［摘要］钢骨混凝土柱具有良好的抗震性能，但其在高层建筑结构中施工复杂，为此，基于核心区钢骨含钢量相同的原则提出了新型分散式钢棒混凝土柱。为研究分散式钢棒混凝土柱的抗震性能，对2组各3个不同核心材料钢骨混凝土柱在指定试验轴压比下进行了水平低周反复荷载试验。通过试验得到的荷载-位移曲线，对比分析了不同核心材料的钢骨混凝土柱耗能和骨架曲线的差异。初步试验结果表明分散式钢棒核心钢骨混凝土柱的抗震性能良好。

［关键词］分散式钢棒混凝土柱；低周反复荷载；抗震性能；滞回曲线

Abstract: Steel reinforced concrete (SRC) columns have good seismic performance, which are difficult to construct on high-rise buildings. Based on the same steel contain rate of the core area, a new type SRC columns with distributed steel bars was proposed. In order to study the seismic performance of this new type of columns, experiments on two groups (each group has three specimens) SRC columns with different material in the core area on specific axial compression ratio under low cyclic loads were carried out. Based on experimental study, the loading-displacement hysteretic curves were measured, and the behavior of energy dissipation and skeleton curves of six specimens were analyzed. It was observed from the results that SRC columns with distributed steel bars have good seismic performance.

Keywords: steel reinforced concrete column with distributed steel bar; low cyclic load; seismic performance; hysteretic curve
