Abstract

Three‐dimensional recycled aggregate concrete (RAC) nonlinear finite element models are developed by OpenSees software to investigate the seismic responses of a 1/4‐scaled six‐story, two‐bay and two‐span RAC space frame, which has been tested on a shaking table subjected to various earthquake scenarios. The simulated natural frequencies and vibration modal shapes, the acceleration amplification factors, the maximum story displacements and the inter‐story drifts are carefully validated by and compared with the test data with overall good agreement.
