摘　　要：本文通过对压杆横向支撑的刚度、内力的分析,揭示了横向支撑能否有效地减小压杆计算长度取决于支撑的刚度。在横向支撑满足一定刚度的条件下,压杆屈曲时支撑有刚度储备才能保证压杆临界荷载的增加。Through the analysis of the stiffness and internal force of the horizontal support of the pressure bar,it is revealed whether it is effective to reduce the length of the pressure bar by lateral bracing depends on the stiffness of the support.Under the lateral bracing satisfies a certain stiffness,It can be used to support the increase of the critical load of the pressure bar.

关 键 词：支撑 刚度 内力 稳定
