Ribbed slabs are slabs cast integrally with a series of closely spaced joists which in turn are supported by a set of beams. The main advantage of ribbed floors is the reduction in weight achieved by removing part of concrete below the neutral axis. … Solid slabs of uniform thickness can be one-way or two way.
