摘　　要：以混凝土受压边缘的应变达到其极限应变作为截面的极限状态，利用截面的Ｍ－Ｎ－Φ关系，建立其平衡方程，求解ＳＲＣ（劲性钢筋混凝土）偏心受压构件截面的极限承载能力．将劲性钢筋混凝土与普通筋混凝土偏心受压构件截面承载能力的计算统一起来，避免了普通混凝土偏心受压构件截面大小偏心的判断，使计算更为简便统一．该法可用于编制劲性钢筋混凝土和普通钢筋混凝土偏心受压构件截面的承载力计算表．The ultimate bearing capacity of a section of eccentrically compressed member made of steel reinforced concrete (RSC) is solved by avoiding to judge the degree of eccentricity of a section of eccentrically compressed member made of common concrete. The author takes the strain of concrete at compressed margin approaching ultimate strain as the ultimate state of a section;and makes use of bending moment axial force curvature of a section;and makes use of bending moment-axial force curvature ( M N Φ ) relation of a section to establish its balance equation.With the purpose of unifying and simplifying the calcuation of sectional bearing capacity of eccentrically compressed members made of both SRC and RC,the methed can be used in preparing relevant calculation list.
