Analysis for Composite Material in Plate-Cone Reticulated Shell
Abstract:
Plate-cone reticulated shell is a new type of space structures with good mechanical behavior and technical economy. Composite material plate is light and strength is high, its ratio intensity is higher a lot than steel material, and elasticity property can be designed, so composite material plate specially applies to prefabricated cone unit of plate-cone reticulated shell. In this paper, GRP plate is regarded as linear elastic material from a view to the engineering application, the multi-layer plate element stiffness matrix is derived with the classic theory of plate and shell, and the GRP plate is designed with equivalent method. Furthermore, the static characteristics for plate-cone reticulated shell with composite material plates are also analyzed in the paper. It is proved by the study that plate-cone reticulated shell with composite material plates is more advantageous and has wide application foreground.
