Beam Deflection Calculator
Calculate maximum deflection of simply supported beams
About this calculator
The Beam Deflection Calculator determines the maximum deflection of simply supported beams under various loading conditions. This tool is essential for structural engineers, architects, and construction professionals to ensure beams meet deflection limits and maintain structural integrity. By calculating maximum deflection values, users can verify that their beam designs comply with building codes and performance requirements, preventing excessive sagging that could compromise structural safety and functionality.
How to use
Enter your beam parameters including length, material properties (elastic modulus and moment of inertia), and applied loads. Select the appropriate loading condition from the dropdown menu (point load, uniform load, etc.). Click calculate to instantly determine the maximum deflection value and its location along the beam span.
Frequently asked questions
What is the deflection limit for beams?
Common deflection limits are L/360 for floors and L/240 for roofs, where L is the beam span length.
What factors affect beam deflection?
Beam deflection depends on load magnitude, span length, material stiffness (E), and cross-sectional properties (moment of inertia).
Can this calculator handle multiple load types?
Yes, the calculator supports various loading conditions including point loads, uniform loads, and triangular distributed loads.
