STUDY ON THE MECHANICAL BEHAVIOR OF GFRP PLATE-CONE CYLINDRICAL RETICULATED SHELL

Plate-cone reticulated shell is a new type of spatial structures through innovation and development by authors. In this paper, GFRP composite is applied to the cones of plate-cone reticulated shell. Through model test for the first time, the ultimate bearing capacity, load transmission way and the whole destroy process of GFRP plate-cone cylindrical reticulated shell are studied deeply. Through comparing with the results of the ANSYS simulation, the correctness of the theoretical analysis and structure reliability are verified, the stress mechanism and damage characteristics of composite plate-cone reticulated shell are revealed and summarized. Theoretical basis and suggestions in the design for GFRP plate-cone reticulated shell are provided in the paper for application of this type of structure in the field of practical construction.
