多层砖砌房屋是目前我国应用较广泛的一类建筑。这类建筑是用砖块和砂浆砌筑而成的,这些建筑材料的脆性决定了砖砌体的延性差,抗剪、抗拉及抗弯强度很低。因此,砖砌房屋的抗震能力较差,如果没有合格的抗震设计和较好的施工质量,在强烈的地震力作用下,墙体很容易产生开裂或倒塌,破坏率 Multi-storey brick buildings are widely used in China today. This kind of building is made of bricks and mortar. The brittleness of these building materials determines the poor ductility of brick masonry and the low shear, tensile and flexural strength. Therefore, brick-built houses are poor in earthquake resistance. If there is no qualified seismic design and good construction quality, under strong seismic forces, the wall will easily crack or collapse, and the destruction rate will be high.
