既有建筑加固改造的风险及对策

基于目前既有建筑鉴定加固改造设计与施工风险较大的现状,从建设法律规定、强制性标准、加固改造施工等各个环节分析了出现风险的因为.提出应加强对不可抵御灾害、结构抵抗偶然作用和结构承载力评定等加固改造前鉴定项目,并给出规避建筑倒塌超载破坏的技术措施和加固改造工程施工中应当注意的问题.

Risks and Countermeasures for Reinforcement and Reconstruction of Existing Buildings

Based on the high risks in design and construction of reinforcement and reconstruction of existing buildings,the causes of the status are analyzed from construction laws,standards and construction of engineering.Thus pre-identification items are suggested such as identification of non-resistant disasters,incidental loads and structural bearing capacity.Meanwhile,the technical measures preventing destruction due to collapse and overloading and the cautions during reinforcement and reconstruction are put forw...
