摘　　要：为了推进攀钢高钛重渣规模化应用,保护长江上游生态环境,以轴压比、混凝土强度等级、配箍方式、配箍率和主筋配筋率作为主要参数,以高钛重渣砂作为混凝土的细骨料,制作了11根高钛重渣砂高强混凝土缩比模型柱,对高钛重渣砂高强混凝土进行了拟静力试验,并对其滞回曲线、骨架曲线、强度退化、刚度退化、耗能能力、层间位移角和延性作了详细分析。研究表明,高钛重渣砂高强混凝土柱的抗震性能与普通骨料高强混凝土柱基本相当,可以用普通骨料高强混凝土柱的抗震设计方法和构造措施进行高钛渣砂高强混凝土柱的设计和施工。For expediting the large - scale application of high titanium heavy slag and protecting the ecological environment of Yangtze River＇ s upper reach, taking axial load ratio, concrete strength, transverse reinforcement configu.ration, volumetric ratio of transverse reintorcement, longitudinal steel ratio into consideration as primary parameters, eleven model columns of high strength concrete with high titanium heavy slag （ HSC - HTHS） as fine aggregates were experimentally studied. The quasi - static test of eleven HSC - HTHS model columns were carried out. Lateral force displacement hysteretic curve, strength and stiffness degradation, energy absorption capacity, ultimate story drift angle and displacement ductility factor of model columns were studied. It is found from the test result that HSC - HTHS model columns provide comparable seismic performance to those usually used in reinforced concrete column. The design and construction of HSC - HTHS column can use the methods for usual reinforced concrete column.
