Concise Beam V4

Concise Beam V4 is an easy to use program for the design of precast concrete beams. Concise Beam will perform a load analysis and design checks in accordance with the latest edition of ACI 318, CSA A23.3 & S6, AS3600, or NZ3101.1. The beam can be conventionally reinforced, partially or fully pretensioned. It can model any cross-sectional shape and will allow the cross-section to vary prismatically (step-wise) over the length of the beam. A graphical editor allows the user to describe any cross-section, including voids.

Concise Beam works in two-dimensions using simple beam theory (ACI B-region) including longitudinal torsion along the beam. Concise Beam is NOT able to perform any analysis or design checks required for disturbed regions (ACI D-region) such as at sudden changes in section, large openings, notches, or dapped ends. The user can work in metric or U.S. Customary (Imperial) units, with a variety of individual units (i.e. mm, cm, m), and switch back and forth at will. Libraries of industry standard cross-sections and materials are provided with Concise Beam. The standard libraries can be modified, extended and customized by the user.

Concise Beam is designed to be used solely by, or under the direct supervision of, a qualified structural engineer. Concise Beam cannot protect against an unsafe beam design if the beam is modelled incorrectly or is beyond the scope or capability of the program.

November 15, 2023 - Concise Beam version 4.66b is now available for download

YOUR COMMERCIAL LICENSE MUST BE CURRENT UP TO THE END OF NOVEMBER 2023 AT THE EARLIEST TO BE ABLE TO USE THIS RELEASE. Users evaluating this new release will be able to use this version for the remainder of their 30 day evaluation period. If your license has expire please contact me about how to bring your license up to date in order to use this latest release and to receive technical support. You do not need to install any previous versions of Concise Beam before installing this latest release.

Version 4.66b is a maintenance release which includes the following changes;

• 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.

September 11, 2023 - Concise Beam version 4.66a is now available for download

YOUR COMMERCIAL LICENSE MUST BE CURRENT UP TO THE END OF SEPTEMBER 2023 AT THE EARLIEST TO BE ABLE TO USE THIS RELEASE. Users evaluating this new release will be able to use this version for the remainder of their 30 day evaluation period.

You do not need to install any previous versions of Concise Beam before installing this latest release.

Version 4.66a is a maintenance release which includes the following changes;

• Fixed problem with the use of cracked section properties for non-composite cracked beams.

August 31, 2022 - Concise Beam version 4.66 is now available for download

YOUR COMMERCIAL LICENSE MUST BE CURRENT UP TO THE END OF AUGUST 2023 AT THE EARLIEST TO BE ABLE TO USE THIS RELEASE. Users evaluating this new release will be able to use this version for the remainder of their 30 day evaluation period. If your license has expire please contact me about how to bring your license up to date in order to use this latest release and to receive technical support. You do not need to install any previous versions of Concise Beam before installing this latest release.

Version 4.66 is a major release which includes the following changes;

• 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.
