The Use of Nonlinear Static and Dynamic Methods in High-Rise Buildings under Rare Earthquake

Abstract eng:
This paper discussed the use of nonlinear static and dynamic methods in high-rise buildings under rare earthquake in China these years. These nonlinear static and dynamic analysis methods were based on the independency software PUSH&EPDA of PKPM serial structure design software. This paper gave out the main methods and processes of nonlinear static and dynamic analysis, such as the steel and concrete stressstrain model in structure components, finite element models of beam, column, brace and concrete shear wall, the processes of nonlinear static and dynamic methods in EPDA software. Some analysis examples of test model and high-rise building using the nonlinear static and dynamic methods are gave out. This paper discussed how to use the nonlinear static and dynamic methods in engineering applications, what can the numerical simulation tell us under rare earthquake and how to improve the design of buildings based on the nonlinear static and dynamic analysis.
