Abstract

Spherical composite ribbed shell is made of thin reinforced concrete shell and composite ribs, which has many advantages such as large span, high rigidity, and large bearing capacity and low cost. It is one of the urgent issues to considering the mechanical performance under dynamic loading. Based on nonlinear finite element theory, a numerical calculation model is built, and then the dynamic response of composite ribbed shell under step load and seismic wave are respectively discussed. The results shows: under the vertical step load, a positive symmetric deformation appeared in unstable status; under horizontal step loads, an anti symmetric deformation emerged. While as the seismic wave was exerting, structural damage caused by thin concrete shell damage and plastic deformation development, namely it was the synthetic action result of structural stiffness weaken and P- effect from geometric nonlinear, so structure damage was the comprehensive effect of strength failure and dynamic instable.
