将任意形状钢筋混凝土薄壁截面划分成适当数目的薄壁直边，通过建立薄壁边截面的面内弯矩及轴力与相应变形之间的切线刚度关系合成了整个截面的双轴压弯恢复力模型。该模型可作为钢筋混凝土高层及高耸结构空间弹塑性地震反应分析的本构关系。
The thin-walled section of an arbitrary shape reinforced concrete is divided into an appropriate number of thin-walled straight edges. The biaxial bending of the entire section is created by establishing the in-plane bending moment of the thin-walled section and the tangential stiffness relationship between the axial force and the corresponding deformation. Resilience model. This model can be used as a constitutive relation for elasto-plastic seismic response analysis of high-rise and high-rise structures in reinforced concrete.
