To create prestressing tendons in RM Bridge inside OpenBridge Designer users have two workflow options: Usual : to create the input by the Graphical User Interface, in OpenBridge Modeler or RM Bridge Modeler and RM Bridge Analyzer GUI, or; Fast…

The Tendon load definitions are a series of prestressing cable stressing actions at their ends. For each side, the PT cables (Tendons) can be: PRE: prestressed, stressing; REL : releasing ; SWED/DEVL: length of wedge or development slip: These…

OpenBridge Designer is a suite of products that encompass both the modeling and design of bridges. OpenBridge Designer CONNECT Edition is a unique application that combines modeling, analysis, and design into one comprehensive bridge product. The application…

The RM Bridge Analyzer: Properties: Cross Sections: FE Mesh Move and Rotate the Nodes is a button with an option to modify current cross-section properties to achieve specific purposes. It is important to note that this function is principally related…

Currently, there is only one link between OpenBridge Modeler and the Standalone applications, with a single .DGN file for OBM and one directory for the apps. It allows any modification to be synchronized between them with a single source of information…

For RM Bridge inside OpenBridge Designer , the Schedule Variants options for the Analyzer portion allows users to create different analysis variants definitions for the same structure. One project might require additional structural analyses but could…

As seen in the screenshots below, the Network Arch Bridge has the characteristics of numerous inclined hangers and usually a much more slender and a little lower arch due to its efficiency in load distributions. Multiple possible solutions exist to model…

For RM Bridge inside OpenBridge Designer , as shown in the pictures below, the Friction Pendulum System - FPS - is a support device that provides the structure with some level of Seismic Isolation , it is also known as High Load Multi-Rotational - HLMR…

The RM Bridge Analyzer: Properties: Cross Sections: FE Mesh menu options displays elements and nodes of the Finite Element mesh of the cross-section. Each cross-section is subdivided into 9-noded Finite Elements. The mesh is used for calculating the cross…

Stress Ribbon Bridge The stress-ribbon bridge is the modern analogy to the rope bridge; tough, it's considered very desirably due to its quite attractive aesthetic. it's usually applied to pedestrian bridges, where the vertical forces are less demanding…

RM Bridge inside OpenBridge Designer can calculate or define the Aerodynamic Admittance functions for the fluctuating wind buffeting forces for different mean wind incident angles of attack, as shown in the image below. The frequency-dependent aerodynamic…

Inside File\Examples\Demo Examples & FAQ users will find the Frequently Asked Questions and Solutions section for RM Bridge in OpenBridge Designer . It has CFD capabilities that allow the simulation of static wind coefficients thru Computer Fluid Dynamics…

Traffic Evaluations use the Sup action Rules to combine all possible different loads into one final Traffic Envelope. While the Action Infl creates the unitary influence lines, the LiveL applies the Load train to these influence lines generating the Envelope…

For any grillage modeling, there are two fundamental aspects to be taken into account: Proportions & Arrangements Proportions : The element's lengths of the grillage should be similar, i.e., the longitudinal and transversal girders' distances should…

The Bridge products will perform optimally if the recommended System requirements as outlined below are adhered to. Processor Intel Pentium-based or AMD Athlon-based processor 2.0GHz or greater Operating System Windows 10 (64-bit) Memory 16GB…

In OpenBridge Designer Connect Edition, it’s possible to run RM Bridge in a completely standalone version. In this way, during the analysis, the User is now able to run several different inputs *.tcl files and/or use the batch mode run. The project…

OBD CE 2022 Release 1 and RM Bridge v11.14 is now able to compute and allow access to shell forces, stresses, and displacement results corresponding to integrals of lead components in a finite element model, after a live load analysis is performed. …

OBD CE 2022 Release 1 and RM Bridge v11.14 is now able to compute and allow access to shell forces, stresses, and displacement results, for Live Loads analysis. After running a FEM Live Loads analysis, the User can obtain: 1. Curve Diagrams Live…

We proudly announce that OpenBridge Modeler (10.11.00.310) and OpenBridge Designer (10.11.00.40) for our 2022 R 1 release is commercially available to download. As always in our OpenBridge releases, this is considered a major release: Bridges created…

In OpenBridge Designer and RM Bridge is presented one local finite element model for a Steel Voided Diaphragm analysis. The parametrized model uses variables definition in RM > Modeler. Vertical loading, the stress state analysis obtained is presented…

While a perpendicular line defines the position of the stiffeners within the element faces, t he stiffener's perpendicularity is normal to the line between the cross-section element face's beginning and end nodes. Therefore, there is always the assumption…

RM Bridge allows for creating Cross-section details like longitudinal Stiffeners for steel plate elements. Placing stiffeners is done inside Modeler , at the Cross-section edit window and four different shapes are available: U: create U-shape stiffener…
