Web= unbraced length, E = modulus of elasticity, G = shear modulus, J = torsional constant, I y = weak axis moment of inertia and C w = warping constant. The first term under the radical in Eq.1 relates to the St. Venant torsional stiffness, while the second term within the radical reflects the warping stiffness of the beam. In the derivation of WebCritical Buckling Strength. 𝑘𝜋 2 𝐸 𝑡 2. 𝐹𝑐𝑟 =. 12 (1 − 𝑣 2 ) 𝑏. • This critical buckling strength indicates the stress limit of the plate to avoid the. buckling failure to occur. • This equation can be used in the design process to moderate the thickness of. the plate. • 𝑘 … Web• As size of beam is increasing, deflection of beam is decreasing. As the web opening move towards the center of beam,stress goes on decreasing and hence deflection is reduced [2]. Hence from this [2] paper if stiffeners are provided along the shear zone, stress can be controlled and shear deformation can be minimized. black tea tooth infection
