For a slab supported on its four edges with corners held down and loaded uniformly, the Marcus correction factor to the moments obtained by Grashoff Rankine’s theory

A. Compressive and tensile B. Tensile and compressive C. Both compressive D. Both tensile

A. At a distance of effective depth of slab from periphery of column/drop panel B. At a distance of $$\frac{{\text{d}}}{2}$$ from periphery of column/capital/drop panel C. At the drop panel of slab D. At the periphery of column

A. depends on as, only B. depends on aCbC only C. depends on both crst and acbc D. is independant of both ast and acbc where d is the effective depth, ast is per-missible stress in steel in tension and ocbc is permissible stress in concrete in bending compression.

A. More than or equal to one fourth of diameter of main bar B. More than or equal to 5 mm C. More than 5 mm but less than one-fourth of diameter of main bar D. More than 5 mm and also more than one-fourth of diameter of main bar
