For RM Bridge, inside OpenBridge Designer, at Analyzer Analyzer/Schedule /Load Definition/Tendon Load the users will find the internal PT cable loading actions to be defined within a group of prestressing tendons defined by the selected Stress Label …

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…
