摘要: 分析了圆截面钢管砼构件在弯曲极限状态下,钢管和砼相互作用而产生的两种套箍作用效果;推导了理想塑 性状态下的中和轴位置和极限弯矩的计算方法.

关键词: 钢管砼, 套箍作用, 极限弯矩, 中和轴

Abstract: Two efects of confinement which result from the interaction between steel tube and concrete under ultimate limit bending states are analyzed.In addition,the calculation method of zero line position is deduced as well as the computational formula of limit bending moment under ideal elasto plasticity states.

Key words: effect of confinement, ultimate limit bending moment, zero line
