Calculation Modules
The core of ENERCALC is the calculation modules. Dating back to 1983 when our first software released as a set of spreadsheet templates, we design our modules to be “fill-in-the-blanks” style interactive programs. Just type in a value and instantly the resulting analysis or design is there to review.
The spreadsheet basis was given up 15 years ago because of its limitations and our software is 100% in-house developed specifically for the engineering tasks it must perform.
All modules in Version 6 conform to the 2006 IBC, 2007 CBC, 2005 ASCE, ACI 318-05, ACI 530-05, 13th Edition AISC and 2005 NDS.
Here’s a quick view of one of the calculation modules for footing design:

Currently included are modules for:
- Beam design in steel, composite steel & concrete, concrete, wood and masonry lint. Single & multi-span conditions with extensive loading and load combinations with variable compression edge slenderness are included.
- Column design in steel, concrete, wood and masonry. Biaxial design is provided for the first three and all masonry columns are designed using axial/bending interaction analysis. Concrete columns can be any shape with any rebar layout! Extensive loading (both lateral and vertical) is allowed along with mid-height axial loads.
- Foundation design is provided for general rectangular footings, combined footings, wall footings and "beam on elastic foundation" resting on soil (which are analyzed with our FEM solver).
- Wood Ledgers, pile groups, bolt groups, point loads on slabs, rebar embedment tables
- Slender concrete and masonry walls can be designed for out-of-plane loads using P-Delta analysis and can consider one & two stories, “reveals”, parapets, thermal effects, completely variable lateral loading, and varying base fixity.
- Generate geometric section properties of builtup sections
- Analyze a rigid diaphragm with up to 160 walls/beams/other elements as lateral force reisting elements. Program can rotate loads in all directions or apply in defined directions.
- Embedded pole footings.
- Two dimensional frame analysis with design available in steel and wood.
- Cantilevered Retaining Wall design using multiple material stem sectionsm surcharges, adjcaent footing loads and many more capabilities.
- Concrete, wood & masonry shear walls. Either solid multi-story walls or walls with perforations!
- Many more modules are under redevelopment to provide greatly enhanced capabilities over those in our prior versions. New modules released regularly as part of the Maintenance & Support Program.
The calculation module list is an ever expanding set of structural calculations that provide design for the elements of a building. And as requests are received from our users we develop additional modules…..and make use of the proven steel, concrete, timber, finite element analysis, and other engineering “solvers” we have developed.
