Effective depth, d= Distance between the centroid of the area of tension reinforcement and the maximum compression fiber.

Deflection:

• The final deflection due to all loads including the effects of temperature, creep and shrinkage should not exceed .
• The deflection including the effects of temperature, creep and shrinkage occurring after erection of partitions and the application of finishes should not exceed .
