本文通过对某一砌体结构自身裂缝进行分析,确定裂缝产生的原因,为裂缝处理方案制定提供参考。全文利用大型通用有限元软件ANSYS对既有砌体进行不同温度荷载下的裂缝及侧移变形分析,通过对不同温度荷栽下的裂缝分布观察研究并与实例对比分析,得出温度荷载下的裂缝分布和结构自身裂缝分布基本一致,进而得出此砌体结构本身的裂缝为温度裂缝。此分析可应用于其他类似砌体结构分析中,并为砌体结构裂缝治理提供理论依据。
In this paper, the analysis of the cracks in a masonry structure to determine the causes of cracks, fracturing program for the development of reference. Full text The large-scale finite element software ANSYS is used to analyze the cracks and lateral deformation of existing masonry under different temperature loads. By observing and analyzing the crack distribution under different temperature loads and comparing with the examples, it is concluded that under the temperature load The crack distribution and the structure’s own crack distribution are basically the same, and then the crack of the masonry structure itself is the temperature crack. This analysis can be applied to other similar masonry structure analysis and provide a theoretical basis for masonry structure crack management.
