Tall Building Structure’s Heightening Reform and Elasto-Plastic Analysis
Aim at one tall building structure model, which is a nonlinear three-dimensional finite element model. ANSYS FEM software is used to set up the structure model, proceeding modal analysis on natural vibration period and vibration model; ANSYS FEM software is used to import El Centro and Taft acceleration time-travel curves, which are used in 7 degree film, proceeding elasto-plastic analysis, and compared with the result of PKPM software earthquake static effect, the layer displacement calculation results contrast between two software shows it is consistent, but contrary results occurs in ISDA. So for the similar project design auxiliary FEM analysis is needed; Seven degree rarely met earthquake acceleration time-travel data and larger seismic peak acceleration time-travel imported to research the plastic development.
