Assessment of Deflection for Deck Slab Bridge
Abstract: The deflection of deck slab is found with respect to bending stress and normal stress and compared with its permissible value. Span of the deck slab plays an important role in deflection. As span increases more bending takes place hence we get more deflection against bending stress. Also normal stress increases due to increase in span since more load is involved. Width of deck slab is kept constant and span …
