ISRO Scientist Civil case studies

ISRO Scientist Civil · Put your knowledge to work in context.

The ISRO Scientist/Engineer 'SC' Civil recruitment examination is the entry route into scientific and engineering posts at the Indian Space Research Organisation for civil engineering graduates. It is aimed at candidates who hold a first-class BE/BTech (or equivalent) in Civil Engineering and who want to work on launch-pad structures, ground infrastructure, water and environmental systems, and site facilities rather than on satellite payloads themselves. The ISRO Scientist Civil case studies are 5 cases and about 4,281 words.

RCC Beam with Excess Deflection, Flexural Cracks and a Late Load Addition

A G+4 office block in Bhopal uses RCC beam–slab floors to M25/Fe500. One interior beam is 300 mm wide × 600 mm deep with an 8.0 m clear span; it carries a 150 mm slab (tributary width 4.0 m) and a 230 mm brick partition along part of its length.

Raft on Soft Clay: Bearing Capacity Versus Settlement and the Ground Improvement Decision

A six-storey RC framed residential block, 30 m × 20 m in plan, is to be founded on a raft at 2.0 m depth. The profile is 3 m of recently placed sandy fill (γ = 18 kN/m³) over 8 m of soft-to-medium clay (SPT N = 4–6, w = 42%, e = 1.15, Cc = 0.32, cv = 2.0 m²/yr, cu ≈ 28 kPa) resting on dense sand with N 50.

Unlined Distributary: Verifying the Regime Section, Diagnosing Siltation and Judging a Lining Proposal

An 18 km unlined distributary takes off from a main canal with a design head discharge of 15 m³/s to command 12,000 ha. It was designed on Lacey's regime equations with silt factor f = 1.0 and side slopes 0.5H:1V, and built to the approved bed width and depth.

Activated Sludge Plant Losing Biomass in the Monsoon

A 30 MLD conventional activated sludge plant serves a mixed residential and textile-dyeing town. The aeration tank volume is 6,000 m³ with MLSS of 3,000 mg/L in the dry season, and there are two secondary clarifiers of 24 m diameter each.

Signal or Flyover: Justifying a Two-Phase Signal at a Four-Arm Intersection

A four-arm at-grade intersection on a state highway in a tier-2 city carries peak-hour flows of 1,150 PCU/h from the north, 950 from the south, 780 from the east and 640 from the west. Each approach has two lanes and the saturation flow is 1,800 PCU/h per lane.
