What is effective flexural stiffness?

The effective flexural stiffness of a structural concrete column is significantly affected by cracking along its length and by inelastic behavior of the concrete, reinforcing steel, and structural steel.

How can flexural rigidity be increased?

As we increase the value of flexural rigidity the strength of the beam to resist bending also increases. The flexural rigidity of components can be increase by raising the moment of inertia of cross-section or by choosing the material with a higher modulus of elasticity.

What does flexural rigidity indicate?

Flexural rigidity is defined as the force couple required to bend a fixed non-rigid structure by one unit of curvature, or as the resistance offered by a structure while undergoing bending.

How is stiffness related to flexural rigidity?

Stiffness (or rigidity) is a property of a polymers that is described by Flexural modulus or bending modulus of elasticity. It is therefore one of the most important properties of solid materials. Hence, the ratio of stress to strain is a measure of the flexural modulus.

What are the factors affecting flexural rigidity of a beam?

Flexural rigidity of a plate (e.g. the lithosphere) The flexure of the plate depends on: The plate elastic thickness (usually referred to as effective elastic thickness of the lithosphere). The elastic properties of the plate. The applied load or force.

What determines material stiffness?

The stiffness of a component means how much it deflects under a given load. This depends on the Young’s modulus of the material, but also on how it is loaded (tension, or bending) and the shape and size of the component.

What affects stiffness?

Stiffness is closely related to elastic or flexible materials. The more flexible a material is, the lesser the stiffness. In general, stiffness is the total measure of the amount of deflection caused by the load on the material. Engineers often associate a value known as Young Modulus “E” for Stiffness.
