无筋砌体墙抗剪性能有限元分析
|
摘要
通过对不同高宽比无筋砌体墙破坏形态和应力分布进行有限元分析,研究高宽比对无筋砌体墙抗剪性能的影响。计算结果表明,高宽比对砌体墙抗剪性能影响较大,随高宽比的增大,墙体破坏形态由剪切破坏转为弯曲破坏,且抗侧承载力明显下降。
Various forms of damage and the stress distribution on the different ratio of height to width of unreinforced masonry wall were analyzed through the material nonlinear FE analysis,the effect of the shear behavior was discussed due to the different ratio of height to width of the wall.The results show that the ratio of height to width greatly impacts the shear strength of the wall.With the ratio of height to width increasing,the failure mode of the wall is transformed from shear failure to bending failure,and the anti-capacity greatly decreased.
