摘要
进行了7根型钢再生混凝土柱的拟静力试验,试件的主要设计参数为再生骨料取代率、轴压比和体积配箍率.试验结果表明:再生骨料的掺入未使试件的水平承载力、延性和耗能能力明显降低,对型钢再生混凝土柱的抗震性能影响不大.轴压比过大,型钢再生混凝土柱的抗震性能有较大幅度的降低.增大体积配箍率,型钢再生混凝土柱的延性和耗能能力有所提高,水平承载力也略有增大.本文的研究可为型钢再生混凝土柱在实际工程中的应用提供参考.
The pseudo-static tests were carried out on seven steel reinforced recycled concrete columns. The main design parame- ters of specimens were the recycled aggregate replacement ratio, axial compression ratio, and volumetric stirrup ratio. The results indicate that the incorporation of recycled aggregate doesn＇t reduce the horizontal bearing capacity, ductility and energy dissipation capacity of the specimens and has little effect on seismic performance. The seismic performance of steel reinforced recycled con- crete column decreases significantly in high axial compression ratio. The ductility, horizontal bearing and energy dissipation capac- ity of steel reinforced recycled concrete column increases simultaneausly with the volumetric stirrup ratio. This study provides a reference for the application of steel reinforced recycled concrete column.
