钢筋混凝土压弯构件P—Δ曲线分析

Analysis of P—Δ curve of steel concrete member subjected to compressing and bending

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。

According to the stress-strain curve of steer concrete and the rule of curvature distribution of the column, in order to oiler the theoretical basis of the subsequent test, the account of p-△ curve of steel concrete member subjected to compressing and bending is analysed, and the theoretical load-deformation （P-△） curve can be plotted by using MATLAB.
