砖石结构是一种历史悠久而使用普遍的建筑物结构型式,尤其是在中国及第三世界国家中,普遍被采用,其优点是造价低,施工方便,材料选择性不高。但是它最大缺点是抗震性能差,已被中国近廿年来的几次大地震证明。在寻求其提高抗震能力方面,简单的方法是抗震加固。近期一些研究者寻求另一种方法,基础隔离的方式,即在原基础上,相当于防潮层 Masonry structure is a type of building structure with a long history and common use, especially in China and third world countries. The advantages are low cost, convenient construction and low material selectivity. But its biggest drawback is its poor seismic performance, which has been proven by several major earthquakes in China in recent years. In seeking to improve its seismic capability, the simple method is seismic strengthening. Some recent researchers have sought another method, the basic isolation method, that is, on the basis of the original, equivalent to the moisture barrier layer.
