The computer simulation and testing research for flexural properties of arc-shaped brick wall

在研究国内外砌体结构理论的基础上,阐述了关于弧形砖墙这种特殊结构形式墙体的结构性能研究的必要性和重要性,并提出了适合弧形砖墙结构基本力学性能研究的计算机数值模拟方法及结构静力试验方法,总结出了弧形砖墙在背心倾覆力作用下的结构基本力学性能及其破坏机理、裂缝开展情况。结果表明,弧形砖墙抵抗背心倾覆力作用的能力优于直线段墙。

This paper is based on domestic and overseas researches on masonry structure theory. It expounds the necessity and importance of study on the structure and mechanical properties of arc-shaped brick wall. Additionally, it also raises methods including the computer simulation and structure static load test. It makes a summary of the structure and mechanical properties, failure mechanism and cracking process concerning the arc-shaped brick wall under the centrifugal force. The conclusion proves that the centrifugal overturning resistant competence of arc - shaped brick wall is better than that of the linear wall.
