Design Of Beams 1
Possible types of failures for beams are shown. Definition of Lateral torsional buckling is illustrated and showed by simple experiment using notebook. Graph is drawn to show relation between unbraced length and moment capacity of sections by defining plastic capacity of section, In elastic and Elastic critical buckling moment.
Design Of Beams
Lecture starts by reviewing stress-strain diagram of steel. This is followed by deriving yielding moment, and plastic moment for sections subject to bending moment. Elastic and plastic sections moduli are shown in addition to the shape factor, and links is presented between deflection, effectiveness, and shape factor of sections
