Resources in this section
- TMT Steel Bars Guide→
Understand TMT steel bars used in RCC construction, including common bar sizes, Fe 415, Fe 500, Fe 500D, Fe 550 grades, unit weight formula, applications, standards, storage, bending, and common site mistakes.
- Steel Quantity Estimation for RCC Slabs→
Learn how to estimate steel quantity for RCC slabs, including slab reinforcement spacing, bar diameter, cover, cutting length, unit weight formula, thumb rules, and common site mistakes.
- Beam Reinforcement Guide→
Complete guide to RCC beam reinforcement per IS 456:2000 and SP 34. Covers tension and compression bars, stirrup spacing, minimum and maximum steel percentages, clear cover, detailing rules, bar bending schedule, and common reinforcement mistakes.
- Development Length Guide→
Complete development length (Ld) reference for RCC construction per IS 456:2000 Table 65. Covers all bar diameters, steel grades (Fe 415, Fe 500, Fe 550), and concrete grades (M15 to M40) — with worked examples for beams, slabs, columns, and footings, plus anchorage, lap splice, and hook equivalence rules.
- TMT Bar Weight Chart→
Complete TMT bar weight chart for all standard diameters 6mm to 40mm per IS 1786:2008. Covers unit weight (kg/m), weight per 12m rod, total weight formulae, bundle quantities, bar bending schedule calculations, and IS 1786 mass tolerance limits.
- Bar Bending Schedule (BBS) Guide: Cutting Length, Bend Deduction, and Hooks→
Practical guide to preparing a bar bending schedule — why cutting length is shorter than center-line length, standard bend deduction factors by angle, hook allowance, lap length, and worked examples for a stirrup and a cranked bar.
