45° lateral

Through theoretic and finite element analyses on 45 degree oblique cracks of cast-in-situ floor-slab of masonry buildings,we were convinced that the main factors of oblique cracks situated in 45 degree location are temperature difference and concrete shrinkage also.

针对目前混合结构房屋现浇混凝土楼板中大量出现的45°斜裂缝进行了理论分析和有限元分析,证实了斜裂缝分布在45°区域的主要原因除了温差之外,还有混凝土的收缩,并提出有效的控制建议。
