The requirement of steel structures having larger To introduce the students to limit state design of structural steel members subjected to compressive, tensile and bending loads, including connections. It was found that the use of hybrid plate girders is cost-effective compared to ordinary plate girders. Center to center distance of gantry girder = 12m Wheel spacing = 3m Edge distance = 1m Weight of crane girder = 40 kN Weight of trolley car = 10 kN Design by allowable stress method as per IS: 800 - 1984 To find wheel load (refer fig.1): 3 4 Column or Bracket Support • Do not use framed or clip angle type connections. 6.1. (IS:800-2007, Page-59) Difference between elastic & plastic section modulus. Intermediate vertical stiffeners in a plate girder need be provided if the depth of web exceeds a) 501 b) 851 c) 200 t d) 2501 where t is thickness of web Ans: b. 10.13 Procedure of Design of Plate Girder 321 10.14 Summary 341 11. Fig. After proper calculations, the results for static as well as dynamic analysis are obtained. 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). 4���������W��S�� o�r ��eg��H�(� ;� Various types of stiffeners.
