Abstract: Great variation of vertical stiffness and bearing capacity of the complex tall buildings,which have characteristics of complexity of stress and are easy to form weak site. Elastic-plastic analysis method should be adopted to calculate the complex tall buildings. Based on existing elastic-plastic analysis method, the paper was emphasis on the objective, principle, method of elastic-plastic analysis and pointed out the problems for attention on elastic-plastic analysis method. Finally, elastic-plastic analysis method in the engineering application was provided.
Keywords: complex tall building; elastic-plastic time-history analysis; seismic behavior
