सही: ० / ०
-
A soil has a porosity of 0.4. Its void ratio is about:
सही उत्तर: घ) 0.67
e = n/(1 − n) = 0.4/0.6 ≈ 0.67.

Talus, the loose rock debris accumulated at the foot of steep hill slopes, is an example of:
सही उत्तर: ख) Colluvial deposit
Colluvium (talus) is moved downslope mainly by gravity and collects at the base of slopes, as commonly seen along Nepal's hill roads.

-
Soil formed and remaining at the same place where the parent rock weathered is called:
सही उत्तर: ग) Residual soil
Residual soils stay over their parent rock; alluvial, colluvial and lacustrine soils are transported by water, gravity and lake action respectively.

Loess is a soil deposit transported and deposited mainly by:
सही उत्तर: ख) Wind
Loess is a uniform, silt-sized aeolian (wind-blown) deposit.

The 'short column effect' in earthquakes, as seen in columns partially restrained by partial-height infill walls, causes:
सही उत्तर: ग) Brittle shear failure because the short effective height attracts large shear
A shortened free height makes the column much stiffer, so it attracts large shear force and tends to fail in brittle shear.

The dead load per square metre of a 150 mm thick RCC slab (unit weight 25 kN/m³) is:
सही उत्तर: घ) 3.75 kN/m²
Self-weight = thickness × unit weight = 0.15 × 25 = 3.75 kN/m².

A 'soft storey' in a building, often seen in ground floors left open for parking or shops, is a storey whose:
सही उत्तर: ख) Lateral stiffness is much less than that of the storey above
An open ground storey with infilled upper floors has much lower lateral stiffness, concentrating deformation and causing collapse in earthquakes.

-
The 'strong column - weak beam' concept in earthquake-resistant design aims to ensure that:
सही उत्तर: ख) Plastic hinges form in beams rather than in columns
Hinging in beams keeps the columns elastic and avoids a storey (soft-storey) collapse mechanism.

-
In ductile detailing of RC frames for earthquake resistance (IS 13920), the ends of stirrups and ties are bent with a hook of:
सही उत्तर: क) 135°
135° hooks embedded in the core keep stirrups anchored even after cover spalls during an earthquake.

As per IS 875 (Part 2), the imposed (live) load on floors of dwelling (residential) rooms is:
सही उत्तर: ख) 2.0 kN/m²
IS 875 Part 2 prescribes 2.0 kN/m² uniformly distributed imposed load for residential dwelling floors.
