Effective Initial Stiffness and Deformation of Recycled Aggregate Concrete Columns Under Seismic Loads

Abstract eng:
This paper deals with the effective initial stiffness and lateral deformation capacity of recycled aggregate concrete (RAC) columns under seismic loads based on existing experimental database. The characteristic of these existing studies and main research results regarding the seismic behavior of RAC columns were reviewed shortly. Based on this database, the effects of main structural factors on effective initial stiffness (EIS) and maximum drift ratio (MDR) which corresponding to maximum lateral resisting force of RAC columns were analyzed, respectively. According to the comparative results reported in this study, effective initial stiffness and maximum drift capacity of RAC columns were discussed and modeled simply considering the effects of several structural factors on seismic performance of RAC columns. To evaluation the accuracy and reasonability of the two proposed models, existing evaluation models for predicting EIS and MDR of reinforced concrete (RC) columns were collected and compared with the proposed two models using the database. Comparative results implied that the two proposed models both evaluate the experimental results with a good agreement.
