Analytical solution for large deflection of Reissner׳s beam on two supports subjected to central concentrated force

• Analytical solution of large deflection of Reissner׳s beam subject to three point bending is present.
• Three type of supports are discussed: simple supports, roller supports and hinged supports.
• The solution for each type of support is illustrated by load-deflection diagrams.

In this article, an analytical solution for the deflection of a Reissner׳s beam under a force acting at the midpoint between two supports is given. Three types of beams are considered: simply supported, roller supported, and hinge supported. The solution for each type is illustrated by load-deflection diagrams, tables of reference values, and examples of deformed beam shapes.
