Detailing for Economy  \n8.1 Detailing on Design  \nEngineer’s Drawings  \nIt is in the design office that the potential economy of any steel structure is effectively determined. Judicious decisions on details at this stage can provide for simple, economic methods to be used at the fabrication stage.  \nThe designer is faced with the problem that a different fabrication and erection technique could be favoured by each individual fabricator likely to tender for the project. It is a good idea at the outset for the designer to have some preliminary discussions with likely fabricators and steel detailers to check on latest techniques prevailing in the industry. From these discussions the design and detailing approach for the structure can be carried outwith factors influencing economics firmly in mind.  \nIn the normal course of events a steel structure passes through several separate stages involving design, detailing, fabrication and erection. With this in mind, it is important for designers to remember that a minimum of design detailing by them will assist towards economy, since the steel detailer is then left free to make the most efficient use of the particular fabricator’s capabilities (Ref. 2.12) . The need for this flexibility is often overlooked by designers in their anxiety to specify their requirements.  \nSuch things as a fabricator’s ability to fabricate large subassemblies in the shop and subsequently transport to site and erect them will obviously have a bearing on the design of connection types and therefore on the economy of the overall project. In this regard it must be stressed that a maximum of work done in the workshop will almost always produce better quality and more economical structures.  \nIn the presentation of working drawings therefore, the basic key is ‘communication’ which normally takes place through a chain as illustrated in Figure 8.1.  \nCLIENT  \nARCHITECT  \nBUILDER:  \nCONSULTING SERVICE ENGINEERS  \nCONSULTING STRUCTURAL ENGINEERS  \nSTEEL DETAILERS  \nERECTOR STEEL FABRICATION PROTECTION  \nOF STEEL  \nFIGURE 8.1: Chain of communication  \nThe processes involved in the design can be summarised in the following sequence:  \n• Initial communication.  \n• Structural concept including consideration of connection types.  \n• Integrated design.  \n• Connection detailing.  \n• Framing plans.  \nThe Engineer’s structural framing plans must contain all the necessary information to enable the fabricator to have shop drawings prepared for the individual members, as well as the marking plans to identify each member for the erection phase.  \nGuidance for designers is provided by the Australian Institute of Steel Detailers Contract Documents Completion Checklists, Ref. 8.1.  \nThe following discussion is intended to highlight aspects of the detailing of both members and connections to achieve economy in the overall fabrication and erection of structural elements.  \nAs an additional consideration the use of ASI: Connections Design Guides – First Edition 2007 (Ref. 1.) will enable designers to specify standardised connections directly from the publication without detailing, and if necessary permit alternatives to be offered by the fabricator with the confidence of assured design capacity and behaviour.  \n8.2 Beams  \n8.2.1 GENERAL  \nThe simplest and therefore the most economic beams in structures will be of rolled universal sections. Wherever possible, it will almost always prove more economic in one-off types of steel structures to use a universal section or welded beam section as a beam, even if a heavier solution results. The alternative fabrication of a threeplate girder introduces plate preparation, assembly and welding, the costs of which will generally exceed the cost of additional material in the rolled universal section or standard WB section, unless a vast amount of repetition is required.  \n8.2.2 PLATED SECTIONS  \nWhere headroom limitations apply (distance from ceilingsoffit to floor level), it may be necessary to con","cbCaicQRnIvEPUlY","https://ap.wps.com/l/cbCaicQRnIvEPUlY","pdf",281193,"English","# 8.
