Design 13 specialized structural elements with automatic vector drawings (S-01 to S-07), bar bending schedules, and step-by-step PDF reports.
No account required. Instant in-browser calculations.
Complete Design Package
From a floor plan sketch to slab reinforcement layout, beam design, column schedule, and footing details — in one click. Sheet S-01 through S-07 included.
Multi-Code Engine
ACI 318-19 (US/Middle East/Pakistan), IS 456 (India), Eurocode 2 (Europe/Gulf), and ACI 350-06 (Liquid Tanks). Switch codes per module seamlessly.
Vertical Load Cascading
Automated load transfer down the building hierarchy: Slab end reactions → Beams → Column axial/moment loads → Footings & Pile Caps.
Complete Structural Suite
Every primary reinforced concrete, geotechnical, masonry, and environmental liquid-retaining element.
Whole-Floor Slab Grid
Continuous multi-bay floor grids with openings, drop panels, EFM/PCA coefficients, and S-01 to S-07 drawings.
RC Beam Studio
Singly/doubly reinforced rectangular & T-beams, multi-span continuity, flexure, shear, torsion, and BBS.
Column Design Studio
Tied and spiral columns, biaxial bending via Bresler Contour, full P-M-M interaction curves, and slenderness.
RC Staircase Studio
Dog-legged and open-well staircases, tread/riser geometry, flight slab flexural design, and step detailing.
Foundation Design
Isolated pad, combined two-column, and continuous strip footings with q_max bearing and punching shear (d/2).
Pile Cap Foundation
2 to 5 pile rigid cap reaction distribution, ACI 318 Ch. 23 Strut-and-Tie flexure, and punching checks.
Pile Foundation Studio
Layered soil Qp + Qs capacity (Skempton/Reissner), ACI 318 circular shaft reinforcement, and inverse depth solver.
Brick Masonry Footing
Plain and reinforced stepped brick masonry wall footings with load distribution and masonry shear checks.
Bearing Capacity & Settlement
Ultimate & allowable soil bearing capacity (Terzaghi 1943 / Meyerhof 1963) with elastic and consolidation settlement.
Laterally Loaded Pile
Ultimate lateral load capacity for single piles in sand & clay under horizontal or eccentric head loading.
Retaining Wall Studio
Cantilever T-walls, mass concrete gravity walls, and counterfort walls with Rankine earth pressure and sliding/overturning FOS.
RC Water Tank Studio
Underground & overhead liquid tanks with environmental durability factors (Sd = 1.3/1.65), ring tension T=p·R, and crack control.
RC Swimming Pool
Pool Full/Dry and Pool Empty/Wet load cases, buoyancy uplift factor of safety ≥ 1.2, wall-floor joint, and crack control w ≤ 0.1 mm.
