Since 1998 we have offered Excel tools to assist structural engineers in analyzing and designing bridge and building components. As engineers ourselves, we focus on technical accuracy, productivity, ease of use, and clarity of presentation.
The most intuitive continuous beam analysis software available. Supports static and moving loads, support settlements, non-linear analysis on elastic foundations, plastic moment redistribution, and influence line analysis. Models elastic springs, column supports, in-span hinges, and variable beam stiffness.
ProfessionalComputes elongation and prestress losses in 3D post-tensioned tendons, accounting for friction and anchor set.
ProfessionalDesigns reinforced concrete members to US, Canadian, and Australian building and bridge codes. Generates P-M interaction diagrams, evaluates shear and torsion resistance, and checks crack control under service loads.
Version 2026.04 — Updated to ACI 318-25 and AASHTO LRFD 10th Ed. 2024. Improved presentation and performance.
ProfessionalEurocode 2 edition of ShortCol for axial and flexural capacity and crack width of reinforced concrete members. Features a wizard-style interface.
ProfessionalCalculates shear capacity of eccentrically loaded bolt groups per AISC LRFD, using elastic and instantaneous center of rotation methods. Supports standard and irregular layouts.
ProfessionalComputes resistance of welded connections under in-plane and out-of-plane loads per AISC, using elastic and instantaneous center methods. Generates standard or irregular weld patterns.
ProfessionalCalculates structural properties of general cross-sections: area, centroid, moments of inertia, shear center, and warping moment of inertia of thin-walled sections. Sections defined by nodes or layered geometry.
ProfessionalGenerates load combinations and identifies extreme force envelopes for structural members, accounting for dual load factor alternatives.
ProfessionalCalculates reinforced and prestressed concrete shear and torsion capacity per AASHTO LRFD Bridge Code, 2024 edition.
ProfessionalGenerates influence lines for shear, bending moment, and reactions in continuous beams. Calculates force envelopes from custom moving loads. A highly educational tool with clear insight into structural behavior.
FreeCalculates lateral earth pressure on retaining walls from multiple surcharge area loads. Useful for evaluating pressures from nearby vehicles and stationary loads.
FreeExcel-based Sudoku puzzle. Creates puzzles, provides helpful notations and hints when you get stuck. Lots of fun for analytical minds.
FreeSolves the classic travelling salesman problem — finding the shortest cyclical itinerary through a set of cities.
FreeNamed after the TV show Let's Make a Deal: you pick one of three doors, the host reveals a goat, and you may switch. Should you? A simple puzzle with a surprising answer that stumped many experts.
