Q3. Four columns of building are to be located within a plot size of 10m ×10m . The
expected load on each column is 400 kN. Allowable bearing capacity of soil
deposit is 2 100kN / m2 . The type of foundation to be used is
Answer : Option A
Explaination / Solution:
Load on each column = 400kN
Bearing capacity of soil = 100 kN/m2
Area of each footing required = 400/100m2 = 4m2
Total area required = 4×4 = 16m2
Foundation area/Plot area = 16/100 = 16%
If the foundation area is less than 40% of plot area, then isolated foundation is
suitable.
Q4. The “Plane section remain plane” assumption in bending theory implies
Answer : Option A
Explaination / Solution:
No Explaination.
Q5. Two steel column P (length L and yield strength fy = 250MPa) and Q (length 2L
and yield strength fy = 500MPa) have the same cross-section and end condition.
The ratio of buckling load of column P to that of column Q is
Answer : Option D
Explaination / Solution:
Buckling load,
Q6. Maximum possible value of compaction factor for fresh (green) concrete is
Answer : Option B
Explaination / Solution:
No Explaination.
Q7. For the fillet weld of size ‘s ’ shown in the adjoining figure the effective throat thickness is
Answer : Option B
Explaination / Solution:
No Explaination.
Q8. A 16 mm thick plate measuring 650mm X 420 mm is used as a base plate for an ISHB 300 column subjected to a factored axial compressive load of 2000 kN. As per IS 456-2000, the minimum grade of concrete that should be used below the base plate for safely carrying the load is
Answer : Option A
Explaination / Solution:
No Explaination.
Q9. Consider a reinforcing bar embedded in concrete. In a marine environment this bar undergoes uniform corrosion, which leads to the deposition of corrosion products on its surface and an increase in the apparent volume of the bar. This subjects the surrounding concrete to expansive pressure. As a result, corrosion induced cracks appear at the surface of concrete. Which of the following statements is TRUE?
Answer : Option C
Explaination / Solution:
No Explaination.
Q10. The cross-section of a thermo-mechanically treated (TMT) reinforcing bar has
Answer : Option C
Explaination / Solution:
No Explaination.
