In order to avoid large deformation even overturning during normal service condition, it is necessary to analyze the overall stability and propose reasonable foundation form.By using large-scale finite lement software, this paper analyzes and pares the influence of different layouts of the diagonal brace on the deformation of lattice tower crane foundation deformation. The results prove the effect of arrangement form of diagonal brace on the bearing capacity of steel structure, and the design of the arrangement form of diagonal brace should be optimized before construction.
