Marks 1

A simply supported, uniformly loaded, two-way slab panel is torsionally unrestrained. The effective span lengths along the short span (x) and long span (y) directions of the panel are $l_{x}$ and $l_{y}$, respectively. The design moments for the reinforcements along the x and y directions are $M_{ux}$ and $M_{uy}$, respectively. By using Rankine-Grashoff method, the ratio $M_{ux}/M_{uy}$ is proportional to

A slab panel with an effective depth of 250 mm is reinforced with 0.2% main reinforcement using 8 mm diameter steel bars. The uniform center-to-center spacing (in mm) at which the 8 mm diameter bars are placed in the slab panel is __________ (rounded off to the nearest integer).

Consider a doubly reinforced RCC beam with the option of using either Fe250 plain bars or Fe500 deformed bars in the compression zone. The modulus of elasticity of steel is 2 × 10⁵ N/mm² . As per IS456 : 2000, in which type(s) of the bars, the stress in the compression steel (f_sc) can reach the design strength (0.87 f_y) at the limit state of collapse?

Marks 5

The effective spans for a simple one-way slab system, with an overhang are indicated in the figure below. The specified ultimate design loads on the slab are $$6.0\,kN/{m^2}$$ and $$4.5\,kN/{m^2}$$ for dead loads and live loads respectively. Considering the possibility of live loads not occurring simultaneously on both spans, determine the maximum spacing (in $$mm$$ units) of $$8$$ $$mm$$ diameter bars required as bottom reinforcement in the span $$AB,$$ assuming an effective depth of $$125$$ $$mm.$$ Assume $$M20$$ concrete and $$Fe$$ $$415$$ steel.
