CONCISE BEAM MAJOR IMPROVEMENTS (Since Version 4.0) VERSION 4.66 (August 31, 2023) - Openings in a beam segment can now overlap along the length of the segment. - 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 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. - Added option to limit Summary Report to output tables only. - 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. VERSION 4.65 (January 12, 2022) - Added the changes in amendment 2 to AS3600-2018. - Added optional flexural strength check at CIP Placement stage. - Added optional shear strength check at CIP Placement stage. - Added ability to input pre-defined load distribution factors for the CSA S6 highway live load. - Improved support for CSA S6-19 including interface shear. - Added cellular beam and trapezoidal girder to section templates. - Added calculation option G5 to allow flexural load distribution narrower than the beam. - FLS (fatigue) reports now available for all codes. - New option to limit travel of udl portion of moving live load (e.g. lighter traffic) same as truck. - Improved PCI hollowcore load distribution to account for the location of distributed loads within a cantilever. Previous versions of Concise Beam used the full cantilever length to determine the load distribution. VERSION 4.64 (2020) - Added AS3600-2018, ACI318-19, CSA A23.3-19, and CSA S6-19. - Added ability to over-write fr (flexure) in the concrete dialog. - Implemented ACI minimum flexural steel for non-prestressed beams. - Added option (F10) to use prestressed minimum flexual strength (1.2Mcr) for non-prestressed Beams (ACI only). VERSION 4.63 (2020) - PCI & CPCI analysis and checks for walking and rhythmic vibrations. - Vibration limits from CSA-S6 to the deflection table. - Option for over-stress allowance of ULS checks. - Option to design interface ties separate from stirrups. - Option to use full CIP pour as effective in flexure. - Option to make CIP pour non-composite. - Option to waive minimum shear steel requirement based on tests where allowed. - Option to use full strength of hollowcore fill when shear strength of precast plank is reduced for lack of minimum required shear reinforcing. - Generated self-weight load groups added to Applied Loading dialog. - Option to paginate text reports for printing. VERSION 4.62 (2018) - PCI Hollowcore Distribution for Cantilevers - Effective Width of Cast-In-Place Pour - Spancrete Method for Hollowcore Fill Shear Reinforcing - Fractional Number of Strands and Reinforcing Bars - PCI and CPCI Stress-Strain Curves for Prestressed Stress-Relieved Strand, Wire and Bars - CSV Export for Loading, Reinforcing, and Core Fill VERSION 4.61 (2017) - Discrete Shoring Points - Limits On Travel of Moving Load - Maximization/Minimization of Load Effects - New Standard Section Generator - Trim a Section to Width or Height - First Flexural Frequency - Option for Non-Composite Section for Shear Depth - Metric (MKS) Units - Check for Rupture of Steel in Flexural Capacity - S6 Cracking Method VERSION 4.60 (2016) - Added ACI318-14, CSA A23.3-14, and CSA S6-14 - Flexible Loading Groups - Area Loading - Moving Loads - Highway Live Loads and Load Distribution (CSA S6) - Vertical or Horizontal Through Openings in Beam and Cast-In-Place Pour - Generate a Harp Strand Profile - Non-Uniform Stress Block for Flexure - Shear Stirrups and Horizontal Interface Ties Have Been Separated - Bursting Steel Requirements VERSION 4.59 (2013) - Check Principal Stress for Vcw (ACI) - Support Rotations and Beam Length Change - Shear Strength Provided by Filling Cores in a Hollowcore Plank - Long-Term Deflection Multipliers for Prestressed Beams Based Actual Beam Characteristics - Slipped Strand Can Carry Load - Added Section Type VERSION 4.58 (2012) - Added ACI 318-11 - Lateral Beam Stability Checks During Lifting and During Transport by Truck - Stress Check During Transport by Truck VERSION 4.57 (2011) - Added AS3600-09 - Unicode Support - Cracking Analysis for FLS Loading VERSION 4.50 to 4.56 (2009 - 2011) - Added ACI 318-08 and NZS 3101.1:2006 - New Libraries - Zia/Hsu Torsion Method - More Flexible Cast-In-Place Pour - Welded Wire Reinforcing VERSION 4.47 (2007) - Load Distribution Including PCI Hollowcore Distributions - Lifting Load Case VERSION 4.40 to 4.46 (2006) - Added ACI318-05 and CSA-A23.3-04 - Added ACI318-99 Appendix B - Added PCI Standard Design Practice TR-7-05 - Bearing Width VERSION 4.30 to 4.39 (2005) - Deflection Calculation at Completion of Construction - Added AS3600-2001 VERSION 4.20 to 4.24 (2004) - Check for Slipped Strand and Rebar in Flexure VERSION 4.10 to 4.19 (2003) - Added ACI318-02 - Transformed Section Properties VERSION 4.0 (2002) - New 32-bit Windows Interface with Context-Sensitive Help - Calculates Shear, Interface, and Torsion Reinforcing Required - PCI Loss Method - New Crack Analysis - Tensile Rebar Required at Transfer [Change in ownership of Concise Beam from CPCI to Black Mint Software, August 2002]
