Design of RC slabs to satisfy both bending and deflection criteria

摘要

The design approach for RC slabs given in the Indian standard code for design of plain and reinforced concrete structure, (IS 456 : 2000) has been reviewed and a method for direct design of singly reinforced rectangular concrete slabs, to simultaneously satisfy the condition of bending and the serviceability is presented. Design charts are provided allowing practical application of this method to enable the design engineer to adjust the steel reinforcement and depth. Design charts are also provided to find out effective depth when the area of steel to resist the bending is just adequate for deflection criteria. Examples are shown to explain the use of these charts.
