This chapter discusses the characteristics and behavior of unbraced rolled steel beams, focusing on various failure modes including lateral torsional buckling. Essential equations from the AISC for analyzing these scenarios are provided, along with governing moments in relation to beam length and support configurations. Additionally, the chapter covers fundamental concepts of torsion as related to structural engineering applications.
Unbraced rolled steel beams can experience lateral torsional buckling in the absence of lateral support.
The behavior of beams under torsion can be categorized into Saint-Venant's torsion and warping torsion.
AISC equations are utilized to analyze the flexural efficiency of beams and their response to various loads.
A failure mode in beams that occurs when they are not laterally supported, leading to instability.
A type of torsion where the cross-section remains plane during twisting, resulting in uniform torque across the length.
A torsional effect where lateral displacement occurs, resulting in bending of the flange under the application of torque.
Equations provided by the American Institute of Steel Construction to analyze and determine the behavior of steel structures under various loading conditions.
