To calculate the maximum positive radial moment at the center of a circular slab subjected to a uniformly distributed load, we can use the formula for the maximum moment of a simply supported circular slab. The maximum positive radial moment Mmax​ at the center of the circular slab under a uniformly distributed load W can be calculated using the formula: Mmax​=WR^2/8​ Where:

• Mmax​ = Maximum positive radial moment at the center of the slab
• W = Uniformly distributed load on the circular slab
• R = Radius of the circular slab

This formula is derived from the equations of equilibrium for a simply supported circular slab under uniform loading. It represents the maximum moment that occurs at the center of the slab. Therefore, the maximum positive radial moment at the center of a circular slab subjected to a uniformly distributed load W and fixed at its ends is given by: Mmax​=WR^2/8​
