Simulation Analysis in Lateral Torsional Buckling of Channel Section by Using Ansys Software
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2020, Vol 4, Issue 2
Abstract
Design rules for eccentrically loaded beams with open channel cross sections are not available in Indian code IS 800 2000 general construction in steel code of practice third revision . In this study Indian standard medium weight parallel flange ISMCP 175, ISMCP 200, ISMCP 3000 channel beams are used different span length to section height ratio of the beams is taken. The type of loading and the uniformly distributed load application are limited through the web of the channels. General solutions like Elastic critical moment, Slenderness, Reduction factors and the Ultimate loads are determined by using formula given in ANNEX E CL.8.2.2.1,IS 800 2007 for mono symmetric beams and compared with NEW DESIGN RULE snijder and with Finite Element FE simulations on the basis of a parameteric study using ANSYS software 14.0. It is was noticed that mono symmetric formula in code is giving elastic critical moment results upto 0.3 difference with ANSYS result for slender beams but showing larger difference for stocky beams. As the size of beam is increasing with constant cross section it is resulting in reduction in design capacity. The design curve for channel beam proposed by snijder seems to be a good choice , taking torsional effect into account, but it dosent claim to be correct for beams with a ratio L h 15. The results obtained from the IS code formula is matching with ANSYS results for beams having length to depth ratio between range 20 to 40.
