Through theoretical analysis and numerical calculation, comparison and analysis is carried out of the models often used with the frame structure on construction emulation analysis. The characteristics and problems of the models were pointed out.Based on the work of previous researchers,this paper also points out a new model. According to the model the whole structure is divided into base structure and recurrence structures and used substructural matrix-displacement method to analysis. The effects of base structure or former substructures on later substructures were emulated by elastic restrains. Numerical example shows that the model was not only practical,but also easy to deal with in numeric preparatory.
