Comparative Analysis of Elasto-Plastic Time History of a Ultra-High-Rise Frame Tube Structure
The seismic performance analysis of reinforced concrete structures under earthquake action is compared between SAUSG and YJK-EP finite element analysis software in terms of modeling,analysis,and calculation results.To ensure consistency in analysis,the main parameters of the two software are set to be the same,and the same seismic wave input is used for different software.Through comparative analysis,it is found that two software have high consistency in calculating structural natural vibration characteristics,top displacement,inter story displacement angle,story shear force,base shear force,and damage status,proving the effectiveness of the two software in analyzing and evaluating the seismic performance of rein-forced concrete structures.Due to the selection of different calculation methods and damping models for two software during analysis,some calculation results may differ in specific conditions.Therefore,when u-sing these two software for seismic performance analysis,factors such as the frequency characteristics,am-plitude,and interaction with the structural of seismic waves should be fully considered to obtain more accu-rate and reliable results.The problem of uneven stiffness in structures on specific floors has been pointed out,providing a reference for further optimization of structural design and improvement of structural per-formance.
