RM Bridge Enterprise Program Settings is accessible to the users at the Top Home Ribbon Menu, as shown in the screenshot below. Program Settings allows users to set up the program configuration for: Language : Dialogue and Output Editor path : direct…

RM Bridge Verification Examples are a list of common simple practical bridge modeling issues that are examined, tested and proof within the application, it includes the examples as shown in the list and the screenshot below: Euler Buckling of a…

The objective of this Verification Example of a Snap Through Problem at a Pin-joined Arch is to perform a post-buckling analysis of a typical roof structure, a pinned "linearly arched" structure, using IIIrd Order, the large deflection method, as well…

In this video is presenting the Last Construction Stage after the concrete slab is hardened and composite elements activated. It is introduced the load cases for deck wearing surface and utilities, the earth pressure behind abutments, the transferring…

In RM Bridge Enterprise > Modeler > Cross sections, the User can define the finite shell elements in the deck slab. The User can edit shell elements for assigning variables to slab thickness, if desired and review the information introduced. In…

In RM Bridge Enterprise > Analyzer, were defined the several Construction Stages considered in the bridge built and until the composite is activate (before concrete slab is hardened). Presented below the different construction stages calculated. STG01…

In RM Bridge Enterprise > Modeler, was defined the completely geometry for an Integral Steel Composite Bridge. In this video series, it is presented the structural analysis and design for this type of bridges. The deck cross-section is defined with…

RM Bridge is now an integral part of OpenBridge Designer CONNECT Edition as Bentley’s solution for supporting the design and engineering tasks in bridge construction for all types of bridges and construction methods in 4D (including time domain) and all…

In schedule action “UltSup” with Reinforcement design selected, program calculates the necessary reinforcement area amount, required for the ultimate check capacity of the cross-section. Presuming a plane strain over the cross-section, and a nonlinear…

In RM Bridge Enterprise, User can perform the ultimate limit check for a specified envelope based on the stress-strain diagrams of materials and calculates, if requested, the required reinforcement amount ( ULS reinforcement design ). The following…

In RM Bridge Enterprise, User can obtain the detailed steel check report with all the calculations performed by the software with “UtlRes” schedule action. In Analyzer > Structure > Checks, User can select elements for the analysis and ask for the detailed…

In RM Bridge Enterprise, User can perform the calculation of the cross-sections class and design resistance of steel and composite steel sections with consideration of local buckling of slender cross-section parts (slender parts). Characteristic buckling…

When RM Bridge Enterprise is started, the most recently used project directory is automatically allocated. This option allows for switching to another working project directory. Making a New Folder and continuing the work in a new working project…

In RM Bridge Enterprise, User can have access to several different types of demo, verification and training examples available for downloading, with model analysis and documentation. A subdirectory of the current project directory is normally created…

In RM Bridge Enterprise > File > Initialize Current Project, the User can define and modify the basic settings for processing and calculating the bridge project, e.g. user inserts descriptive and identifier project titles, applicable design code and material…

As we know one of the greatest advantages of RM Bridge is the reuse of data from similar projects. If this is done a lot of time can be saved by using already previously checked input. But additional verifications could then be required to make sure the…

New schedule action for plotting ultimate bending capacity in the cross-section for load cases and envelopes is now available. Users can now plot the list files results (.lst) and will be able to quickly check if the ultimate capacity is achieved in the…

A new option in the “Cross section point selection” dialog, under Tendon in the RM Modeler, which allow Users to generate the same tendon geometry for all other points inside of the grid pint group is now available.
