Fiber Element Based Elastic-Plastic Analysis Procedure and Engineering Application

摘要

Elastic-plastic time history analysis of super high-rise building is accomplished by the program PERFORM-3D to evaluate the global response and component deformation of structure based on fiber element theory. Direct modeling of a tall building in PERFORM-3D is complicated; hence a pre-process program ETP is established for a more effective and accurate modeling. Analysis improves that fiber element-based nonlinear analysis of the overall structure reveals the macro properties of the structure as well as the force-deformation relationship for the component and stress-strain relationship for the fiber in the micro scope. Finally, the global response, component deformation and energy dissipation of the complicated tall building designed by the current codes subjected to severe ground motions are studied in one engineering practices.
