// personal study reference — civil engineering

Notes, formulas and working models,
drawn out properly.

A single place to keep structural, geotechnical and transportation notes — built with small interactive tools instead of static PDFs, so the concepts are easier to actually check.

SPAN 18.0 m — WARREN TRUSS

Sheet Index

Every subject gets its own reference sheet — same structure every time: key formulas, worked examples, code clauses.
S — 101

Structural Analysis

Beam and frame analysis, shear force / bending moment diagrams, deflection, influence lines, IS 800 & ACI 318 clause references.

G — 201

Geotechnical Engineering

Soil classification, bearing capacity, consolidation settlement, slope stability, foundation design checks.

T — 301

Transportation Engineering

Pavement design (flexible & rigid), geometric design of highways, traffic flow fundamentals, intersection design.

E — 401

Environmental Engineering

Water treatment unit processes, wastewater design flows, air quality basics, solid waste management.

C — 501

Construction Management

CPM/PERT scheduling, estimation and costing, quality control, project delivery methods.

SU — 601

Surveying

Leveling, traversing, total station and GPS basics, contouring, area and volume computation.

Beam Lab

A simply supported steel beam, 6 m span, central point load. Drag the load and watch the deflected shape update.
P = 40 kN
2.70 mm
midspan deflection
δ < L/360 (16.7 mm) — within limit
Assumes: L = 6 m, E = 200 GPa, I = 200 × 10⁶ mm⁴ (ISMB 400 approx.).
δ = PL³ / 48EI · deflection curve shown at 12× visual scale.

What else belongs here

The parts worth adding next, once the core notes are in place.

Code & standards lookup

Searchable clause references from IS 456, IS 800, IS 1893, so you're not digging through PDFs mid-problem.

Previous year papers

Tagged by subject and year, with worked solutions attached rather than answer keys alone.

Detail library

Simple sketches of standard details — footing, beam-column joint, staircase — for quick revision before exams.

More live calculators

Concrete mix design, earthwork cut/fill volumes, column slenderness checks — same interactive format as the beam lab.

Site visit log

Photos and notes from any site visits or internships, organised by what was learned rather than just dated entries.
