摘要
文章利用双剪屈服准则1导出了钢筋砼薄板屈服时屈服条件,并利用此屈服条件创立了用机动法计算薄板极限载荷的新的塑性铰线理论,它与用原有塑性铰理论所计算的结果比较,更符合实验结果〔2-4〕。
The yield conditions of reinforced concrete plates have been derived employing the twin shear stress yield criteria. Based on the yield criteria a new theory of the plastic hinged lines for the limit load calculation of reinforced concrete plates. The calculation outcome resulting from the theory is in accordance with the experiment findings compared with the previous theory.
