【摘要】 本文研究了钢筋混凝土板固定角（α２）、裂缝开展角（α＇）、转动角（α）和钢筋角（αｓ）之间的关系，建立了钢筋混凝土板的平衡方程、协调方程以及钢筋和混凝土的本构方程，提出了钢筋混凝土板裂缝开展角的计算方法．通过两块板的计算结果与试验结果的比较，本文提出ｒ计算方法的可靠性得到了验证．更多还原

【Abstract】 This paper is concerned with the relationship among fixed angle (α2 ), crack growth angle (α’), rotating angle (α) and steel angle (αs ) of reinforced concrete plates. Based on the equilibrium equations, compatibility equations of reinforced concrete plates and the constitutive equations of steel and concrete, a calculation method for the crack growth angle of reinforced concrete plates is proposed. The reliability of the method is verified by comparing the calculation results with the test results of the two plates.更多还原
