RAM Structural System CONNECT Edition 15

RAM Structural System CONNECT Edition 15
New Features and Enhancements

Several significant enhancements and features have been implemented in RAM Structural System CONNECT Edition Release 15.0. This version is now available.

The Release Notes can be found at the wiki RAM SS V15.00 Release Notes.

The latest family of Bentley products are now identified as CONNECT Edition. All of Bentley’s CONNECT Edition programs, including the RAM Structural System, allow models to be associated with a project. Multiple models, from any of the Bentley products can be associated with a given project. This simplifies the process of keeping track of work done for a project, and in the future will enable analytics to be performed and reported for the project. When a model is first created or opened in this version the program will ask for a Project to which the file is to be associated.

See the wiki article Bentley CONNECT Overview for a more complete description of Bentley CONNECT. There are important instructions on registering users, creating projects, and associating models with projects.

Personal Portal
When you sign in to your Bentley account you now have easy access to your Personal Portal. The personal portal gives you easy access to Usage reports, site configuration information, downloads, and Learning information on webinars, seminars and events, and includes a transcript listing the Bentley courses that you have completed. Your personal portal also lists your recent projects with a portal into analytics on that project.

Eigenvalue Analysis
A new option for performing the Eigenvalue analysis (periods and modes) has been added, Lanczos Eigenvalue solver. The new solver has some remarkable advantages over the other two solutions: the new solver is much faster than other two solutions (i.e., subspace iteration and Ritz vectors solution) and it consumes significantly less memory and it is a very robust solution (the Lanczos implementation is an open source code developed by Rice University and widely used in academia and in industry).

ACI Beam Design Bar Selection
If the optimized number of longitudinal bars for beam capacity are not sufficient to accommodate all of the vertical shear bars the program will reduce the longitudinal bar sizes and add bars sufficient to accommodate all of the shear bars. When Analyzing user-specified bars in View/Update, if there are insufficient longitudinal bars for the number of shear bars the program will warn the user. The user can then either proceed as is or add additional bars.

CAN/CSA A23.3 Beam Skip Loading
When beams are designed per CAN/CSA A23.3, live loads are now skip loaded (pattern loaded).

Shear Reinforcement
For CAN/CSA A23.3 and BS 8110 the shear reinforcement design, including bar sizes and spacing, hooks, and shear zones can be modified and analyzed in the View/Update dialog.

Concrete Beam DXF
The sections in the concrete beam DXF file now show the correct link type and the number of legs with appropriate hooks.

A significant number of enhancements and improvements were made to the ISM capabilities that all models to be shared with Bentley’s BIM software AECOsim Building Designer, analysis and design software such as STAAD, and detailing software ProStructures. Together with the recently updated ISM Revit Plugin the interoperability with Autodesk’s Revit has also been enhanced. Some of these enhancements are listed below:
The RAM Structural System supports the concept of a typical floor type, but other software does not. This necessitates the splitting of typical floors into individual floor layouts when exporting a model from the RAM Structural System to an ISM repository. The user is now prompted before the typical layout used at multiple levels is split into unique layouts.
In the ISM import and export, an option to specify a model rotation has been added. This allows, for example, the ISM model to be oriented in its true orientation but oriented conveniently orthogonal to the X- and Y-axes in the RAM Structural System model.
When creating a repository an option has been added to split beams with cantilevers into separate elements in the repository, the main span of the beam and the cantilevers, broken at the supports. If the option is not selected the beam will be defined in the repository as a single beam cantilevering over/through the supports.
When creating or updating a repository an option has been added on the Operation Settings tab of the Mappings dialog to lower the elevation of beams that support Steel Joists by an amount specified, enabling the lowering of the supporting girders by the seat depth of the Steel Joists. Previously these beams would have to be manually adjusted.

Creating or Updating a repository would cause the analysis and design of a RAM Structural System model to be invalidated. The analysis and design results are no longer invalidated when a repository is created or updated.
In the File – ISM – ISM Options command there is now an option to open the Structural Synchronizer when using New from Repository. The benefit of this is that the user can manually filter out by rejecting objects they do not want imported into the model file.
Beam Reactions can be included when exporting to ISM. Now in the File – ISM – ISM Options command there is the ability to round the values to the number of decimal places specified by the user.
