The paper introduces nonlinear analysis models and methods and their application in simulating the earthquake response and damage of building structures.For nonlinear analysis of huge building structures based on the force displacement relation of individual structural members,simplified but reliable analysis models are required.Therefore,the multi spring model,fiber model and one component spring model are now further developed and used in the structural nonlinear analysis.The multi spring model and fiber model can represent the interactions among axial load and bi directional bending moments hence are used for modeling the column and shear wall in building structures for three dimensional analysis.Using these models the authors developed a computer program and applied it in the response analysis of an earthquake damaged RC apartment building.The analysis results explain well the building responses and damage.
