Design by allowable stress method as per IS 800 1984 June 5th, 2019 - Capacity of crane 50 kN Longitudinal spacing of column 6m 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 Factored Logitudinal Force (KN) = 12.15 The gantry girder carries the two wheel loads and its own weight. A gantry girder is the piece of a crane that contains the equipment allowing the crane to roll over during its operation. A gantry girder is supported by columns, with little or no support between the columns to avert the twisting and bending of the girder metal. 6.1. CE 591 – Advanced Structural Steel Design. The hook-chain system is supported on a pulley. Corresponding to the wheel loads the appropriate lateral forces are determined. Ratio = 1 ::: Refer Section Strength : Clause 9.3.1.2 Project Management Templates. Share to Twitter Share to Facebook Share to Pinterest. The data needed for gantry girder design are, Capacity of the crane, Crane span, Weight of the crane, End carriage wheel centres (Wheel base), Minimum hook approach, and Maximum static wheel load. determined, AASHTO type 4 girder was chosen as the girder used in this design. 11.10), With this condition, Maximum bending moment = W/8l (2l – a)2. This book is aimed at training the students in using IS: 800 2007 for designing steel structures by limit state method. Determination of the Maximum Wheel Load: For the gantry girder under consideration the crab on the crane should be at the closest permissible distance from the gantry girder in order to produce the most critical shear force and bending moment. This spreadsheet can be used for learning as well as designing purpose. The crab housing the winches is supported over the crane. The shear force and bending moment due to impact effect are calculated. 6 Gantry Girder 6.1 Introduction Usually, most of the industrial buildings have built-in overhead cranes for handling heavy equipment or goods. Factored Vertical BM in Gatry Girder (KN-M) = 686.1 crane gantry girder design default example tumcivil com. RCC DESIGN EXCEL SHEET. Gantry girders supported on columns, carry the moving cranes. The rails over the gantry girder are firmly fixed to the girder by bolted clamps or hook at a spacing of 0.50 m to 1 m to prevent the rail from lateral dislocation due to lateral forces. This spreadsheet can be used for learning as well as designing purpose. d/tw = 32.47 3. CRANE GANTRY GIRDER DESIGN DEFAULT EXAMPLE TUMCIVIL COM. Zzb Of Compound Section (cm3) Bottom = 3311.55 CHAPTER 9 STEEL PLATE GIRDERS Caltrans. It is not usual to weld the rails to the gantry girder since welding makes it difficult for any readjustment of alignment of rails. Copyright 10. Ky = 1 M_ZZ of Section in KN-M = 703.19 Design by allowable stress method as per IS 800 1984. -------------------------- n = 0 IZZ Of Compound Section (cm4) = 120611.82 The following allowances are made to cover all forces caused by vibration, shock from slipping of slings, kinetic action of acceleration and retardation and impact of wheel loads. As the name suggests this Design Plate Girder Spreadsheet can design plate girders. Thickness of FLANGE PLATES (mm) = 0 The retardation may be assumed to be uniform and can be determined from the equation-. Structural Steel Design Plate Girders. 6 Gantry Girder 6.1 Introduction. A section consisting of an I-section with a channel section attached to the top flange is proposed. Lambda_Z = 30.68 [gravityform id="1" title="false" description="false" ajax="true"]. The design loads on the gantry girder depends upon the minimum or the closest approach distance of the hook from the axis of the gantry girder. Minimum thickness of web in a plate girder, when the plate is accessible and also exposed to weather, is a) 5 mm b) 6 mm c) 8 mm d) 10 mm Ans: b. Design Of Gantry Girder As Per IS 800 2007.
