Accuracy and effectiveness are paramount in any contemporary civil engineering activity, particularly when it comes to structural design. To facilitate both engineers and students, we have provided a free Beam Design Excel sheet with which the complex beam design process can be simplified under different loading conditions.
What This Beam Design Excel Sheet Covers
- Bending moment and shear force diagrams for simply supported, cantilever, and continuous beams under dead, live, and point loads
- Required flexural reinforcement (top and bottom steel) at critical sections based on the calculated bending moment
- Shear reinforcement (stirrup spacing) checks against the factored shear force at the critical section
- Deflection check against code-specified span/depth or allowable deflection limits
- Development length and bar cutoff points for the longitudinal reinforcement
- Section adequacy check comparing the provided beam depth and width against the design moment capacity
Design Inputs Required
- Beam span, support conditions, and overall depth and width
- Dead load, live load, and any point or partial loads acting on the beam
- Concrete compressive strength (f'c) and reinforcement yield strength (fy)
- Concrete cover to reinforcement
- Exposure condition, if deflection or crack-width limits apply
- Bar sizes available for longitudinal and shear reinforcement
Applicable Design Codes
The design checks in this sheet follow the reinforced concrete beam design provisions of ACI 318, covering flexural design, shear design, and serviceability (deflection) requirements for cast-in-place concrete beams.
Who Should Use This Tool
This tool is intended for structural engineers carrying out routine beam design on building projects, as well as engineering students who want to see how bending moment, shear, and reinforcement calculations come together in a single worked example.

Manually checking bending moment, shear, and deflection for every beam on a project is time-consuming and leaves room for arithmetic errors. This Excel sheet automates the standard reinforced concrete beam design workflow, from load input through to final reinforcement selection, so you can size beams consistently across a project and spend your review time on the cases that actually need engineering judgment. Download the free sheet above and adapt it to your own project loads and section sizes.
