摘要
介绍了在负弯矩作用下钢—混凝土连续梁的特点,在理论分析的基础上,阐述了塑性中和轴位于钢梁上翼缘内和钢梁腹板内的两种情况,并给出在这两种情况下正截面的受弯承载力公式。
Characteristics of steel-concrete composite beam under the action of negative moment are introduced. Based upon theoretical analysis the formulas for bending beating capacity calculation of right section are derived under the two situations that inelastic neutral axis lies in flange and web plate.
