摘要
针对钢筋混凝土桥墩压弯承载力的计算 ,提出了基于极限状态的截面应力应变关系 ,并分别以等效矩形应力图和混凝土应力应变公式处理受压区混凝土的抗力计算图式 ,将轴压压弯纯弯的计算方法统一起来 ,使计算更简捷 ,最后给出工程应用实例 .
A unified calculation method is derived to evaluate the axial and bending bearing capacity of RC (reinforced concrete) piers. In derivation, the equivalent rectangular-stress graph and the stress-strain formula are respectively adopted, corresponding to the stress-strain relation for limited state. The method presented in this paper is applicable for calculating the bearing capacity of axial compression, compression-bending, and pure bending as well. An engineering example is given at the end of the paper.
