A cantilever beam of size 230 × 400 mm (effective) has a clear span of 25 m and is supported on a 400 × 400 mm column. The effective span of the cantilever is-
25.2 m
Method Effective Span Calculation Result (m) Clear span + d/2 25 \, m + 400 \, mm / 2 25.2 m Clear span + Support width / 2 25 \, m + 400 \, mm / 2 25.2 m Since both calculations yield the same result, 25.2 m, the effective span of the cantilever beam is 25.2 m.
If W is the load in a circular slab of radius R, the maximum radial moment at the center of the slab is
If the ratio of the span to the overall depth does not exceed 7, the stiffness of the beam will ordinarily be satisfactory in case of a
The maximum permissible size of aggregates to be used in casting the ribs of a slab is
The thickness of the topping of a ribbed slab, varies between
In order to satisfy the requirements of Fe500D steel for reinforcement purpose, the 0.2% proof stress (MPa) should be a minimum of:
