Structural Engineering Calculation Software


It’s simple…

ENERCALC SEL provides structural engineers with a single, consistent, easy-to-use source for the common design and analysis tasks common to all buildings.

From composite beams to retaining walls, your business will be more productive than you thought possible!

We believe that the simple calculations for elements of a building are the most common, repetitive and tedious calculations an engineer performs. This is evident in the multitude of spreadsheets most engineers have developed for their most routine calculations.


Imagine flying into a city

What you see is hundreds of square miles of small, low rise buildings, each needing a remodel or will be used as the site of a future new building.

Do high rise buildings dominate the landscape? No, only in the small circled area.

What you will see is that 99% of the land area is filled with low rise buildings needing simple, yet critically important, structural calculations.


This is the work ENERCALC excels at.

A consistent tool for the bulk of your work

You DO NOT need that very impressive fully-integrated multi-level building design system for 99% of building design analysis.

What you need is a tool specifically designed to handle the detailed tasks of designing the small elements of these buildings: ENERCALC.

Simply call up one of the dozens of ENERCALC modules and you can effortlessly enter your design data and watch as the calculations unfold before you in real-time.

With that clarified, what do we provide that will help you?

Our central concept is that of a fill-in-the-blanks “calcpad” style form. ENERCALC SEL gives you the best of 40+ years of experience. Simply call up one of the dozens of modules and you can effortlessly enter your design data and watch as the calculations unfold before you. This interactive system is the best of both spreadsheet and programmed user interfaces. Please download the Evaluation Version for a complete usage experience.
