摘要
针对影响混凝土多孔砖砌体结构的温度裂缝问题进行了探讨,对混凝土多孔砖砌体结构在温度荷载作用下的变形规律及应力分布规律进行了有限元分析。针对影响混凝土多孔砖砌体结构温度裂缝的几种重要因素,建立不同的有限元模型进行了非线性分析,并给出了控制及预防混凝土多孔砖砌体结构温度裂缝的若干措施。
Temperature cracks and some cracking mechanisms of concrete perforated brick masonry are discussed. Finite element analysis is done for overall structure under temperature load in order to research the rules of deformation and stress distribution under temperature difference. According different influence factors, some different finite element analysis models are established and different influence factors of temperature cracks are analyzed. Based on finite element analysis and references, some effective measures to prevent and control cracks on concrete perforated brick masonry buildings are put forward.
