建立了凹陷钢管构件的分析模型。利用该模型，推导了轴力和双向弯矩之间的极限强度相关关系。介绍了在用理想结构单元法（ISUM）分析钢管空间刚架非线性性能时，考虑凹陷和弯曲损伤时，这种相互作用关系的实现方法。本文报道了纯弯曲凹口构件的试验研究。与理论预测的比较。
An analytical model of dented tubular members is constructed. Using this model, an ultimate strength interaction relationship between axial force and biaxial bending moments is derived. The implementation of this interaction relationship to take account of denting and bending damage in the analysis of nonlinear behavior of tubular space frames by ISUM (the Idealized Structural Unit Method) is described. An experimental study of the behavior of dented members subjected to pure bending is reported. Comparison with theoretical predictions is presented.
