以Hencky中厚板理论为基础 ,采用理想弹塑性单元模型 ,对柱下钢筋混凝土独立基础进行了非线性分析。讨论塑性铰线的分布规律 ,对我国地基基础设计规范中的有关抗弯设计方法提出修正建议。
On the basis of Hencky plate theory, a non-linear analysis of the independent foundation of reinforced concrete under column is carried out by using the ideal elastoplastic element model. Discusses the distribution rule of plastic hinge line, and puts forward some corrections to the relevant bending design methods in China’s foundation design code.
