Stress : Activate and calculate…
For RM Bridge inside OpenBridge Designer at Analyzer Analyzer /Schedule/Stages/Schedule Actions: user will find the Action to activate the cable in the right construction schedule, this will calculate internal primary forces of tendons by stepwise applying…
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 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…
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…
Hi,
I have question regarding calculation of minimum reinforcement in RM Bridge.
In schedule action I put robust check and note that the detail list file to be provided. The thing that confuses me after opening the detailed list file is formula…
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.
…
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…
To define the Schedule, the usual workflow in RM Bridge is the following:
Select Schedule > Stages > Activation: to define elements to be activated or deactivated in the stages.
Select Schedule > Stages > Tendon Actions: to define the actions that…
The Loads definitions in RM Bridge inside OpenBridge Designer generally follow the workflow below:
Select Schedule > Load Definition > Load Set to split the applied loads into logical sets of loads.
Select Schedule > Load Definition > Load Case…
The Load Set Definition is used for previously grouping common load definitions for more complex analysis. This can be more advantageous than entering the load data directly in Load Case Definition because the Load Sets can be later assigned to the load…
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…
