| 摘 要： | 大剪跨比密肋复合墙体处于弯矩和剪力共同作用的受力状态,墙体的整体弯曲作用造成其破坏形式主要为压弯破坏.依据作者前期完成的密肋复合墙体压弯剪复合受力性能试验研究及有限元分析成果,对墙体极限压弯承载力的组成及各构件对压弯承载力的贡献进行了具有一定精度的定量分析,按照安全、方便、实用的原则对计算公式进行了简化,提出了满足工程精度要求且方便计算的压弯墙体正截面承载力设计实用计算公式.

| Abstract: | Multi-ribbed composite wall of lager shear-span ratio is under co-action of moment and shear.The main failure forms caused by whole bend ofthe wall is press-bend failure.The composition of press-bending limit bearing capacity and contribution of the every components for bearing capacity was analyzed quantitatively based on the research results of the test and finite element analysis on the hybrid behaviors of the wall under compression,bending and shear,finished in earlier stage.The calculation formula was ... |
