摘要:随着我国社会经济的快速发展和建筑工程商品化进程的加快,人们对建筑质量和居住环境的要求也越来越高,进一步提高了建筑结构设计要求。由于建筑工程受到设计、施工环境、温度的影响,导致建筑结构产生裂缝,不仅会造成建筑物发生渗漏,还会影响建筑结构的整体性能和抗震性能。因此,防止建筑结构裂缝的产生就显得尤为重要。本文主要对建筑结构设计基本体系、建筑结构设计裂缝成因、建筑结构设计裂缝控制措施进行了分析。

Abstract:With China's rapid economic and social development and construction of commercial process accelerate, people on the building quality and living environment of increasingly high demand, further improvement of building structure design. Due to the construction project by design, construction environment, the influence of temperature, leading to the construction of the structure crack, will not only cause building leakage, will also affect the structural performance and seiic performance. Therefore, to prevent the cracks of building structure is very important. This paper focuses on the design of building structure system, building structure design, structure design of building crack crack control measures were analyzed.
