About this calculator
The Flecha Máx, Viga Biapoiada (distributed load) calculator is a useful tool for civil engineers and engineering students. It helps to calculate the maximum deflection of a bi-supported beam under distributed load.
The formula used by this calculator is based on beam theory, which is fundamental for the design of concrete and steel structures. The formula is: δ = 5qL⁴/(384EI), where δ is the maximum deflection, q is the distributed load, L is the beam width, E is the modulus of elasticity and I is the moment of inertia.
This calculator is useful in real cases, such as bridge and building design. It's worth remembering that the distributed load can vary depending on the location and application, and that the maximum deflection must be calculated carefully to avoid damage to the structure.
Frequently asked questions
What is the distributed load?
The distributed load is a force applied uniformly along the beam, such as the weight of a bridge or a building.
Why is it important to calculate the maximum deflection?
Calculating the maximum deflection is important to avoid damage to the structure, as the beam may bend too much and compromise the stability of the building.
What factors affect the distributed load?
The factors that affect the distributed load include the weight of the material, the beam width and the distance between the supports.
Can this calculator be used for other types of structures?
No, this calculator is specific to bi-supported beams under distributed load. For other structures, a different calculator or formula must be used.
