Total moment of the forces on the section of the beam around the neutral axis, also termed as moment of resistance, could be secured by integrating the above equation and we will have. The moment of resistance is calculated by taking the moments of forces about the centre of gravity of the tensile steel. The sum of forces acting on a particle of constant mass is equal to the product of the mass of the particle and its acceleration. Moment of inertia of a group of piles about x x axis through cg of group. The moment of resistance of the concrete section is the moment of couple formed by the total tensile force t in the steel acting at the centre of gravity of reinforcement and the total compressive force c in the concrete acting at the centre of gravity c. Since shear and moment usually develop simultaneously with torsion, a reasonable. When the sum of the forces acting on a particle is zero, its velocity is constant. Ultimate torsional strength of solid and hollow sections of. Mat or raft foundation is a large concrete slab supporting several columns in two or more rows. It is used where the supporting soil has low bearing capacity.
