| 摘 要： | 探讨了钢结构构件在竖向动力荷载下的动力稳定性问题，分析了自重、杆的尺寸效应对杆动力稳定性和动力稳定临界荷载的影响，分析表明，杆的尺寸效应和杆长及阻尼力对结构动力稳定临界荷载影响较大，而杆自重影响较小，并提出了在实际工程中减小振动的一些措施，可为结构动力设计与分析提供参考依据.

| Abstract: | The problems of dynamic stability of steel structural members under vertical dynamic loads are discussed. The influence of deadweight and damping force as well as the sizeeffects of bars on dynamic stability and the related critical load are studied. Results show that the sectional sizes, the length of bars and the damping force are of bigger influence on the critical load of dynamic stability. However, the effect of dead weight of bars is relatively smaller. Some measures for vibration reduction of members in practical engineering are proposed and it is hopeful about that these measures would be of some reference value on dynamic design and analysis of structure. |
