Design tools
Trusted by engineers, architects and builders in more than 150 countries.
Beam Designer
Single and multi-span steel and wood beams, including flitch beams and engineered lumber.
Column Designer
Steel W, HSS and pipe columns and wood posts, glulam, LVL and PSL under axial load and bending.
Concrete Footing Designer
Spread footings checked for bearing, one-way and two-way shear, flexure and bar development.
Anchor Bolt Designer
Threaded rods, headed bolts, headed studs and hooked bolts, with or without seismic provisions.
Frame Designer
2D steel frames and trusses: reactions, bending moment, shear, axial force and deflection.
Wind Load Calculator
Low-rise building wind pressures to ASCE 7-22 or 7-16, by zone for frames, walls and roofs, with a window and door schedule.
Framing calculators
Free span calculators for framing a house or a deck, checked to NDS 2018. Start at the roof and work down: each result opens the next calculator with its spans and loads filled in.
Rafter span calculator
How far 2x6 to 2x12 rafters span at any slope, for roof live load or snow.
Header span calculator
What size header a door or window needs, with jack studs, by building width and floors above.
Floor joist span calculator
How far floor joists span at 12, 16 and 24 in apart.
Wood beam span calculator
Solid and built-up beams that carry the joists or replace a wall.
Deck framing calculator
Joists, beams, posts and footings for a whole deck, with a material list.
Deck joist span calculator
How far treated deck joists span, with or without an overhang.
Beam Designer
Design multi-span beams with complex loads. An interactive drawing area lets you design beams in minutes. Use the free version as much as you like.
AISC 360-16 & 2018 NDS Design
Steel and wood design with ASCE 7-16 LRFD, ASCE 7-16 ASD and 2018 NDS design checks and load combinations.
Steel, Wood and Custom Shapes
Choose from an extensive shape library of common steel, lumber and engineered lumber shapes, including flitch wood beams. Analysis and capacity check for custom shapes.

Design a Beam
Column Designer
Check steel and wood columns under axial load and bending, with every load combination worked out. Every steel shape and sawn post is free.
AISC 360-16 & 2018 NDS Design
Compression, bending about both axes, shear and combined load and bending, with moments increased for the column's bow. ASCE 7-16 LRFD and ASD load combinations, with wind and earthquake both ways.
Steel Shapes, Posts and Engineered Wood
W shapes, square, rectangular and round hollow structural sections (HSS), and pipe; sawn posts from 4x4 to 8x8; glulam, LVL and PSL. Open a column straight from the beam designer's reactions, then pass its loads on to the footing designer.
Want to see the math? Follow three steel column examples worked step by step.
Design a Column
Concrete Footing Designer
Quick and easy concrete spread footing design.
ACI 318-19 Concrete Footings
Design footings based on allowable bearing pressure, one-way shear, two-way shear, flexure strength, reinforcement bar development, column bearing and footing bearing loads.
Comprehensive Design Parameters
Include dead loads, live loads, floor slab weight, floor load, fill (overburden) loads and steel reinforcement configurations.
