INFLUENCE OF EFFECTIVE LENGTHS ON RELIABILITYOF HOT-ROLLED STEEL COLUMNS

📄 Project Abstract

In response to increasingly stringent architectural and cost requirement in modern buildings, the use of slender building elements, has become more common in steel sections, thus making it necessary to provide a comprehensive evaluation of the behaviour of these columns in compression (Khalil et.al, 2001). The aim of structural design is first to provide, with due regards to economy, a structure capable of fulfilling it's intended functions and sustaining the design loads for it's intending life time (BS 5950, 1990). The requirement that a structure performs effectively without failure during its design life is fundamental. Failure is implied in the sense of exceeding a certain limit state corresponding, for example, to a measure of un-serviceability or instability (Abejide, 2007; Ellingwood, 1978; Melchers 1974). When making calculations to determine the sizes of structural members to resist tension, compression, shear, bending, or other structural loads, the engineer refers to standa...
