Abstract

The understandings of seismic mechanisms of tensegrity are highly demanded for perfecting the design principle. Due to the characteristics of periodicity, the effect of pre-stress on the frequencies of unit cell is investigated. And the stiffness of the basic tensegrity units was derived analytically. Then the vibration analysis of the entire assembly tensegrity structure is conducted numerically. Through parametric study, the influence of the pre-stress level on strength capacity of tensegrity is investigated. The cables yielding and bars buckle are considered. The influential factors on stiffness were evaluated, which can provide a guidance to the seismic mitigation optimization.
