通过12根钢筋混凝土柱(其中9根采用了高钛重矿渣集料)的偏心受压试验，研究了高钛重矿渣钢筋混凝土小偏压柱的受力性能和破坏形态。对比分析了骨料类型和偏心距对柱的极限承载力和刚度的影响。研究结果表明：相较于普通砂石，高钛重矿渣集料钢筋混凝土柱力学性能优良，承载力高于普通钢筋混凝土柱；采用了矿渣碎石、普通砂作集料的钢筋混凝土柱的刚度略大于其它集料类型。采用现行混凝土结构设计规范对高钛重矿渣集料钢筋混凝土偏压柱的正截面承载力进行计算，计算结果与试验结果相比偏于安全，且与普通钢筋混凝土试件的比较结果相同，因此可采用现行混凝土结构设计规范对高钛重矿渣钢筋混凝土偏压柱进行设计。

T he paper conducts eccentric compression test to 12 reinforced concrete columns to study the force-bearing performance and failure mode of column with high titanium heavy slag aggregate ( which accounts for 3/4 of the total specimens applied) . T he results indicate that compared with its counterpart,the specimens with high titanium heavy slag aggregate stand out in both mechanical and force-bearing performance,while columns with slag-gravel or sand as aggregate display a slightly better stiffness property. Afterwards,the paper takes reference from the current design specifications for concrete structure and carry out force-bearing calculation on the normal section of the columns with high titanium heavy slag aggregate. T he calculation results show that the conclusion arrived from the test is arguably correct,at the same time the calculation confirms the previous comparison of the specimens with high titanium heavy slag aggregate and those w ithout. T herefore,it can be said that the current specification for concrete structure can be used in the design of eccentric compression column with high titanium heavy slag aggregate.
