Abstract EN
A new method of characterizing the damage of high strength concrete structures is presented, which is based on the deformation energy double parameters damage model and incorporates both of the main forms of damage by earthquakes: first time damage beyond destruction and energy consumption.
Firstly, test data of high strength reinforced concrete (RC) columns were evaluated.
Then, the relationship between stiffness degradation, strength degradation, and ductility performance was obtained.
And an expression for damage in terms of model parameters was determined, as well as the critical input data for the restoring force model to be used in analytical damage evaluation.
Experimentally, the unloading stiffness was found to be related to the cycle number.
Then, a correction for this changing was applied to better describe the unloading phenomenon and compensate for the shortcomings of structure elastic-plastic time history analysis.
The above algorithm was embedded into an IDARC program.
Finally, a case study of high strength RC multistory frames was presented.
Under various seismic wave inputs, the structural damages were predicted.
The damage model and correction algorithm of stiffness unloading were proved to be suitable and applicable in engineering design and damage evaluation of a high strength concrete structure.
