Critical section for shear in beams

WebIt was shown is Section 3.5.3 that this cannot always be done. For beams with all critical sections in Class 1 or 2, uniform spacing is allowed by Eurocode 4 along each critical length, which is a length of the interface between two adjacent critical cross-sections. These are defined as sections of maximum bending moment. supports. WebShear Design of Beams CE 470 -Steel Design Class By: Amit H. Varma Shear Strength nBeam shear strength is covered in Chapter G of the AISC specifications. Both rolled shapes and welded built-up shapes are covered. nRolled shapes is the focus here. Built-up shapes, commonly referred to as plate-girders are beyond the scope of our course.
