摘要
本文对10根空心钢管柱、7根圆形核心混凝土柱、6根钢管混凝土柱进行非比例加载的双轴压扭单调受力及6根钢管混凝土柱低周及反复受力的试验研究,探索这种构件的工作反应及破坏机理。研究证明,钢管混凝土柱在压扭复合受力作用下,具有较高的强度和廷性,能充分发挥两种材料的优点,对抗震很有利。本文给出的理论简化计算公式,具有满足建筑结构统一标准安全度,可供工程设计及制定规程的参考。
In this paper 10 steel tube columns, 7 cored concrete cylinders, 6 concrete filled steel tube columns have been studied experimentally under monotonous nonproportional biaxial compressive and torsional loading, and 6 concrete filled steel tube columns under cyclic loading, the working response and failure mechanism of these elements have been preliminarily researched. The experiments demonstrated that the concrete filled steel tube columns under the action of combined compression and torsion have a high strength and a good ductility, hence the advantage of these These two kinds of materials can sufficiently be developed, especially available for aseismatic cases.
