The nominal shear stress should not exceed the maximum shear strength of concrete as given in table 20 of IS: 456 to avoid compression failure. section as displayed in following figure. The following formula is used: If the normal stresses on a structure are 15 psi in the x-direction and 40 psi in the y-direction with a total shear stress of 75 psi, then the center of the Mohr's circle and the maximum shear stress can be calculated. Maximum stress theory states that the shear forces on an element will vary at different cross-sections. This is the simplest practice to test the work piece under torsion. Thus the object develops a resistance to avoid the transverse shear. The probably most commonly used formula including the cross-sectional area is Navier's formula, which calculates the stress in any point of a cross-section due to bending and axial forces. On the cylinder center (r=0). in Civil Engineering back in 2011. Statement of Maximum shear stress theory: The maximum shear stress theory says that failure will occur when the maximum shear stress exceeds the shear stress at uniaxial loading. Create your account.
