【摘要】 攀钢高炉渣为当地新型建筑材料,属低钙富钛重矿渣,具有多孔、强度高等特征。通过对12根高炉半矿渣混凝土常规框架模型柱的低周反复荷载试验,从轴压比、箍筋形式、强度等方面分析了各柱的滞回曲线、骨架曲线、位移延性等指标的变化趋势;结合《抗规》和《混规》等规范的相关条文,重点对半矿渣混凝土与钢筋的粘结性质、柱的延性性能进行分析。更多还原

【Abstract】 With low content in CaO and high content in TiO2,Panggang slag aggregate is a special local building material with characteristic of multi-hole and high strength.Subjected to horizontal low cyclic loading,based on experiment of 12 columns composed by fine aggregate of slag materials,change trend of indexes,such as hysteretic curve,skeleton curve and displacement ductility,induced by variation of axial compression ratio,shapes of hoop and concrete strength etc,are analyzed.Combined with related rules of codes for seismic design of buildings and design of concrete structures etc,bond behavior between fine slag aggregate concrete and reinforcement and practical column’s ductility performance are analyzed particularly.更多还原
