ENERCALC Structural Engineering Software
64 modules. One interface. Built the way you already think.
ENERCALC handles 90% of your structural engineering design work: beams, columns, foundations, walls, earth retention, wind, snow, seismic, and more. Steel, wood, concrete, masonry, and composite, all in the same project.
Small projects of 5 stories or fewer dominate the structures built nationwide. This is the work ENERCALC was built for.
Every module follows the same layout. Inputs on the left, results on the right. Change a value, watch it recalculate. The consistency means learning one module teaches you all of them, the same way muscle memory works in a sport you’ve trained for.
Your calculations, spreadsheets, PDFs, images, and reference docs all live together in one project file. No hunting through folders. No reassembling a project from scattered files and folders when you need to revisit it a year later.

Six fundamental properties of ENERCALC intended to make complex design work simpler and easier:
Diverse calculation
types & materials
Steel, wood, concrete, masonry, and composite in the same project. Switch materials without switching software. Beams, columns, walls, foundations, earth-retention structures, and analysis modules.
Easy Tabular Navigation
Every module follows the same layout: inputs on the left, results on the right. Learn one, you’ve learned them all
Real-time Graphics
See your design update in real time as you change inputs. Catch errors visually before they reach a submittal.
Simple Intuitive Inputs
Fill in what you know. ENERCALC handles the code lookups, load combinations, and iteration
Detailed Calculations
Detailed intermediate values, Excel intermediate value exports, and more.
Project Based Organization
Group your calcs, spreadsheets, PDFs, images, and reference docs in one project file. No more hunting through folders
