对一种新型的薄壁波纹钢管混凝土柱进行了低周反复荷载作用下滞回性能试验研究，然后利用ABAQUS进行模拟分析，分析了钢板截面宽厚比、长细比、钢板强度、混凝土强度等4个因素对薄壁波纹钢管混凝土柱局部屈曲的影响规律。试验结果表明：薄壁波纹钢管混凝土柱宽厚比、长细比基本与屈曲荷载成反比，钢板强度与屈曲荷载成正比，混凝土强度基本与屈曲荷载无关。

This paper presents an experimental research of hysteretic performance on a new kind of thin wall corrugated steel pipe concrete column under the effects of low cyclic load. The simulation analysis is carried on by ABAQUS towards the influence of such four factors as steel cross-section width-thickness ratio, slenderness ratio, steel strength, concrete strength on the thin wall corrugated steel pipe concrete column local buckling. The main conclusions are as follows: there is an inverse correlation between its width to thickness ratio, slenderness ratio and local buckling load; steel strength is proportional to the load; concrete strength has no effect on the load.
