[摘要] 提出了一种考虑轴向、弯曲和剪切共同作用的基于纤维模型有限单元柔度法的梁柱单元模型，采用修正斜压场理论(MCFT)模拟混凝土纤维在压弯剪共同作用下的双轴受力性能。通过与试验结果的对比，验证了模型的有效性。

Abstract: The secant flexibility-based fiber element with combined flexure and shear was presented. In this model, modified compression field theory was utilized to simulate bi-axial behavior of concrete in each subdivided concrete layered strip. Effectiveness of this method was verified by calibrating the analytical results with those of test.
Keywords: fiber element; reinforced concrete; shear
