ADC 8.4 Build 12: New Features

ADC 8.4 Build 12: New Feature — Column

  • A new Perimeter Reinforcement option is available for column design. This allows reinforcement to be placed in one or more layers around the perimeter of a section, based on spacing criteria. At present this is available for rectangular, tapered or perimeter sections. This is primarily to allow the design of large sections beyond the scope of the existing templates. Circular section should continue to use the existing circular template.

ADC 8.4 Build 12 : Fixes

ADC 8.4 Build 12: Fixes — Rib, Beam & Column

  • Rib Design: Basic span/depth ratio is not correct in EC2 rib design as steel required is taken at the free end rather than the non-free end in the case of a cantilever.
    [NCR10795] (Fixed 04 April 2016) (Released in AdRib 8.4.0.12)
  • Beam Design: In EC2 beam design, the distribution of link reinforcement along the member is not correct when there is a heavy point load near a support.
    [NCR10520] (Fixed 04 April 2016) (Released in AdBeam 8.4.0.12)
  • Column Design: When N*(applied load) > Nc(buckling load) then a buckling failure warning is reported in the output while the design is carried out by limiting the moment magnification factor to 11.
    [NCR10796] (Fixed 04 April 2016) (Released in AdCol 8.4.0.12)
  • Column Design: For EC2 ADC was not doing a maximum bar spacing check. The maximum bar spacing is now set to 150mm, based on a crack width of 0.3mm, and a steel stress of 280MPa as per Table 7.3N.
    [NCR10797] (Fixed 04 April 2016) (Released in AdCol 8.4.0.12)
  • Column Design: ADC is not allowing the modification of bar limits, requesting a positive value because continuity reinforcement was getting checked for the column, which was not required.
    [NCR10798] (Fixed 04 April 2016) (Released in ADC 8.4.0.12)

ADC 8.0 Build 6: Fixes — General

  • Selecting the Wizard option via the context menu in some tables fails to open the Wizard.
    [NCR23] (Fixed 19 April 2005; released in Adc.exe 8.0.6.0)
  • Output is printed in condensed form only.
    [NCR24] (Fixed 17 May 2005; released in Adc.exe 8.0.6.0)
  • ADC 8.0 offers the design code option of "Hong Kong Code of Practice 2004". In fact what is selected by this option is what was previously labelled "BS8110 (Hong Kong)" and is "Hong Code Code of Practice 1987".
    [NCR39] (Fixed 6 September 2005)
  • ADC may crash upon opening files by double-clicking the filename via 'File | Open' or the 'Recent Files' list if the file has a long filename or is held in a deep folder structure. This bug is avoided if the file is opened instead by selecting it via a single-click, and then clicking the 'Open' button.
    [NCR41] (Fixed 3 November 2005; released in Adc.exe 8.0.6.0)
  • ADC's 'About Dialog' fails to list all of the program's components.
    [NCR42] (Fixed 4 November 2005; released in Adc.exe 8.0.6.0)
  • Formatting scientific values to n significant figures may produce errors (e.g. 8.99999 to 4 sig figs gives 8.100 rather than 9.000).
    [NCR45] (Fixed 10 November 2005; released in OaUtil.dll 3.0.15.1)
  • AdCol files, containing large numbers of sections, may take a long time to save after performing section validation. This is particularly evident when saving over a network. (Part 1 of 2 - see NCR 48 for Part 2).
    [NCR47] (Fixed 28 November 2005; released in AdFile.dll 8.0.4.1)

ADC 8.0 Build 6: Fixes — AdBeam

  • AdBeam crashes when a user load factor is deleted from the input data.
    [NCR17] (Fixed 4 April 2005; released in AdcData.dll 8.0.5)
  • AdBeam may fail to present the full list of warnings/errors upon attempting a design, though the design results are unavailable - indicating that design has not been performed.
    [NCR19] (Fixed 8 April 2005; released in AdBeam.dll 8.0.5.0)
  • The setting to include beam self weight is saved when set in the General Specification dialog, but not when set in the Load Details page of the New Model Wizard.
    [NCR25] (Fixed 12 May 2005; released in Adc.exe 8.0.5.0 and AdcData.dll 8.0.6.0)
  • When designing a solid slab AdBeam invites the user to enter a side cover unnecessarily.
    [NCR18] (Fixed 17 May 2005; released in Adc.exe 8.0.6.0)
  • ADC does not check correctly whether the maximum shear in a beam exceeds the BS8110 limit of 0.8 x √fcu or 5N/mm2. It checks the shear at a distance 'd' from supports rather that at the supports.
    [NCR26] (Fixed 6 May 2005; released in AdBeam.dll 8.0.6.0)
  • The online help incorrectly suggests that the user has control over whether 'd' should be used when determining the position of the shear check.
    [NCR27] (Fixed 31 May 2005)
  • Designs that contained bunched bars in ADC 7.2 may fail to be achieved in ADC 8.0. The warning 'Error in beam design' may be shown.
    [NCR29] (Fixed 7 June 2005; released in AdBeam.dll 8.0.5.0)
  • AdBeam may fail to analyse a model, or may even crash, due to unitialised materials. This problem occurs when the Section Wizard is used in the 'span and support details' page of the New Model Wizard to enter upper or lower column sections. To avoid the problem either (a) enter the section descriptions directly without clicking the 'Section' button (but instead by typing e.g. 'STD R 300 300') or (b) upon completion of the New Model Wizard, initialise the materials by opening the materials dialog from the program's gateway, and clicking 'OK'.
    [NCR31] (Fixed 24 June 2005; released in Adc.exe 8.0.5.0)
  • The 'Notional Loads' table view shows a column 'Direction'. This is not necessary, since the sign of the load indicates its direction.
    [NCR34] (Fixed 24 June 2005; released in Adc.exe 8.0.6.0)
  • It should be possible to click the 'standard' or 'user-defined' title in the gateway and have the already opened table view change the active tab. This does is not functioning correctly for the 'Load Factors' and 'Load Combinations' tables.
    [NCR35] (Fixed 24 June 2005; released in Adc.exe 8.0.6.0)
  • AdBeam may give misleading solutions for a beam that is unreinforceable e.g. it may suggest a solution of T16 bars when the maximum bar size is limited to 50 mm, but appear to fail to find the same solution when the maximum bar size is 80 mm. AdBeam has in fact failed to recognise that the section was unreinforceable in both cases.
    [NCR37] (Fixed 14 July 2005; released in AdBeam.dll 8.0.6.0)
  • AdBeam may recommend solutions whose longitudinal reinforcement in tension is spaced at more than the maximum allowed by the design code or the reinforcement detailing manual.
    [NCR38] (Fixed 8 August 2005; released in AdBeam.dll 8.0.6.0)
  • The Loads table in the Output View shows the values of the loads but not their positions. The values are mis-aligned with their column headers.
    [NCR40] (Fixed 13 September 2005; released in Adc.exe 8.0.6.0)
  • The Wizard button should be disabled for the Redistribution table if redistribution results are available, and for the Covers table if design results are available.
    [NCR43] (Fixed 9 November 2005)
  • AdBeam may crash when designing a flat slab or ribbed slab after installing the patch version 8.0.6.0 of AdBeam.dll.
    [NCR44] (Fixed 10 November 2005; released in AdRib.dll 8.0.5.0 and AdSlab.dll 8.0.5.0)

ADC 8.0 Build 6: Fixes — AdCol

  • If the required cover is not a multiple of 5 mm, then AdCol should round it up to the nearest 5 mm. However, in some circumstances AdCol may add 5 mm to the cover unnecessarily if the minimum cover is 40 mm or more.
    [NCR20] (Fixed 17 May 2005; released in AdBeam.dll 8.0.5.1)
  • If the user switches from biaxial bending to uniaxial bending in AdCol, then Mzz moments should be disabled and ignored. This adjustment may not always be made, so design moments may show a moment about the z axis, and axial force/moment charts may show a moment angle not equal to 0 degrees.
    [NCR21] (Fixed 17 May 2005; released in Adc.exe 8.0.5.0 and AdcData.dll 8.0.6.0)
  • AdCol gives incorrent results when a user defined reinforcement or concrete materials are used.
    [NCR36] (Fixed 7 July 2005; released in Adc.exe 8.0.5.0)
  • ADC corrects the sign of column moment results incorrectly when reading and writing via AdExport during automated testing. This affects comparisons of test results only, and not results that are evident to the user via the program's interface.
    [NCR46] (Fixed 10 November 2005; released in AdExport.dll 8.0.5.0)

    [NCR12] (Fixed 9 December 2004)
  • Program help contains a beam design example whose diagram, text and input data are inconsistent.
    [NCR13] (Fixed 11 December 2004)
  • The user-specified factor to be applied to the area of reinforcement is applied incorrectly to the bottom, mid-span reinforcement always, rather than to all tension reinforcement. It is also applied to areas of shear links. This bug-fix removes this factor altogether.
    [NCR14] (Fixed 16 February 2005)
  • ADC may propose a design that has longitudinal bar sizes that are smaller than the user-specified minimum.

  • ADC crashes when trying to create an output view for a model with notional loads.
    [NCR 1]
  • The design stage may give inconsistent bar sizes in spans over and immediately either side of columns.
    [NCR 2]
  • The area of reinforcement required at the ends of slabs that are supported by beams may be calculated incorrectly using a lever arm based on the depth of the supporting beam. The effective depth at these points may be reported incorrectly.
    [NCR5]
  • Span/Effective Depth calculations may give incorrect results when hogging moments produce a greater requirement for tension reinforcement than do sagging moments at the relevant position of the beam or slab.
    [NCR6]
  • The reported value of Basic Span/Effective Depth Ratio for cantilevered beams with non-rectangular sections may be incorrect.
    [NCR8]
  • When a data file that contains a beam with a General I Section is opened the width of the bottom flange is set to the width of the top flange.
    [NCR9]
  • Structures with final spans supported by both (a) an upper column whose end condition is encastre and (b) a lower column whose end condition is pinned, may be analysed incorrectly as pinned at both ends.
    [NCR10]
