RELIABILITY ANALYSIS ON BEARING CAPACITY OF FRAME STRUCTURES WITH RECYCLED AGGREGATE CONCRETE

摘要

The reliability of bearing capacity for recycled aggregate concrete(RAC)frame structure is theoretically analyzed in this paper.This investigation concludes that the failure pattern and failure mode of RAC frame structure is almost the same as that of natural aggregate concrete(NAC)frame structure.However,due to the increase of compressive strength discreteness of RAC,which results in the increase of resistance discreteness of RAC columns and beams,the bearing capacity reliability of RAC frame structures decreases.The results show that the reliability index of RAC frame is slightly lower than that of NAC frame and it is feasible to apply RAC in practical engineering.
