  • EC4 design: Compos is limiting the effective width of slab to 0.8*times the available width when the decking is running parallel to the beam. This is in accordance with BS5950-3 clause 4.6 (b) and application of this rule to EN 1994-1-1:2004 design is incorrect.
    [NCR 7322] (fixed on 14th Aug, 2012) (Released in compos.exe 8.3.0.5)

  • When decking is perpendicular to steel beam, the longitudinal stud edge distance is not checked properly, a physical fitness need to be checked, so Compos will not put too many studs in logitudinal direction that can be fit.
    [NCR3020] (Fixed 19 August 2008) (Released on 21 October 2008 in Compos.exe 8.0.12.10)

  • If the slab width is variable, the checking of slab transverse shear capacity may be missed out for the second as well as the following slab sections defined in the concrete slab table.
    [NCR15] (Fixed 28 November 2006) (Patch released 28 November 2006 in Compos.exe 8.0.10.0)

    3D graphic view

    3D graphic view shows the image of the composite beam in 3D space. The composite beam can be rotated, panned, enlarged or reduced. Each of the components of the composite beam can be switch on and off individually on the graphic view to enable each of component to be examined individually.

    Better 2D graphic view

    2D views for elevation, cross section, web opening and loading. Detailed dimensions are given on the graphic view. They can be printed individually or embedded on the results summary output

    Graphic view of applied loads

    Applied loads can be viewed on 2D graphic - load diagram. Schematic view of the loads are also available on 3D graphic.

    Area loads

    Uniformly distributed area load. The area subjected to this load is the available width (may be variable) along the full length of the concrete

    Member loads

    The organisation of analysis case and analysis task definition data has been rationalised and access to this data has been improved. This is to enable the editing of the full content of analysis definition data. In achieving this Member loads have been given greater prominence than in previous versions of GSA.

    Design option to use minimum number of shear studs

    Option for using minimum number of shear studs that also satisfies load capacity as well as other code requirements.

    Design to selected section types

    In design, Compos will find the steel beam section to meet the minimum weight or minimum depth criterion that also satisfies the load capacity requirement. In previois version, only UB sections are used in the design, now the section types to be used in design can be defined

    No stud zones

    No stud zones on each or both ends of the composite beam can be specified. This is useul when damping layer is required between concrete slab and steel beam to reduce the response of the composite floor.

    Variable concrete slab section

    Both the width and depth of the concrete slab can be changed or tapered along the span.

    Metal decking angle

    There is no limitation on the direction of metal decking. It can be parallel or perpendicular to the beam or in any angle with the beam.

    Member property to other members

    The member properties in the current page of the Member Property wizard can be applied to other members. This is usefull for making certain properties the same for a group of members.

    Program produced shear stud layout

    If automatic stud spacing is selected, Compos will give the actual layout of the shear studs.

    Text data file

    Tab separated and comma separated (CSV) text data (ASCII) files are supported by Compos 8.0.

    User defined units

    User defined units can be used for input and output.

    More metal decking types

    Metal deckings from catalogues of Richard Lees, Kingspan, SMD and Corus PMF are supported by Compos 8.0.

    COM user interface

    COM (Component Object Module) user interface enables users to run Compos through the exported functions of Compos in their program, e.g. C++ program or VBA etc. This will enable Compos to be run non-interactively or in a batch operation.

    Foot-fall induced floor vibration

    Foot-fall induced floor response analysis is a serviceability limit state analysis to evaluate the response of the composite floor subjects to human walking actions.

    Version Checking

    So as to help users ensure that they are running the latest software a new version checking system has been implemented. This compares each Compos executable file installed locally with the set that Oasys identifies as being the ‘current versions’. (The comparison is carried out locally; no data is transmitted to Oasys.) Executables for which updates are available are highlighted. Updates may then be downloaded from the Compos Downloads page.

Compos Outstanding Bugs/problems

  • When printing summary results with graphics, sometimes one or two graphics are missing in the print output. This may have something to do with the printer driver and the problem is not consistent and the real couse has not been found.
    [NCR13] Reported on 30 May 2006
  • When opening a Compos file on oriental operating system, Compos sometimes crashes due to the temperature unit stored in the registry is a oriental character which is not recognised by Compos and causes the crashes. Editing the registry to remove this character can help to prevent the crashes
    [NCR1283] Reported on 16 March 2007
