An efficient numerical method of analysis for environmental (thermal, shrinkage, and swelling) effects in circular, concrete, liquid storage thin-walled tanks under conditions of axial symmetry is outlined. Although the approach is based on individual analyses of wall and plate sub-structures, it yields the global solution that accounts for actual interaction between the wall and plate elements. This interaction between the tank main elements is introduced in a Force method-type procedure by utilising conditions of compatibility of displacements at the Wall-plate junctions.
