(OIL AND NATURAL GAS CORPORATION) is a Government of Indian company,presently engaged at various locations in India. They need a suitable compressor sheltertosupport heavy pipe lines and equipment for production of hydrogen.We have been assigned to design for them “Steel Compressor Shelter? at the Location in IndiaThe Client needs to install hydrogen plant for which it was calculated to design ofcompressor shelter of size11m x 8m x 9.7m height.Ground level is considered at 100.00 m abovesea level.Structure Description:Compressor shelter SG0101 is11 m long in N-S direction and 8 m wide in E-W direction.Height ofshelter is9.7 m above High Point of Paving (HPP).? Moment connection is provided along N-S direction and shear connection in E-WdirectionSTRUCTURAL PARTS:? Column: The proposed shelter structure would be supported with 6 main steel columns fabricatedout of ISMB500 I Sections .? Beams and Bracing: The Proposed Shelter Structure would have beams fabricated out of section ISMB500 andbracings of 2 ISA200 x 200 x 16.? Roofing and Sides: The Roofing will rest on purlin fabricatedout of channel „U180? for resting „corrugated ACsheets?.4 Design Methodology:Design of Compressor shelteris based on Such IndianCodes like, IS 800: 2007– General Construction in Steel: Code of PracticeIS 875:1987 – Code of Practice for Design Loads other than EarthquakeIS 1893:2005 – Criteria for Earthquake Resistant Design of StructuresIS 875 (Part1 & 3):1987 – Code of Practice for Design Loads for Buildings& StructuresInput:?

Working with different discipline gives challenge to design structure with ourown philosophy. Sometimes structural arrangement needs to be changed based on therequirement of other disciplines.Once the basic structure arrangement getsfinal then have to start 3D modelling in CADsoftware.3D modelling is essential and gets benefited while more than one discipline is working onsame platform. So it gives much clear understanding. Smart Plant 3D is used for modellingAfter modelling gets done, there are two activities which are to be done parallel,One is analysis and design and second is drawing preparation.Analysis and Design: The calculation for loads has been devised from „STAAD pro? analysissoftware. Size of various sections has been finalized from this software. This also provideddata for various loads and moments at joints.Drawing is prepared by drafting software like Micro station, AutoCAD, etc.Preparation of as built documentation means after finalization of section size and drawing,required documentation should be done and drawing is forwarded to fabrication unit.9 Design1) DESIGN CRITERIA? Material : Structural Steel? Structural Steel of Grade 415 in accordance with IS :2062 - 2006? Mini Ultimate Tensile Strength Fu = 410 MPa? Allowable Yield Strength Fy = 250 MPa? All calculations related to strength and serviceability of the superstructure isperformedas three dimensional mathematical model using STAAD.Pro V8i.? Piping/equipment loading on each floor considered as per load marked on drawings.2)DESIGN LOADS2.1 Dead Load (DL)? Structural weight is calculated by the self-weight command of STAAD.? Dead load comprises of the weight of all permanent construction including wallcladding, roofs cladding etc.? Unless otherwise noted , thefollowing unit weights are adopted: Structural steel:78.50kN/m³ 1.6 mm thick galvanised steel sheet: 0.131 kN/m2( Page - 10 - IS 875 - Part 1 )2.2 Live Load (LL)? Live loads are applied, in general, as per IS: 875 - Part - II. 2.4 Wind LoadsWind loads have been calculated as per IS: 875 (Part-3)-1987.Basic wind speed is 44m/s.As per IS:875 (part-3), definition of basic wind speed shall be peak gust velocityaveraged over 3 second time interval at 10 m height above mean ground level with 50years mean return period.2.5 SeismicSeismic analysis is done using the provisions of IS: 1893-2002(Part-1) & IS1893 -2005(Part -4). In order to calculate lumped masses at various beam-column intersectionpoints, a separate mathematical model file is created with supports defined at suchlocations. The loading for this file includes dead loads, operating loads and 25% of liveload (Table-8 IS: 1893:2002 (Part-1)). The vertical support reactions are thentransferred to the main mathematical model file as a lumped mass. STAAD Pro in builtseismic load generator is used for further seismic analysis.10 2.6 Vibration Load / Dynamic Load (VL)? Not Applicable2.7 Handling Device Loads (HL)?

V8i. 3D spacestructureup to bottom of Base plate with framed beams, bracings and columns have beenprepared forSTAAD space frame analysis.The general system of the computer model for foundation is with global axes system:X = Horizontal axis in computer model along East - West direction.Y = Vertical axis in computer model (positive upward direction)Z = Horizontal axis in computer model along North - South direction.4.1 Support ConditionAll steel columns bases at top of concrete Pedestals (EL +0.300) are considered as FixedbutSupport, Pin in X direction and Fixed in Y and Z.4.2 Computer Model? Minor Members like beams for walkway, Joist for supporting floors, cantilever beamsfor pipe supports etc, are not modelled in STAAD. However, the loads of thesemembers are considered and applied at appropriate locations? Various parameters used for member design are mentioned in the following table.? Deflection check for the columns has been provided in the following pages.? Deflection check for beams has been carried out in STAAD Pro v8i.? Output results of the deflection check for beams (shown in following tables) are onlyfor those beams which govern in deflection.? Permissible value of deflection for beams is considered as L/250? Permissible value of horizontal deflection is considered as H/20012 "
