This study presents a variable-stiffness vibration suppression technique for slender truss structures actuated by axial tension cables, with which the constraints imposed by the height of vertical masts are circumvented. It incorporates modal truncation to enhance vibration suppression efficacy while refining the stiffness selection strategy. Furthermore, this paper explores the dynamics of pseudo-active and passive effects and optimizes the cable installation positions to enhance the passive effects. The validity of all these concepts proposed above is substantiated through comprehensive numerical simulations. Similarly, a targeted design of a 6-m-long truss structure was developed, and the feasibility of the variable-stiffness vibration suppression technology proposed in this paper was validated through physical experiments.
