Torsion in structures is something that is best avoided as far as possible. This is because the twisting of structural elements generates large internal forces which result in a significant increase in element sizes and possibly even change in form

At approximately 7pm that day, guests heard popping noises moments before the fourth-floor walkway fell into the second-floor walkway. Both walkway then fell to the ground killing 114 and severely injuring over 200 persons
Steel elements are often required to sustain tensile forces, these elements are referred to as tension members or tie. Example of tension members includes steel bracings in buildings, roof truss members, cables et
Laterally unrestrained steel beams are beams in which the compression flange do not have sufficient restraint and as a result susceptible to lateral-torsional buckling, a failure mechanism of steel beams due to buckling
Understanding the design of steel beams depend to a large extent on whether the compression flange is laterally restrained or not. This is because when a steel beam is subjected to flexure, there is a tendency for it to buckle along its length.
