【摘要】 根据钢筋混凝土的应力应变关系和压弯构件曲率分布规律,分析了钢筋混凝土压弯构件P—Δ曲线的计算过程,并用MATLAB绘制了荷载—挠度(P—Δ)的曲线,为后续试验部分提供了理论分析的依据。更多还原

【Abstract】 According to the stress-strain curve of steer concrete and the rule of curvature distribution of the column,in order to offer the theoretical basis of the subsequent test,the account of P—Δ curve of steel concrete member subjected to compressing and bending is analysed,and the theoretical load-deformation(P—Δ) curve can be plotted by using MATLAB.更多还原
