussed in detail. The results from the ambient vibration tests are correlated with the numerical results of three different finite element models with different levels of sophistication. They include a bare frame model, a frame model with brick infill walls, and a frame model with both brick infill walls and flexible diaphragms. The dynamic properties of the third model match very well with the measured results in terms of both the natural frequencies and the mode shapes. The correlation results demonstrate the respective effects of the brick infill walls and the flexible diaphragms on the dynamic characteristics of the narrow‐rectangle building structure.
