Compos 8.1 Build 1: New Features

• "History" option has been added. The "History" is a list of history records, each made up of a date, time, user name and an optional note, to serve as a history of changes to the model.
• The new Oasys Technical FAQ can be accessed via 'Help | Technical FAQ'.
• A new version checking system has been implemented, giving more explicit identification of the version being run and options for periodic checking. See 'Help | About Compos'.
• 2009 amendment (draft) to BS 5950 Part 3.1 has been implemented as a new design code option.
• Requirement for composite beam natural frequency is taken into account in member design, if a member does not meet the frequency requirement, the steel beam section will be increased until the member meets this requirement.

Compos 8.1 Build 1: Fixes

• The dimensions of metal deckings SMD TR60 and TR80 are slightly wrong, e.g. the correct dimensions for TR60 are 144 mm and 133 mm, but 140 mm and 140 mm were used, the correct dimensions for TR80 are 114 and 104 mm, but 140 mm and 120 mm were used.
  [NCR3480] (Fixed 6 April 2009) (fixed in metal decking database)
• The thickness of metal decking ComFlor 80 (0.9) is wrongly used for metal decking ComFlor 80 (1.0) and vice versa.
  [NCR 4373] (Fixed 16 December 2009)
• Some of the Corus metal deckings [ComFlor 70 and ComFlor 80 (1.0] used in Compos are out of date.
  [NCR 4385] (Fixed 18 December 2009)

Compos 8.0 Build 3: New Features

• Output view has been improved and it is now more compact and if printed it will take less pages.
• Stress check based on Clause 2.4.3 of BS5950 Part 3.1 has been added as analysis and design criteria.
• Floor footfall analysis results are available from text output, they were available only on graphic before.
• Steel beam top flange width check based on Clause 5.3.1 of SCI 300 has been added, so if top flange width is less than 133 mm, a warning will be given.

Compos 8.0 Build 3: Fixes

• Construction stage constraints from secondary members are ignored even though the check box has been checked to indicate they should be considered.
  [NCR1419] (Fixed 1 April 2007) (Released on 4 May 2007 in Compos.exe 8.0.12.1)
• The shear force of right end notch is always zero.
  [NCR1420] (Fixed 11 April 2007) (Released on 4 May 2007 in Compos.exe 8.0.12.1)
• The cover of transverse reinforcement given by Compos is 10mm less than the correct value if the trasverse reinforcement is chosen to be designed by the program.
  [NCR1421] (Fixed 21 April 2007) (Released on 4 May 2007 in Compos.exe 8.0.12.1)
• The design strength rather than the characteristic strength of reinforcement is used when calculating the transverse shear capacity of reinforcement using the equation in Clause 5.6.3 of BS5950 Part 3.1. The characteristic strength should be used for this equation, therefore, the transverse shear capacity of reinforcement is 15% underestimated.
  [NCR1422] (Fixed 1 May 2007) (Released on 4 May 2007 in Compos.exe 8.0.12.1)
• The default decking material grade cannot be changed, so the first grade of the two available decking grades is always used.
  [NCR1484] (Fixed 15 May 2007) (Released on 15 May 2007 in Compos.exe 8.0.12.2)
• When web opeonings are subjected to very high shear, the Vierendeel moments are underestimated
  [NCR2036] (Fixed 14 September 2007) (Released on 21 September 2007 in Compos.exe 8.0.12.3)
• The lambda for lateral torsional buckling analysis of steel beam is wrong for construction stage check
  [NCR2602] (Fixed 17 March 2008) (Released on 17 March 2008 in Compos.exe 8.0.12.6)
• The position of the first steel section is sometimes wrongly altered after going through the section wizard.
  [NCR 2981] (Fixed 31 July 2008)(Released on 12 August 2008 in Compos.exe 8.0.12.7)
• The axial load is presented on the load table, but it is not used in Compos analysis.
  [NCR 2986] (Fixed 1 August 2008) (Released on 12 August 2008 in Compos.exe 8.0.12.7)
• 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)
• Even though the steel beam top flange width is larger than 133 mm, the warning message of top flange width less than 133 mm is always given.
  [NCR3028] (Fixed 21 August 2008) (Released on 21 October 2008 in Compos.exe 8.0.12.10)

Compos 8.0 Build 2: Fixes

• If a member has been used as a member load and its name has been changed, the member load table is not updated accordingly, so the member load has been ignored in the analysis.
  [NCR12] (Fixed 31 October 2006) (Patch released 28 November 2006 in Compos.exe 8.0.10.0)
• If a composite beam has a solid slab and the transverse shear capacity is controlled by shear surface b-b, the transverse shear capacity has been underestimated if the member is re-analysed.
  [NCR14] (Fixed 11 November 2006) (Patch released 28 November 2006 in Compos.exe 8.0.10.0)
• 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)
• The restraints from secondary beam is always ignored even "Take secondary beam as intermediate restraint" box is checked on "Restraints in Construction Stage" page of the member property wizard.
  [NCR16] (Fixed 11 January 2007) (Patch released 11 January 2007 in Compos.exe 8.0.11.0)
• The shear force for the notch at right hand side of the beam is sometimes wrongly taken as zero if the meber has uniform steel beam section, but it has been defined at both left and right hand sides of the member.
  [NCR17] (Fixed 11 January 2007) (Patch released 11 January 2007 in Compos.exe 8.0.11.0)

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 8.0 Build 1: Fixes

• The background colour of the saved JPEG file is always black.
  [NCR3] (Fixed 28 October 2005) (Patch released 28 October 2005 in Compos.exe 8.0.1.2)
• When opening a file with user defined construction stage restraints, the intermediate restraints have been deleted.<
  [NCR4] (Fixed 28 October 2005) (Patch released 28 October 2005 in Compos.exe 8.0.1.2)
• When copying member, the steel beam section is not copied, so the two members will use the same steel beam section.
  [NCR5] (Fixed 3 November 2005) (Patch released 3 November 2005 in Compos.exe 8.0.1.4)
• When slab transverse shear capacity is controlled by b-b type failure, the reinforcement transverse shear capacity is wrong even though the reinforcement area is correct.
  [NCR6] (Fixed 19 December 2005) (Patch released 21 December 2005 in Compos.exe 8.0.1.5)
• If the member property wizard is open while creating a new member, Compos crashes after the new member has been added to the data manager.
  [NCR9] (Fixed 17 January 2006) (Patch released 18 January 2006 in Compos.exe 8.0.2.0)
• If the last defined slab section is not at the end of the composite beam, the calculated effective slab widths are wrong adjacent to the location of the last defined slab section.
  [NCR10] (Fixed 17 February 2006) (Patch released 20 February 2006 in Compos.exe 8.0.5.0)
• If the final dead loads are smaller than the construction stage dead loads, the calculated deflections are wrong.
  [NCR11] (Fixed 28 February 2006) (Patch released 28 February 2006 in Compos.exe 8.0.8.0)

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
