［摘要］從鋼筋混凝土正截面承載能力計算時的平截面假定，不考慮混凝土的抗拉強度，鋼筋應(yīng)力-應(yīng)變關(guān)系為理想彈塑性模型的基本假定出發(fā)，建立了任意形狀截面各種應(yīng)力圖形的函數(shù)表達式。利用數(shù)學和力學方法，推導出計算鋼筋混凝土任意形狀截面構(gòu)件截面延性系數(shù)的數(shù)學表達式，并給出了鋼筋混凝土任意形狀截面構(gòu)件在外力作用下截面應(yīng)力圖形形狀的判別式。
［關(guān)鍵詞］鋼筋混凝土； 任意形狀截面； 延性系數(shù)

Abstract:Based on the assumption that the reinforced concrete cross-section is plane when calculated without considering concrete tensile strength and the assumption that reinforcement stress-strain relationship is ideal elastic-plastic deformation, A function expression of stress pattern in any shape section that has a symmetry axis was built. By using mathematical and mechanics method, a mathematical expression of reinforced concrete member section elongation coefficient in any shape section that has a symmetry axis was deduced, and a discriminant of reinforced concrete section stress graphics shape under action of outside forces in any shape section that has a symmetry axis was expressed.
Keywords:reinforced conncerete; arbitraty shape section; ductile coefficient
