锥形中空夹层管混凝土(CFDST)柱常被用于输电塔并有可能成为另一种类型的复合框架结构。然而,尚未对偏心受压下锥形中空夹层钢管混凝土柱的性能进行研究,对不同偏心荷载作用下的锥形中空夹层混凝土柱进行研究。数值研究也使用了有限元模型对锥形构件的性能进行了预测。比较锥形构件和直角构件的强度和应力分布。通过数值计算研究锥形柱的稳定性。最后,使用“等效柱”的概念预测偏心受压下锥形中空夹层钢管混凝土柱的荷载力。
Conical hollow sandwich concrete (CFDST) columns are often used in transmission towers and are likely to be another type of composite frame structure. However, the performance of conical hollow-sectioned CFST columns under eccentric compression has not been studied, and the cone-shaped hollow interlayer concrete columns under different eccentric loads have not been studied. Numerical studies also used finite element models to predict the performance of tapered members. Compare the strength and stress distribution of tapered members and right-angle members. The stability of tapered columns is studied numerically. Finally, the concept of “equivalent cylinder” is used to predict the load capacity of conical hollow-walled CFST columns under eccentric compression.
