With OBD CE 2021 Release 2 and RM Bridge v11.13, the User can design one PS slab with circular holes. In OBM, the User should choose a CIP bridge type and work with Place Advanced Deck. For the structural analysis and design, the User can send the…

RM Bridge Errors and Warnings create a list from the calculation processing to allow users to search for possible faults or misses, and notices of alarms for materials limits. More information can be found in the Recalc log that creates a .txt fi…

This RM Bridge FAQ: Influence surfaces example has a .pdf document and .tcl files to show how users can: use the i nfluence surfaces for transversal analysis; use influence surfaces for the traffic load evaluation of wheel loads on grillages; …

Influence surfaces for consideration of laterally distributed loads, or two-dimensional load trains, can be defined in RM Bridge by defining and assembling a set of parallel influence lines. The Default is to have the input Surface as an empty variable…

Due to the consideration of time effects and the respective active loads and elements in the construction simulation of bridges with concrete elements structural engineers, in general, understand that the final stage design of a bridge might be quite…

A detailed camber analysis within the construction schedule is also possible, with the action DoCamber for each label or type of load. This is very useful for construction control where the contractor will check the design pre-camber curve against each…

The Partial Twin Leaf Pier Bottom Connections could be modeled by attaching the Previous full Cross-section to the new Double Leaf CS thru its nodes. As shown in the picture below, the best practice is to use different node numbers and use rigid links…

In OBD CE 2021 Release 2 and RM Bridge v11.13 was improved “ RateF” schedule action for Imperial Units. “RateF”, evaluates the load rating factor for the bridge structure according to AASHTO code. This action is currently only applicable for steel and…

In RM Bridge the standard design processes begin with preparing a structural model, defining the loads, and the construction schedule for the erection stages. Then, two result types of the computer mathematical model analysis are of main interest: …

In RM Bridge the optimization of design parameters is done with the AddCon Method . The Additional Constraint Method is a solution for optimization problems in general within structural engineering. It is known as an extension of the Unit Load Method…

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…

The Demo Example number 9. Flexibility & Stiffness Matrix has an example of how to group elements to represent their structural behavior. In general, it is very useful for large projects to reduce the size of the model and therefore the computational…

As shown below, in RM Bridge the Analyzer Model View in Modeler is usually shown at the bottom left corner as an indicative of the structure the user is working on. It can be a useful reference when the user is working on the dataset, adding or modifying…

Modeler Main Girders are in general the superstructure elements created with longitudinal segments using as reference axis the road alignment or a local simplified version of it. They can be referenced to the Base Segment or Point Segment and have additional…
