Steel columns in simple construction are the most popular type of columns encountered in multi-storey steel buildings in practice
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.
Steel sections must be classified before a design can be carried out. This is because steel sections are highly subjected to large compressive stresses and could possibly fail through buckling if the plates comprising the steel section are very slender
Five years into the night of 18 January 1978, when the Civic Center had been exposed to its heaviest snow load since construction – heavy, but still only half of the design load. At 4:19 that morning, with the arena empty, the 1270t space frame collapsed in its entirety (see post cover mage). What was most disturbing, though, was that just six hours ago, more than 5,000 people were sitting below, watching a basketball game.
Fatigue is a type of failure that occurs when a material fails at loads below the specified yield strength. It usually occurs from stress from cyclical loading over a period of time
Extreme loading situations are often known as ‘accidental loads’ because they occur under circumstances that are typically due to events that are inherently unlikely to occur.
