多层砖房的抗震性能是较差的。在历次六级以上的地震中都发生严重破坏,造成局部倒塌甚至全部倒塌。为什么多层砖房的抗震能力差呢?怎样才能提高它的抗震能力呢?这是大家所关心的问题。要了解房屋的抗震性能,需要从两个方面来考虑;一是地震对房屋的作用,二是房屋的强度、变 The seismic performance of multi-story brick houses is poor. Severe damage occurred in all the earthquakes above the sixth level and caused local collapse or even collapsed. Why is the seismic capacity of a multi-story brick house poor? How can we improve its seismic capacity? This is a matter of concern to everyone. To understand the anti-seismic properties of houses, we need to consider two aspects: one is the effect of earthquakes on houses, and the other is the strength and changes of houses.
