A new structure linking large-scale spherical tank brace and spherical shell

The paper presents a new structure, i.e. radial pallet, to link spherical tank brace with spherical shell. With themethod indicated in JB4732 Steel Pressure Vessels Analysis and Design Standards, this new structure is analyzed for itsstress with ANSYS, a finite element software, and also correlated with the horizontal pallet. Results show that under theconditions of self-weight+calculating pressure+wind pressure, local stress at shell-pallet connection decreases by 9%, underthe conditions of self-weight+calculating pressure+25% wind pressure+earthquake load, local stress at shell-plate connectiondecreases by 9%, under conditions of self-weight+test pressure, local stress at shell-pallet connection decreases by 10%.
