A floor slab of thickness, $$t$$ is cast monolithically transverse to a rectangular continuous beam of span $$L$$ and width $$B.$$ If the distance between two consecutive points of contraflexure is $${L_0},$$ the effective width of compression flange at a continuous support is

A reinforced concrete member is subjected to combined action of compressive axial force and bending moment. If $${\varepsilon _{\min }}$$ is the least compressive strain in the member $${f_y},$$ the yield stress of steel and $${E_s},$$ the modulus of elasticity of steel, the maximum permissible compressive strain in concrete member will be

If $$\phi \, = \,$$ nominal diameter of reinforcing bar, $${f_s}\, = $$ compressive stress in the bar and $${f_{bd}}\, = $$ design bond stress of concrete, the anchorage length, $${L_a}$$ of straight bar in compression is equal to

The loss of prestress due to elastic shortening of concrete is least in

A uniformly distributed load intensity, $$w$$ acting on a simply supported prestressed concrete beam of span $$L,$$ producing a bending moment $$M,$$ at mid-span is to be balanced by a parabolic tendon with zero eccentricity at ends and eccentricity $$e,$$ at mid-span. The prestressing force required depends on

The maximum bending stress induced in a steel wire of modulus of elasticity $$200$$ $$kN/m{m^2}$$ and diameter $$1$$ $$mm$$ when wound on a drum of diameter $$1$$ $$m$$ is approximately equal to

In a real beam, at an end, the boundary condition of zero slope and zero vertical displacement exists. In the corresponding conjugate beam, the boundary conditions at this end will be:

A cantilever beam of span, $$'L'$$ is subjected to a downward load of $$800$$ $$kN$$ uniformly distributed over its length and a concentrated upward load $$P$$ at its free end. For vertical displacement to be zero at the free end, the value of $$P$$ is:
