Beam on Elastic Foundation Calculator Demo — Structural Engineering Analysis Tool
Structural engineers often deal with beams supported by continuous elastic foundations, such as soil or bedding materials. The Beam on Elastic Foundation model is a fundamental approach to analyze how beams deflect, bend, and distribute loads when resting on elastic supports. This Beam on Elastic Foundation Calculator Demo demonstrates how SpreadsheetWeb transforms complex Excel-based engineering models into fully interactive web applications for instant and accurate analysis.
What Is a Beam on Elastic Foundation?
A beam on elastic foundation (BEF) is an analytical model used to describe the behavior of a beam supported by a continuous, linearly elastic medium, commonly soil, subgrade, or compressible bedding. The foundation reacts proportionally to beam deflection, represented by the modulus of subgrade reaction (k).
This model is widely used in the design of pipelines, pavements, railroad tracks, bridge decks, and other structural systems resting on deformable supports.
What the Calculator Does
The Beam on Elastic Foundation Calculator computes beam deflections, shear forces, and bending moments for given material and loading parameters. It provides quick insight into how beam stiffness, foundation modulus, and applied loads interact.
- Inputs include:
- Beam length, stiffness (EI), and cross-sectional properties
