What is Design Bending Moment?

Design bending moment refers to the maximum bending moment that a structure or structural element is expected to experience under the worst anticipated loading conditions during its design life. Bending moment is a measure of the internal forces that are generated in a structure or structural element when it is subjected to a load or loads that cause it to bend. The design bending moment is determined by considering the loads that the structure is expected to experience, as well as its geometry, material properties, and other relevant factors.
The design bending moment is an important parameter in the design of structures such as beams, columns, and frames, as it affects their strength and stiffness. It is usually determined through structural analysis and is used to select appropriate structural members and to verify their adequacy for the expected loads.
