钢筋混凝土矩形梁经济配筋率近似公式推导

摘要

以梁的有效高度h0为变量建立梁的造价函数,通过求解微分方程,推导了钢筋混凝土矩形截面梁的经济配筋率近似公式,公式表明,梁的经济配筋率只与材料强度有关,与梁的截面尺寸无关。%Variable to establish the cost function of the beam, the beam effective height h0 derived by solving the differential equation, reinforced concrete rectangular beam reinforcement ratio approximate formula. The formulas show that the beam reinforcement ratio only with the strength of the material related to the beam section size.
