Evaluation and Treatment of Structure Cracks in Long-Term Buildings
Through the analysis of the data from the Building Quality(Safety)Inspection and Identification Reports of different eras,this paper attempts to analyze the various states of cracks that exist on buildings after long-term service,and to evaluate their causes,properties,and degrees of harm.After comprehensive analysis,this paper believes that the cracks exposed on buildings after long-term use are the superposition of multiple factors,not caused by a single factor.Among them,the inherent deterioration of building materials represented by concrete is just one of the reasons,and the cracks caused by other factors are mainly attributed to durability cracks.Most of these cracks are"ordinary cracks",and a few are"serious cracks".This paper discusses the relevant treatment methods.
