SPADE *** Structural Parts And Details Ensemble ***

SPADE is a computer program for producing drawings for a variety of components. SPADE is not just an electronic drawing board, it is an 'expert detailer' which does the drawing for you, producing to-scale details.

The details produced by SPADE are text files, written in HPGL (Hewlett-Packard Graphics Language) and may be:

  • sent directly to printer (thus the SPADE detail may be printed on any printer which is supported by Windows)
  • edited by the supplied program called TAPE (Translator And Plot Editor) and then printed
  • converted to .DXF and read and edited by your own CAD system.

SPADE is an 'expert system' which knows about detailing and builds the detail using the knowledge contained within the SPADE database. The engineer merely has to guide SPADE by giving answers to the various questions which SPADE asks. This does not mean that SPADE is restricted to the knowledge contained within itself, for SPADE incorporates an easy to use drawing program called TAPE which allows the user to add to or amend the SPADE detail to incorporate the engineer's own expert knowledge.

Thus SPADE offers the best of both worlds:

  • the skills of an expert detailer
  • the means to add the engineer's expert knowledge and thereby produce a detail tailored to the job.

Historical Background.

The LUCID system is limited to reinforced concrete detailing; SPADE has been developed to extend the principles of LUCID to steelwork, masonry and timber detailing. During the development of SPADE the following publications were consulted:

  • Manual on connections for beam and column construction to BS449 by JW Pask; published BCSA.
  • Manual on connections - volume 1 - joints in simple construction to BS5950 by JW Pask; published BCSA.
  • Metric practice for structural steelwork; published BCSA.
  • Plastic Design of Low-Rise Frames by MR Horne and LJ Morris; published by Constrado (now SCI).
  • Steel Designers' Manual - Fifth Edition 1992; published by BSP.
  • Steelwork Design Guide to BS5950; published by SCI.
  • Steel Detailers' Manual by Alan Hayward and Frank Weare; published by by BSP.
  • Structural Steelwork Design to BS5950 by LJ Morris and DR Plum; published by Longman Scientific & Technical.
  • Verification of design methods for finplate connections by DB Moore and GW Owens; published by The Structural Engineer - Feb 1992.
  • Foundations for low-rise buildings by MJ Tomlinson, R Driscoll ,& JB Burland; published by The Structural Engineer June 1978.
  • Raft foundations in mining areas, correspondence by J O'Rourke; published The Structural Engineer October 1983.
  • Structural design of Masonry by Andrew Orton; published by Longman.

The development of the SPADE program was carried out by Doug Brown, the development of the SPADE proforma details by Robert Coombes and Gary Jackson, the utility TAPE (for editing the SPADE details and translating them into DXF format) by Clive Emberey.
