The paper analyzes the effect of the location of horizontal ties on the deformability of the bottom of the floating pool. The bottom of the pool is a spatial structure, which is made up of trusses connected between the goiter with the help of spacers and ties (elms). The shape and dimensions of the cross-sections for the racks, braces and girders of the trusses have been determined. Two schemes for placement of horizontal ties are proposed. Using the finite element method based on a computer simulation experiment, the influence of the location of horizontal ties on the deformability of the pool bottom was investigated. Numerical values of deflections were calculated for different schemes of arrangement of elms. The optimal layout of connections, which ensures minimal deflections of the bottom, has been identified. The nature and features of the deformation of the bottom of the pool with two schemes for the location of the elms were determined.
