Studying Stress Distribution under Steel Base Plates Using IPE Profiles

Iranian Steel Design Code is based on American Steel Design Code. In American code, effective stress distribution zone under base plates is considered as rectangular zone and this stressdistribution corresponds with IPB profiles, while in Iran, IPE profiles are used commonly. Answer to this question that whether stress distribution associated with IPB profiles is same as using IPE profiles or not is our research’s basis. Main goals of this study include: 1) manner ofstress distribution under steel base plates supporting IPE and 2IPE profiles. 2) Effect of steel base plate thickness on stress distribution under steel base plates. 3) Effect of dimension of steel base plates on stress distribution in base plates. 4) Effect of cover plates thickness on magnitudeand manner of stress distribution in steel base plates. In this study, initially theories proposed by researchers in relation to stress distribution understeel base plates were studied. Also, ANSYS Software has been used due to its nonlinear analysis capability. In present investigation, 9 models containing IPE columns with base plates in various thickness and dimensions and 27 models containing coadunate 2IPE columns accomplished with coverplates erected on base plates in various thickness and dimensions were selected, then the models were analyzed by ANSYS Software.
