Release Date: August 2023
Version: RAM Concept 2023
Version Number: 23.00.00.81
This release of RAM Concept adopts a new year-based naming convention that is consistent with industry practice. The previous version of RAM Concept was Version 8 Update 4 (v08.04.00). This release is RAM Concept 2023 (v23.00.00).
Installation files for current and past RAM Concept releases can be downloaded from the Bentley Software Downloads page. After signing-in, the RAM Concept installers can be located by selecting RAM in the Brand menu and clicking Apply or searching for RAM Concept in the Product Search box.
This version of RAM Concept cannot be installed through the CONNECTION Client update service or through the Structural WorkSuite Hub. Subsequent update releases for the RAM Concept 2023 series will be made available through these applications.
RAM Concept 2023 can be installed concurrently with previous versions of RAM Concept. Installing this version will not automatically uninstall any previous versions of RAM Concept.
In April 2023, the RAM Concept Post Tension Module license/subscription was merged with the base RAM Concept license/subscription.
As part of this product licensing change, existing contract quantities of the base RAM Concept license were automatically converted to the new, consolidated RAM Concept license. There was no upgrade fee for this license conversion.
This change affected all accounts owning RAM Concept perpetual licenses under a SELECT subscription or RAM Concept Virtuoso subscription. The change did NOT affect accounts that access RAM Concept through the Structural WorkSuite license, including enterprise accounts (E365/EPS 365 or ELS subscriptions).
All RAM Concept users are now entitled to all RAM Concept product features, including the post-tensioning (PT) features, even if their organization did not previously own the RAM Concept Post Tension Module.
More information on this licensing change can be found here.
The Early Access Program (EAP) for the iTwin Synchronize to Cloud Workflow continues with this version. A practical application of this technology is the ability for RAM Concept users push PT tendon profiles to a 3D analytical iTwin and review those profiles in elevation/cross section views across the floor as shown in the image below.

The tags in the image highlight tools and features available in this workflow:
RAM Concept users can participate in the EAP and access the capabilities available in this workflow at no additional charge. More information on registering in the EAP can be found here.
RAM Concept 2023 includes the enhancements discussed below.
Tendon Property for Duct Centroid Location
PT tendon object properties now include a parameter that defines the vertical offset between the strand and duct centroids. RAM Concept users can utilize this property to determine chair height elevations for bonded PT systems and verify duct cover requirements using iTwin workflows.
This property is available for all tendon objects, including banded tendon polylines, distributed tendon quadrilaterals, and manual tendons.
The offset property does not currently affect the design of PT concrete sections or the visualization of tendon profiles in RAM Concept.

PT System Material Changes
The definition of PT Systems in the Material Specification table (Criteria > Materials) has changed. PT Systems properties are now organized by strands, ducts, and anchors. New properties, which define the geometry of ducts and anchors, have also been added.
New PT System properties include:
None of the added properties currently affect the design of PT concrete sections in RAM Concept. The purpose of the new PT System properties is to represent the tendons better graphically in the iTwin workflows.

Graphics Improvements for High-Resolution Displays
RAM Concept now automatically scales graphical user interface items, like text and tool buttons, based on the pixel density of the display. Without the scaling, tables and buttons were unreadable when using RAM Concept with high-resolution displays.
RAM Concept 2023 also includes the changes discussed below.
Component Upgrades
Several internal program components are updated, including the following:
PT Design Optimization Genetic Algorithm Changes
In the previous version, the PT Design Optimization feature successfully found low-cost solutions, but did not effectively eliminate isolated failures in some cases. A minor change was made to the genetic algorithm to better resolve design code failures during the optimization.
New Default for Edge Treatment Property for Punching Shear Checks
Sector Voids is now the default option for the Edge Treatment Property for Punching Shear Checks. Failure Planes was used as the default option in previous versions.
The Sector Voids option decreases calculation time for punching shear checks that include multiple slab openings that are completed contained within the punch check search radius.
Ancon Shearfix Punching Shear Solution
The following changes were made to the Ancon Shearfix SSR System manufactured by Leviat:

New Installer Framework
RAM Concept now uses an installer framework that matches the installers used by other Bentley applications.
Manage License Restriction Option for Post Tensioning Features
The option to disable/enable access to the post-tensioning features (Help – Licensing > Manage License Restrictions) was removed from the program. This option is no longer needed following the licensing change noted in the “Product Licensing” section.
Bentley Cloud Service Menu
The Bentley Cloud Services menu was removed from the program. This menu included options for associating or disassociating “CONNECTED Projects” to RAM Concept model files. Project association is now handled through the iTwin Services workflow. The menu also included a link to the CONNECT Center. This web page can be accessed through the CONNECTION Client application.
RAM Concept 2023 includes fixes for the issues discussed below.
Deflection Checks with Segmented Span Segments and Skewed Sections
When spans were modeled with a series of segmented span segments and the orientations of the cross sections within the segments varied, the deflection check calculations were affected by the following issues:
Figure 5 - No Deflection Found for Point Inside Slab in Span Segment::deflectionAnalysis()
Critical Section Not Found for Punching Shear Checks Due to Skewed Slab Edge
In rare cases, no critical sections were found for punching shear checks near skewed slab edges. For affected punching shear checks, the warning below was generated during the analysis and no punching shear calculations were competed.
Figure 6 - No Column Critical Sections were Found at Punch Check
Copy/Paste Fails Intermittently
On isolated machines, the error below was generated when attempting to copy objects or perform a copy-move operation. In a few cases, no error was displayed but a program crash occurred.

Table Rows Obscured by Horizontal Scroll Bar
When a criteria table contained a single row and the table width exceeded the active window width, a horizontal scroll bar may have hidden the table row. When this problem occurred, the table data could not be viewed unless the table or window was resized or a row was added to the table.
RAM Concept 2023 can read all previous file formats but writes files in a format that cannot be read by previous versions.
