异形板力学性能分析及钢筋配置优化

Mechanical properties analysis of Special-shaped plate and Reinforced configuration optimization

由于追求简洁的室内空间及自由布局,越来越多的异形板出现在住宅设计中,而异形板的受力及变形性能一直是结构设计人员关注的重点,掌握异形板的应力及裂缝分布规律有利于设计人员对异形板进行钢筋配置优化。结合工程实例采用理正结构设计工具箱与ansys14.0对B1、B2两种异形板的力学性能进行有限元分析,将两种有限元分析结果对比得出异形板应力集中于截面突变处,适当增加放射状附加受力钢筋及暗梁可以保证异形板的安全。

Due to the simplicity of interior space and free layout , more and more special - shaped plates were appeared in residential de- sign, the Stress and deformation performance of special - shaped plates were focused on structure designers, mastering the stress and crack distribution of special - shaped plates were conducived to reinforced configuration optimization. The mechanics properties of B1 and B2 spe- cial - shaped plates were analysed by lizheng structural design toolbox and ansys 14. 0, by contrast with two kinds of analysis results, the stress of special - shaped plates focusing on the Cross - section mutation place was obtained. The security of special - shaped plates were protected by increasing radial reinforcement and setting dark beam.
