Influence of Restraining Stiffness on Mechanical Properties of Suspen-Dome

Abstract:

Suspen-dome is a kind of large-span prestressed hybrid structure, To understand the influence of radial restraining stiffness to structural mechanical response, and to ensure radial restraining stiffness reliable during designing, a rib 3 type suspen-dome and corresponding single layer lattice shell were selected, their static response under different radial restraining stiffness were studied and compared .At the same time, basic dynamic properties of a rib 3 type suspen-dome were analyzed under different radial restraining stiffness. The results show that the sensitivity of single layer dome mechanical response to radial restraining stiffness will be reduced because of the bottom cable-struts, enhance of radial restraining stiffness will not influence structural mechanical response after radial restraining stiffness reaches certain value.
