Changelog:
- Added support for CSA A23.3-24.
- Added support for CSA S6-25.
- Added support for ACI 318-25.
- Added support for ACI 319-25 as an calculation option (G2) when using ACI 318-25. This calculation option will continue to use the recommendations in the PCI Standard Design Practice document for earlier releases of ACI 318.
- Added batch analysis facility to generate Summary Reports.
- Added a calculation option, S14, to control the inclusion of a clamping force due to dead load for interface shear.
- Updated the reinforcing development length report.
- A new file format has been created for the problem files to accommodate additional data used by the program. It still uses the *.con extension but cannot be read by versions of Concise Beam prior to version 4.70. Version 4.70 will read files created by Concise Beam version 2.x, 3.x, and all prior versions of Concise Beam 4.x. Files will now be saved in the new file format.

Version 4.66L
December 18, 2024
View Changes
Changelog:

- Corrected an error in the calculation of the shear steel spacing for shallow beams designed to AS3600:2018.
Version 4.66j
September 25, 2024
View Changes
Changelog:
- Corrected an error in the calculation of the structural depth, d, for interface shear strength under the CSA codes.
Version 4.66i
July 11, 2024
View Changes
Changelog:
- Corrected an error in the shear strength check of the minimum flexural strength waiver under the ACI codes. This error would only occur if calculation option F9 is used.
Version 4.66h
May 22, 2024
View Changes
Changelog:
- Corrected the text report for the CSA S6 live load distribution report and distribution at FLS.
- Concise Beam will now change the CSA S6 load distribution to suit the selected S6 design code if a moving load is defined and a non-S6 distribution is not selected.
- Beams that require a torsional analysis can now be analyzed in most situations without entering torsional reinforcing parameters. This allows the user to check whether the torsional load exceeds the threshold torsion of a beam that can't be easily reinforced for torsion. The parameters will still need to be entered to check any required or provided torsional reinforcing. Some torsional parameters will still need to be entered to check the threshold torsion under AS3600 or ACI 318 using the Zia-Hsu method.
Version 4.66g
April 23, 2024
View Changes
Changelog:
- Corrected a unit conversion bug in the determination of whether minimum shear reinforcing is required that may affect non-prestressed beams (not slabs) designed to ACI318-19. It may also affect beams with steel-fibre reinforcing designed to ACI318-14 or ACI318-19.
Version 4.66f
April 4, 2025
View Changes
Changelog:
- Added an additional graph, "Torsion - Final Service", for the torsion design check. It illustrates the existing "Torsion Check - Final Service" text report.
Version 4.66e
February 13, 2024
View Changes
Changelog:
- Cleaned up negative flexural checks where significant flexural is not present.
- Corrected the code reference for over-reinforcement in AS3600-09 and AS3600-18.
Version 4.66d
January 10, 2024
View Changes
Changelog:
- Rebar groups with straight end embedment can now be specified as bundled. All of the bars within the group are assumed to form a single bundle. The number of bars in the bundled group will be limited to four in accordance with the supported design codes. Bundling the bars may increase the tension and compression development length of the bars.
- Corrected composite section properties for cast-in-place pours with a negative haunch height.
Version 4.66c
December 8, 2023
View Changes
Changelog:
- Corrected the amount of shear steel needed where at least minimum shear steel is provided but not required. This may affect problems checked to codes where Vc is based on whether minimum shear steel being provided (CSA A23.3 & S6, ACI318-19, AS3600-2018).
- Corrected a bug that may cause the program to crash when leaving the Beam Definition dialog without defining beam segments.
Version 4.66b
November 16, 2023
View Changes
Changelog:
- The "Fill Cores for Shear Strengthening" option in the Shear Strengthening dialog is now ON by default.
- Concise Beam will no longer calculate the number of hollowcore voids that would need to be filled to provide the required strength. Differing void sizes within a section make this calculation unreliable. The program will now simple report the total area or width of void fill required within the section to meet the required strength depending on the calculation method selected. When specifying the cores to be filled in the Hollowcore Parameters dialog the program will calculate the total fill area or width for the filled voids selected for comparison with the required value.
- Filled cores that are interrupted by openings have been corrected. Note that a filled core that is partially cut away by an opening will not be considered filled at the opening as the fill will not be fully supported.
- When importing precast cross-sections into a library file from the currently open problem file you will now have the option to also import sections automatically created by the program, such as at an opening.
Version 4.66a
September 11, 2023
View Changes
Changelog:
- Fixed problem with the use of cracked section properties for non-composite cracked beams.
Version 4.66
August 31, 2023
View Changes
Changelog:
- Added option to limit Summary Report to output tables only.
- Openings in a beam segment can now overlap along the length of the segment.
- Added additional section properties. The height from the bottom at which superimposed loads are applied to the section are now estimated for section with bearing ledges or can be specified by the user. This height may affect the location of the critical section in shear. The height of the top of the web is also estimated or can be specified by the user. This height can be used to calculate the location of the principal web stress in the ACI codes. The program will now also calculate the lateral moment of inertia Iy, the product of inertia Ixy, and the resulting angle of the principal axis from horizontal (for asymmetrical sections). These values are largely for future use though the principal axis angle can be useful for manually rotating the section being checked to the principal bending plane if the section is not restrained to bend vertically. A precast stadia unit is an example of this kind of section (e.g. Example 3-04 in the CPCI Design Manual, 5th edition, or Example 5.2.5.1. in the PCI Design Handbook, 8th edition). Concise Beam does not automate this rotation.
- Text and graph windows that remain open after the problem model has changed are marked "Not Current" to indicate that the displayed results may no longer be valid. The non-current windows may be useful when comparing older results against newer result windows after the model has changed and been re-analyzed to see the incremental change. A new option has been added to the Solution menu (and the toolbar) that allows the user to update opened text and graph windows that are non-current by reanalyzing the problem and updating the results in those existing windows. This allows the user to layout the text and graph windows of interest on the screen without having to reopen and layout those windows again after a change in the model and reanalysis.
- Added allowance for negative load factors.
- Exported text files now include an identifying header and are saved to a subdirectory named after the problem file. This same directory is also used for exported input details.
- Better support for cracked sections at the time of the cast-in-place pour.
- Paginated text report windows now display the current page number.
- Adjusted maximum interface shear force for the moment region method.
- Improved compilation of minimum effects in load envelopes.
- Clarified stress "limits" for non-prestressed beams.
- Improved identification of sections that are hollow for torsion in order to use tubular model.
- A new file format has been created for the problem files to accommodate additional data used by the program. It still uses the *.con extension but cannot be read by versions of Concise Beam prior to version 4.66. Version 4.66 will read files created by Concise Beam version 2.x, 3.x, and all prior versions of Concise Beam 4.x. Files will now be saved in the new file format.
