一、概述为了加快多层砖房(包括底层全框架和多层内框架房屋一下同)的抗震鉴定,对于六层和六层以下、重量和刚度沿高度比较均匀的、以剪切变形为主的房屋,可以按照其抗震墙的最小面积率进行墙体的抗震强度验算。当墙体的强度不足时,可增设抗震墙体或采用水泥砂浆、钢筋网水泥砂浆、喷射混 I. Overview In order to speed up the seismic appraisal of multi-story brick buildings (including the whole bottom floor and multi-story frame houses), for the six and six floors, the weight and stiffness are more uniform along the height, mainly based on shear deformation. The house can be checked for seismic strength of the wall according to the minimum area ratio of its anti-seismic wall. When the strength of the wall is insufficient, a seismic wall may be added or cement mortar, steel mesh mortar, spray mixing
