摘要为研究沙漠砂混凝土框架柱的抗震性能，对15根缩尺比为1/2的框架柱开展了拟静力试验。以剪跨比、轴压比、配箍率、沙漠砂替代率和配筋率为设计参数，对构件的破坏过程、破坏特征、滞回曲线、骨架曲线、耗能能力、延性性能和刚度退化等抗震性能指标进行分析。结果表明：沙漠砂混凝土框架柱的滞回曲线较饱满，其各项抗震性能与普通混凝土柱较接近，整体上具有较好的抗震性能。沙漠砂替代率由0%、20%、40%、60%、80%逐渐增加时，沙漠砂替代率为40%的试件其各项抗震性能指标均较好，沙漠砂替代率为60%的试件，各项抗震性能指标与普通混凝土柱的较接近。剪跨比由1.32、1.70、2.08、2.64、3.02逐渐增加时，试件依次发生剪切破坏、弯剪破坏和弯曲破坏。轴压比由0.17、0.26、0.35逐渐增加时，其峰值荷载提高近20%，延性提高近5.0%，等效黏滞阻尼系数提高近10%。配箍率由0.64%、0.97%、1.29%逐渐增加时，其峰值荷载提高近5%，延性提高近30%，等效黏滞阻尼系数提高近25%。配筋率由1.55%、2.03%、2.58%逐渐增加时，其峰值荷载和延性分别提高近30%，等效黏滞阻尼系数提高近10%。

Abstract：To reveal the seismic behavior of desert sand concrete column (DSCC), quasi-static tests were carried out on 15 1/2-scale frame columns. Taking the shear span ratio, axial compression ratio, stirrup ratio, desert sand replacement ratio and reinforcement ratio as design parameters, the failure process, failure characteristics, hysteretic curves, skeleton curves dissipation capacity, ductility and stiffness degradation of DSCC were investigated. Test results showed that the hysteretic curves of DSCC specimens were plump, and the other seismic performance indexes were similar to those of ordinary concrete columns, indicating that the DSCC had the excellent seismic behaviors. When the desert sand replacement ratio ( ) increased from 0%, 20%, 40%, 60% and 80%, the specimen with the of 40% had better seismic performances, and the specimen with the of 60% had the similar seismic performances with those of ordinary concrete columns. When the shear span ratio increased from 1.32, 1.70, 2.08, 2.64 and 3.02, the specimens failed in order of shear, flexure-shear and flexure. When the axial compression ratio increased from 0.17, 0.26 and 0.35, the peak load increased by nearly 20%, ductility increased by nearly 5.0%, and equivalent viscous damping coefficient increased by nearly 10%. When the stirrup ratio increased from 0.64%, 0.97%, 1.29%, the peak load increased by nearly 5%, ductility increased by nearly 30%, and equivalent viscous damping coefficient increased by nearly 25%. When the reinforcement ratio increased from 1.55%, 2.03% and 2.58%, the peak load and ductility increased by nearly 30%, and the equivalent viscous damping coefficient increased by nearly 10%.
