Buckling of Aboveground Storage Tanks with Conical Roof
نویسنده
چکیده
The buckling of aboveground circular steel tanks with conical roof is considered in this paper. The specific source of loads investigated is wind action during hurricane storms in the Caribbean islands. The structure is modeled using a finite element discretization with the computer package ALGOR. Bifurcation buckling of the shell is computed for a given static wind pressure distribution. Then the bifurcation loads and buckling modes are compared with the evidence of real tanks that failed during hurricane Georges in Puerto Rico in 1998. Several pressure distributions are assumed for the roof of the tank, and it is shown that the results are highly sensitive to the choice of pressures.
