Buckling of Cylindrical, Thin Wall, Trailer Truck Tanks and ASME Section XII

New hazmat (hazardous material) transport tanks will be constructed to the rules of the ASME Code Section XII. The criteria and basis to design these tanks have been questioned and a full scale buckling test has been performed to evaluate maximum allowable over-the-road loadings and required design details. This paper summarizes the results of this testing and provides comparisons with classical Code buckling criteria, Code Case 2286 and other methods for such evaluations. The objective is to provide the ASME Section XII committee with a basis for establishing buckling design criteria and shell stiffening details for both hazmat and nonhazmat transport tanks.
