Three forces effect the structural design parameters of loads: Because no material can withstand an infinite load, engineers calculate the “bending moment” when considering external forces. A beam’s capacity to withstand load is a computation that aids in determining the building’s overall structural soundness. As a result, while designing a structure for optimal stability, engineers must consider both. Capacity vs demandĭead loads and live loads both act simultaneously on structures, changing how all its components interact. Damage can happen due to bending whenever the bending stress exceeds the element’s ultimate strength. Examples of loads can for instance be live load (the people or objects in the building), dead load (the weight of the structure itself), and environmental loads (snow load, wind load and earthquakes). To keep the stability of structures, resistance to bending moment is therefore crucial. The design of structures incorporates the effects of loading. We also provide equations and calculators for common beam configurations. In this article, we discuss the concepts around bending moment.
