以哈尔滨某高校20世纪50年代建造的木屋盖结构建筑为例,在分析其残损形式的基础上,提出加固改造的具体方法;并借助有限元分析方法,对结构的承载力进行重新校核。通过分析和校核结构的受力情况,找出结构的受力薄弱位置并及时加固,为类似的改造加固工程提供借鉴。 Taking a wooden roof construction built in a university in the 1950s in Harbin for example, based on the analysis of the damaged forms, a concrete method of reinforcement and reconstruction was put forward. The bearing capacity of the structure was re-checked by means of finite element analysis. By analyzing and checking the force of the structure, we can find out the weak position of the structure and reinforce it in time, which can provide reference for similar reconstruction and reinforcement projects.
