并用附加弯矩的概念论述了区分压杆的强度和稳定问题的标志，说明压杆的第二类稳定问题和梁柱问题具有共性——均属于强度问题。
The criterion judging strength and stability problems may be obtained by using the concept of additional moment, and the general character of these structures is that they belong to strength problem.
计算了结构与运动刚体之间的冲击力时程曲线、梁中的剪力及弯矩分布、轴力杆件中的轴力分布。
The impact force-time history between the structure and the moving rigid-body, shear force and bending moment distribution along the beams, axial force distribution along the bars were calculated.
指出传力杆模型对模态频率和主振型有直接影响，动力分析中应当考虑接缝的剪力传递和弯矩传递。
The transfer of shearing and moment must be considered in dynamic analysis because the model of dowel bar affects the modal frequency and modal shape directly.
