Could you please elaborate on the mechanisms that lead to the failure of an I-beam? Are there specific types of stress or loading conditions that are more likely to cause it to fail? Additionally, how does the material composition and structural design of an I-beam impact its resistance to failure? Understanding these factors is crucial for engineers to ensure the safety and durability of structures built with I-beams.
Components within the beam's construction, such as stiffeners, are designed to provide additional stability to the web. However, these components themselves are susceptible to buckling or yielding under high loads.

In the realm of structural engineering, slender webs are prone to failure modes that involve buckling and tension field action. Buckling occurs when the web's slenderness leads to instability, resulting in rippling or waving patterns that compromise its integrity.

Tension field action, a distinct failure phenomenon, arises when the web experiences tension across its width, causing it to behave more like a membrane than a traditional beam. This behavior, though, does not fully explain all aspects of web failure.

Alongside tension field action, the stiffness of the flanges plays a crucial role in resisting shear failure. The flanges, being relatively thicker and stronger, contribute significantly to the overall resistance of the beam against shearing forces.
