Mathematical structural analysis of one way ribbed slabs was introduced in this paper. The results of this analysis are compared with the results of the finite element method by SAP program. In SAP program, the model has been divided to frame elements "to represent ribs and beams" and shell elements "to represent the slab and solid part Minimum Depth. Minimum depth of the one-way concrete slab, most of the times is governed by deflection criteria. Sometimes the minimum depth is adequate as per flexure design, but if deflection criteria aren’t fulfilled such slabs will face vibration even under small loads like walking, jumping, etc.
