Question 1

What is the primary difference between a 'one-way slab' and a 'two-way slab'?

Accepted Answer

Direction(s) in which bending moments are developed

Answer

A one-way slab bends in a single direction, while a two-way slab bends in both directions when supported on all four sides.

Question 2

Which phenomenon causes long-term deflection in concrete structures beyond initial elastic deflection?

Accepted Answer

Creep and shrinkage

Answer

Creep (deformation under sustained load) and shrinkage (volume reduction as concrete dries) both contribute to long-term deflection.

Question 3

What is the purpose of a 'weep hole' in a masonry retaining wall?

Accepted Answer

Relieve hydrostatic pressure behind the wall

Answer

Weep holes allow water to drain from behind the retaining wall, preventing buildup of hydrostatic pressure that could cause failure.

Question 4

In steel construction, what is the 'effective length factor' (K) used to determine?

Accepted Answer

Column buckling capacity based on end conditions

Answer

The effective length factor K accounts for end restraint conditions to determine the effective buckling length of a column.

Question 5

What does 'liquefaction' refer to in geotechnical engineering?

Accepted Answer

Saturated loose sand behaving like a liquid during earthquake shaking

Answer

Liquefaction occurs when saturated loose granular soil loses shear strength due to earthquake-induced pore pressure increase, causing it to behave like a liquid.
