Mechanical, mechatronic and adaptive technologies for the stabilization of beam-columns and truss structures (C02)

桁架结构中轴压梁柱屈曲引起的突然失效的不确定性可通过主动稳定或主动屈曲控制来控制。通过压弹性支承实现了单梁柱的主动屈曲控制。具有时变轴向荷载的多个梁柱的网络控制影响着大型桁架结构的整体动力行为，如SFB-Demonator。单个桁架组件的故障以及随着时间的推移在几何或动力学方面的不可预见的变化都可以通过主动技术进行补偿。

Uncertainty of sudden failure due to buckling of axially loaded beam-columns in truss structures is con-trolled by active stabilization or active buckling control. Active buckling control of single beam-columns is achieved by piezo-elastic supports. Network control of multiple beam-columns with time-varying axial loads influences the global dynamic behavior of larger truss structures such as the SFB-demonstrator. Failures of individual truss components as well as unforeseen changes in geometry or dynamics over time are compensated by the active technology.
