Options with radial and longitudinal-transverse rib arrangement were considered. The research was carried out by numerical simulation in the ANSYS program. The values of stresses and deformations in the tank bottom were obtained depending on the number and location of stiffeners on it. It is established that the main load is perceived by the Central part of the ribs. Therefore, due to the correct selection of stiffeners, it is possible to reduce the thickness of the head plate. To equalize the stresses on the head surface, the number of edges should be at least six, and the radial placement of the edges is more preferable. With the same deformations, in this case, the stresses in the head are somewhat less. The results obtained make it possible to increase the strength of the flat head and use it in tanks intended for storing liquid and gaseous substances under low pressure.
