当我们研究被地震摧残过的众多废弃建筑时,会发现,有些二、三层的民用住房并没有震倒,而是其上面的阁楼、水箱、女儿墙或者加高的楼层发生了坍塌,并且不同楼层的房屋其损害的程度有所不同。那么对于同一标准修筑的二层、三层民用住房,其顶部的受力情况会呈怎样的变化趋势呢?本文以一实例结合结构动力学的计算结果给予解释。 When we look at the many abandoned buildings destroyed by the earthquake, we find that some of the second and third floors of residential buildings have not been knocked down, but the loft, the water tank, the wall of the daughter, or the raised floor collapsed, and Houses on different floors have different levels of damage. So for the same standard built two-story, three-story residential buildings, the top of the force situation will be what kind of trend? This article is an example combined with structural dynamics calculations are explained.
