Long and short spans of a two way slab are ly and lx and load on the slab acting on strips parallel to lx and ly be wx and wy respectively. According to Rankine Grashoff theory (wx/wy) = (ly/lx)⁴ (wx/wy) = (ly/lx) (wx/wy) = (ly/lx)² None of these TRUE ANSWER : ? YOUR ANSWER : ?
A singly reinforced concrete beam of 25 cm width and 70 cm effective depth is provided with 18.75 cm² steel. If the modular ratio (m) is 15, the depth of the neutral axis, is 20 cm 25 cm 30 cm 35 cm TRUE ANSWER : ? YOUR ANSWER : ?
A pre-stressed concrete member is preferred because All listed here Removal of cracks in the members due to shrinkage Large size of long beams carrying large shear force need not be adopted Its dimensions are not decided from the diagonal tensile stress TRUE ANSWER : ? YOUR ANSWER : ?
In testing a pile by load test, pile platform is loaded with one and half times the design load and a maximum settlement is noted. The load is gradually removed and the consequent rebound is measured. For a safe pile, the net settlement (i.e. total settlement minus rebound) per tonne of test load should not exceed 20 mm 25 mm 10 mm 15 mm TRUE ANSWER : ? YOUR ANSWER : ?
The toe projection of foundation slabs is taken Below ground surface As one sixth of overall height of the wall As one third of the base Equal to heel slab TRUE ANSWER : ? YOUR ANSWER : ?
If A is the area of the foundation of a retaining wall carrying a load W and retaining earth of weight 'w' per unit volume, the minimum depth (h) of the foundation from the free surface of the earth, is h = (W/Aw) [(1 + sin φ)/(1 + sin φ)] h = (W/Aw) [(1 - sin φ)/(1 + sin φ)] h = (W/Aw) [(1 - sin φ)/(1 + sin φ)]² h = √(W/Aw) [(1 - sin φ)/(1 + sin φ)]² TRUE ANSWER : ? YOUR ANSWER : ?
The diameter of main bars in R.C.C. columns, shall not be less than 10 mm 15 mm 11 mm 12 mm TRUE ANSWER : ? YOUR ANSWER : ?
In a beam the local bond stress Sb, is equal to Leaver arm/(Shear force × Total perimeter of reinforcement) Leaver arm/(Bending moment × Total perimeter of reinforcement) Total perimeter of reinforcement/(Leaver arm × Shear force) Shear force/(Leaver arm × Total perimeter of reinforcement) TRUE ANSWER : ? YOUR ANSWER : ?
If L is the effective span of a R.C.C. beam which is subjected to maximum shear qmax at the ends, the distance from either end over which stirrups for the shear, are provided, is (L/3) (1 - 5/qmax) (L/2) (1 - 5/qmax) (L/2) (1 - 2/qmax) (L/2) (1 - 3/qmax) TRUE ANSWER : ? YOUR ANSWER : ?
