Fixed support develops support moment.

Fixed support is a type of support that is commonly used in structural engineering. It restricts both translation and rotation of the supported element. When a load is applied to a fixed support, it resists both vertical and horizontal movement, as well as any rotation. This resistance to rotation leads to the development of a support moment.

Support moment refers to the bending moment that develops at a fixed support due to the applied load. It is a measure of the internal forces and stresses within a structure. The support moment is caused by the reaction forces at the fixed support, which counteract the external load.

The support moment can be calculated using the principles of statics and structural analysis. By applying equilibrium equations and considering the geometry and loading conditions, engineers can determine the magnitude and distribution of the support moment.

The support moment is an important consideration in the design of structures, as it affects the overall stability and strength of the system. It determines the maximum bending and shear stresses in the supported element and influences the selection of materials and dimensions for structural members.

The support moment also affects the deflection of the structure. Higher support moments result in larger deflections, which can impact the serviceability and functionality of the structure.

In summary, a fixed support develops a support moment when subjected to an applied load. This moment is caused by the reaction forces at the fixed support and is an important factor in the design and analysis of structures.
