Design of Flat Plate Slab [pdf]

Structural Concrete Slabs are constructed to provide flat surfaces, usually horizontal, in building floors, roofs, bridges, and other types of structures. The slab may be supported by walls, by reinforced concrete beams usually cast monolithically with the slab, by structural steel beams, by columns, or by the ground. The depth of a slab is usually very small compared to its span.

The design I am going to share with you today is Design of Flat Plate Slab as by definition;

Flat plate slab is that in which slab is directly supported on columns without column capital, drop panel or beams. 

This design is a complete flat plate slab design, from shear to bending along with design of columns and shear head reinforcement.

Features of the design

This flat plate slab design is hand written involving each step by step detailed calculation with drawings and detailing. 

Steps involved in Design of Flat Plate Slab

• Load Calculation
• Total Factored Static Moment
• Limitations of DDM
• Longitudinal Distribution of Moments
• Torsional Constant C
• Transverse Distribution of Longitudinal Moments
• Design of Slab Thickness and Reinforcement
• Shear Design
• Design of Columns
• Design of Shear Head Reinforcement
