中文摘要：

采用试验方法对三种高钛重矿渣混凝土类型的钢筋混凝土轴压短柱的力学性能进行了研究。从破坏形态、极限承载力、荷载-应变关系、压缩量等方面与普通钢筋混凝土轴压短柱进行对比分析。研究结果表明,同条件下三种高钛重矿渣类型的钢筋混凝土轴压短柱的破坏形态与力学性能与普通钢筋混凝土轴压短柱基本相同;三种高钛重矿渣类型的钢筋混凝土轴压短柱塑性性能和极限承载力均优于普通钢筋混凝土。采用现行混凝土结构设计规范计算了本研究所有试件的轴压极限承载力,并与试验结果进行了对比,结果表明可采用现行普通混凝土结构设计规范对高钛重矿渣钢筋混凝土柱的轴压极限承载力进行计算。最后,采用有限元法对所有试件的荷载-变形过程进行了计算,有限元计算曲线与试验结果吻合良好。

英文摘要：

The mechanical behaviors of steel reinforced concrete columns with three types of high titanium heavy slag aggregates were studied by experimental method.The failure mode, load carrying capacity,load - strain relationship and compressive ratio for each speci- men were analyzed and compared with each other. The test results indicate that the axial compressive behaviors of steel reinforced concrete columns with high titanium heavy slag aggregate are similar to those of steel reinforced conventional concrete columns.The ine- lastic performance and load carrying capacity of the columns with high titanium heavy slag aggregate are little superior to those of con- ventional concrete column.The load carrying capacity of the columns with high titanium heavy slag was calculated based on the current specifications and compared with the conventional concrete column.The results indicate that the current design standard is applicable for the calculation of the axial compressive strength of the steel reinforced concrete columns with high titanium heavy slag aggregate.Final- ly, the load - deformation relationship was analyzed by finite element method for specimens, which indicates that the simulation results agree well with the experimental results.
