【Abstract】 The structural performance of recycled aggregate concrete( RAC) was mainly investigated and analyzed,and the latest research progress on the structural performance of RAC was reviewed in detail. The flexural and shear performances of RAC beam,flexural bearing capacity of RAC slab,bearing capacity of RAC column,seismic performances of RAC shear wall and RAC masonry wall,basic mechanical property and seismic performance of RAC beam-column joint were analyzed.The bearing capacity,deformability and seismic performance of RAC planar frame under the horizontal low cyclic loading were analyzed. Furthermore,the dynamic properties,the seismic responses,the structural ductility and the seismic damage assessment of RAC spatial frame and block masonry structures under the dynamic loadings were investigated and discussed.The studies on the structural performance of RAC from home and abroad show that RAC structure( member) with proper design and construction can basically meet the structural performance of normal aggregate concrete structure( member) and be used in civil engineering. It is feasible to apply and popularize RAC building in seismic fortification areas.更多还原
