ISRO Scientist Civil study plan

ISRO Scientist Civil · Give each week a clear focus.

8 weeks · About 8 hours per week

Week 1

Structural Engineering (Mechanics of Solids, Structural Analysis, Concrete and Steel Design)

  • Derive and apply stress-strain relations, principal stresses, and Mohr's circle to solve at least 15 numerical problems on combined bending and shear

  • Analyse determinate beams and trusses using influence lines and unit-load (virtual work) methods, computing deflections by hand for 10 standard cases

  • Set up slope-deflection and moment-distribution solutions for 6 continuous beams and 4 plane frames, checking equilibrium at every joint

  • Summarise the IS 456 limit-state design philosophy (partial safety factors, exposure classes, nominal cover) into a one-page reference sheet

Your checkpoint

A hand-written solution notebook of 30 solved structural analysis and mechanics problems with free-body diagrams and equilibrium checks, scored against a self-made answer key

Week 2

Structural Engineering (Mechanics of Solids, Structural Analysis, Concrete and Steel Design)

  • Design singly and doubly reinforced rectangular beams and one-way slabs to IS 456, verifying flexure, shear, and development length

  • Produce reinforcement detailing sketches for 5 beam and column sections including lap and anchorage zones

  • Design a short and a slender RCC column under axial load plus uniaxial bending using the interaction concept

  • Check 4 steel tension members, 3 welded/bolted connections, and 2 laterally supported beams against IS 800 limit states

Your checkpoint

A design portfolio of 12 RCC and steel elements with calculations, code clause citations, and detailing sketches

Week 3

Geotechnical Engineering (Soil Mechanics and Foundation Engineering)

  • Classify soils by ISCS and AASHTO using sieve and Atterberg data, and compute effective stress profiles with capillary and seepage effects

  • Determine shear strength parameters from direct shear and triaxial test data, and compute bearing capacity by Terzaghi and IS 6403 methods

  • Design a shallow footing for both bearing capacity and settlement, then compare against a pile-group capacity calculation

  • Evaluate slope stability by the Swedish circle method for 3 worked cases and interpret a flow net for a sheet-pile excavation

Your checkpoint

A geotechnical calculation set of 15 problems (index properties, consolidation, shear strength, bearing capacity, foundations) with a summary table of key formulas and assumptions

Week 4

Water Resources and Hydraulic Engineering (Fluid Mechanics, Hydraulics, Hydrology, Irrigation)

  • Solve 12 fluid statics and manometry problems and apply Bernoulli and momentum equations to pipe bends, nozzles, and orifices

  • Compute friction and minor losses in series and parallel pipe networks, and select a pump operating point from a system curve

  • Perform open-channel flow calculations using Manning and specific-energy concepts, including hydraulic jump and critical depth
