Nonlinear Analysis and Construction Method of a Silo Dome with Grain

Abstract:

Combined with the project which a grain silo need be transformed, a new type of silo is put forward. The silo system consists of supporting columns, the silo body and latticed shell roof structure. In view of the force is different between silo shell roof and conventional roof, and silo shell roof prones to buckling failure. The linear and nonlinear buckling analysis was carried out for latticed shell with a diameter of 20m, the results show that the buckling loads obtained by linear buckling analysis is greater than that obtained by nonlinear buckling analysis, and nonlinear analysis is more secure for structures. Through the comparison the rationality and stability of reticulated shell design are verified, finally construction measures of this system are given, and these can provide references for design and construction of similar engineering.
