To master the mechanical property and to analyze pilot project of the fiber plasterboard filled with reinforced concrete（Rapid Wall）, according to the material characteristic and the idea of micro-and macro-model, a macro-model basing on the idea of fiber model is put forward, which is applied to analyze nonlinear characteristic of composite wall. The macro model is composed of macro fiber element that only resists axis force and moment of the composite wall, and macro shear element that only resists shear force of the composite wall. Stiffness matrix of the model and constitutive models of element stiffness are presented. The elasto-plastic push-over is carried out to the four fiber plasterboard filled with reinforced concrete with the macro-model. The computational results are all close to those of experiments, which show that the macro model can be used to analyze the dynamic properties of composite material and has relatively high accuracy.
