在房屋建筑工程中,钢筋混凝土结构是最常见的建筑结构类型。从房屋结构方面看,其重点在于抗震设计。在发生地震的情况下,建筑物在经过简修或者不修的情况下仍然可以居住。而在遇到强烈的地震的时,能够尽量减少房屋结构的倒塌,这是进行抗震设计的目标。本文分析了钢筋缓凝土结构在地震时的变形能力指标,同时对房屋不同部位的容许变形值进行了分析,希望能够促进建筑行业的发展进步。 In the housing construction, reinforced concrete structures are the most common type of building structure. From the perspective of housing structure, the emphasis is on seismic design. In the event of an earthquake, the building can still be settled with little or no repair. In the face of a strong earthquake, it can minimize the collapse of the house structure, which is the goal of seismic design. In this paper, the indexes of deformation capacity of reinforced concrete structure during earthquake are analyzed. At the same time, the allowable deformation values ​​of different parts of houses are analyzed, hoping to promote the development of the construction industry.
