摘要:

The shaking table test on a 1/4 scaled 8-story reinforced semi-recycled concrete (RSRC) frame was conducted to study the failure mode and seismic performance of the frame. The earthquake scenarios of the shaking table test included four levels, i.e. frequently occurred, basic level, and rarely occurred earthquakes of intensity 8, and more strong earthquake larger than rarely occurred earthquakes of intensity 8. Meanwhile, elasto-plastic time history analysis and fragility analysis were carried out to simulate and evaluate the behaviors of the RSRC frame. The results indicate that the failure mechanism of the structure is strong column and weak beam. The structure can meet the requirements in code for seismic design of buildings during the frequently-occurred earthquake as well as the rarely-occurred earthquake. The structure can meet the inter-storey drift ratio limit in code for seismic design of buildings. The probability exceeding the state of Immediately occupation (inter-storey drift ratio is 1/550) is 79.30%, but the probability exceeding the state of life safety (inter-storey drift ratio is 1/50) is 32.29%, which can meet the requirements in the seismic design code in the sense of probability.
