One way Slab design Excel Sheet – Civil MDC

One Way Slab. One way slabs are such slabs in which the loads are shared only by the shorter direction of the slab. Here ratio of longer span of slab to the shorter span of slab is greater than 2. One way slab being supported on two opposite sides only leads to the structural action in single direction.【Get Price】

To design the one-way slab, a unit width (equal to 1m, 1mm) and that strip spread along the full span length. The rectangular strip has been considered the depth and the width of the strip is considered to the thickness of the slab. The load per unit length acting on this strip is calculated as the slab load per unit area multiplied by the width of the strip behaves like a wide beam and hence 【Get Price】
