| dc.description.abstract | Fatigue is an initiation and circulation of microscopic cracks into macro cracks by cyclic loading of stress. The failure induced in a structural member due to fatigue is called fatigue failure. Such type of failure is common in steel structures like bridges, gantry girders, crane girders, offshore structures, etc., which are prone to moving and repetitive loading. It is also claimed that nearly 80% of all structural failures are associated with fatigue. This study focuses on comparison of fatigue design method for steel structures as per Indian standard (IS800), Australian standard (AS4100), Eurocode (EN1993-1-9) and American standard (AISC360). The study includes fatigue design of gantry girder with 25T and 50T capacity, with span varying from 6m to 10m, using stress cycles as 400000 and 560000. The parameters used here reflect the data of the local survey done in Industrial estates of Ahmedabad. The normal design of gantry girder is done as per IS800. The fatigue design of the girder is compared as per different standards. It is concluded that Indian standard is conservative for flexural stress as well as shear stress under fatigue assessment amongst all considered standards. Further, around 10% escalation in the overall section of the gantry girder was observed when the number of stress cycle was increased from 400000 to 560000, irrespective of spans and capacities. | |
