Analysis Of Nonlinear Static And Dynamic Response Of Frame-supported Ribbed Panel Structures

The frame-supported multi-ribbed structure is a new type of seismic structure with light weight and energy saving performance.The finite element simulation analysis of the framesupported ribbed panel structure is established base on experimental model,and nonlinear time-history analysis of frame-supported ribbed structure.The main research contents are as follows:(1)For the four test models,finite element simulation analysis was carried out with ABAQUS finite element analysis software,and compared with the test results.The calculated results were similar to the test results,laying a foundation for further finite element analysis.(2)On the basis of experiment and finite element simulation analysis,the damage performance of Frame-Supported Multi-Ribbed panel structure is analyzed.Based on twoparam eter damage model of deformation and hysteretic energy dissipation,energy dissipation factor is studied,and the damage model of Frame-Supported Multi-Ribbed panel structure is proposed,which provides a theoretical basis for the damage analysis of Frame-Supported Multi-Ribbed panel structure.(3)Finite element simulation software ABAQUS was used to conduct modal and nonlinear time-history analysis of frame-supported ribbed structure.The structural period,mode,frequency,maximum vertex displacement,maximum interlaminar displacement angle and maximum acceleration of this structures were studied.
