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, the experimental study on the unsymmetrical loading of biaxial compression-twist force for 10 hollow steel tubular columns, 7 circular core concrete columns and 6 CFST columns and the low-cycle and repeated stress tests of 6 CFST columns are studied. Work response and failure mechanism of this component. Studies have shown that concrete-filled steel tubular columns have high strength and stiffness under the compression and torsion composite stress, and can fully exert the advantages of both materials, and are very beneficial to earthquake resistance. The theoretically simplified calculation formula given in this paper has a unified safety standard for building structures and can be used as a reference for engineering design and development procedures.
