The use of a central circular core to resist wind loads offers certain advantages in the construction of high rise buildings. Annular slabs, fixed at the inner boundary, supported by equally spaced columns on the outer boundary, and subjected to uniformly distributed transverse load are examined. The problem is solved under the assumption that the columns do not restrain the rotation of the slab, and that the column reactions are uniformly distributed over its width along the boundary. The influence of the column number, the column width, and the core radius, is studied with the deflection and stress resultants plotted for several informative cases.
