The Damage Evolution of Concrete Structure under Earthquake


Article Preview

Theoretical study on earthquake damage under seismic load about of concreate structure,in order to better study the damage evolution mechanism of reinforced concrete frame structure in earthquake. The two-parameter seismic damage factor model,which is based on deformation and dissipation,was improved using the theoretical analysis method in this study .Using the three-level earthquake-resistant design damaging index based on the importance of structure as the collapse criteria for evaluation. Using the nonlinear dynamic finite element method and do a collapse numerical simulation analysis of a three layers concrete frame. Calculate the dynamic response and damaging factor of each time step, and study the damage evolution.The results show that the improved damage index calculating model can calculate both on the maximum damage index and structure damage index quantificationally and continuously and describe the process of collapse damage of the integral structure.
