在取截面开裂瞬间受压区应力图形为三角形,受拉区为梯形的前提下,本文对任意截面抵抗矩塑性系数γ值提出了简化计算方法,并据此列出了便于实用的γ值表。与现行规范和有关文献的γ值表相比,本文的值表具有更广泛的适用性。 At the instant of cracking of the section, the stress pattern of the compression zone is triangular and the tension zone is trapezoidal. On the premise of a trapezoidal trapezoidal section, this paper proposes a simplified calculation method for resisting moment plasticity coefficient γ value for any section, and lists the convenient and practical γ value table accordingly. . Compared with the gamma table of the current specification and related literature, the value table of this paper has more extensive applicability.
