老旧小区阳台的鉴定及加固改造分析

Identification and Reinforcement and Renovation Analysis on the Balcony of the Old Residential

以某装配式大板结构为例,在原结构存在缺陷以及需要增设静力荷载的双重技术难题条件下,从检测、鉴定和加固3个角度出发,分析结构中存在问题,并采用增加截面法和改变结构体系的方法对该建筑进行加固处理,使建筑满足安全性和使用性要求。

Based on the actual case of an assembled plate structure,under the condition of the defects of the original structure and the dual technical problems that need to be added to the static load,this paper sets out from the three angles of detection,appraisal and reinforcement.The existing problems in the structure are analyzed,and the method of adding cross section and changing the structure system are adopted to reinforce the building,so that the building can meet the requirements of safety and serviceability.
