砖砌体延性差,抗剪、抗拉、抗扭强度低,在地震中砖结构房屋破坏比率都比较高。从长远观点看,砖砌体在地震区应该淘汰,但目前要取消它是不可能的,而且在一定时期内还将广泛地采用。因此,从各方面设法提高砖结构房屋的抗震性能还是很有必要的。从历次地震砖结构房屋破坏情况看,由于场地选择不当、设计不合理、施工不精心等因素,往往引起房屋严重破坏。但究其根 Brickworks have poor ductility, low shear, tensile, and torsional strengths. The damage ratio of brick-framed houses during earthquakes is relatively high. From a long-term perspective, brick masonry should be phased out in the earthquake zone, but it is impossible to cancel it now, and it will be widely adopted in a certain period of time. Therefore, it is necessary to try to improve the seismic performance of brick-structured houses in all aspects. Judging from the destruction of earthquake-damaged buildings in previous earthquakes, due to factors such as improper site selection, unreasonable design, and unskillful construction, they often cause serious damage to the houses. But its roots
