出于对一批别墅型房屋的质量鉴定工作的总结,得出该类房屋较为普遍的弊病,诸如:楼梯间缺少构造柱,不满足现行抗震规范要求;为满足功能要求,多数进行了改扩建,但改扩建部分与原结构连接部位处理不足,成为削弱房屋整体性的问题之一;局部因功能要求导致层高超限等等。这些都是此类房屋抗震加固需要提起注意的问题,解决这些问题对实际工程具有一定的指导意义。 Out of the evaluation of the quality appraisal of a group of villa-type houses, the shortcomings of such houses are generally found, such as: the lack of structural columns in the stairwell, does not meet the requirements of the current seismic code; to meet the functional requirements, most of the expansion However, the connection between the expansion and expansion part and the original structure is not adequately dealt with, which has become one of the problems that weaken the integrity of the houses. The local requirements of the functions lead to the overrun of floors and so on. All of these are the issues that need attention in seismic strengthening of such houses. Solving these problems is of guiding significance to practical projects.
