Composite structures loads considering the erection sequence in the simulation with partially completed elements has a complex structural system that changes in time and requires a non-linear stress distribution as shown in the picture below. This…

Within the RM Bridge Demo and FAQ, there is a quite versatile one: TCL Examples has multiple files with the objective to demonstrate the potential of the programmable script languages for RM Bridge . The .tcl format creates backup files, in the ASCII…

For Composite Structures one additional design task is the dimensioning of the Shear Studs. This can easily be achieved in RM Bridge by adding a series of longitudinal static spring elements in the girders to simulate this and extract the Normal forces…

Inside File\Examples\Demo Examples & FAQ user will find the Frequently Asked Questions and Solutions section for RM Bridge Enterprise . As shown in the screenshot below, user can select the T-beam model as a reference entitled Concrete Structures - Ultimate…

RM Bridge load manager is a very useful tool for the automatic superposition of load cases . This Load Management function can be found at Analyzer\Schedule\Load definition\Load Management and is provided particularly for speeding up the necessary definitions…

Load Management: this table of load case categories allows for an automatic superposition of load cases into summation load cases and envelopes. It is a previous step before the usual Load Combination that allows for grouping similar results for a stage…

STG-SUM , or Stage Summation Load Case is a very useful tool in RM Bridge for the analysis of construction stages. It is usually created in the Load Management; while other summation load cases are also possible, like SW-SUM, PT-SUM, CS-SUM, SDL-SUM;…

Question How are elastic compression losses in tendons due to initial pre-stressing and subsequent loads handled in RM Bridge? Where can I see the results, in particular due to stressing of other tendons and due to time-dependent effects of creep, shrinkage…

What's New in OpenBridge Designer CONNECT Edition 2021 Release 2 (March 2022) This topic summarizes the new enhancements in OpenBridge Designer (OBD) CONNECT Edition 2021 Release 2 (v10.10.20.34) and its components OpenBridge Modeler (OBM), RM Bridge…

RM Bridge Loads can be specified with Factors and this could be assigned to Variables that might be associated with either Expressions or Table values. This is very useful for easily create several dynamic loads as only one. Load Sets can then also be…

Here we will discuss the FAQ about Reports and Drawing s in OpenBridge Modeler. Analysis and Reporting Ribbon Tab (bentley.com)

Create Drawings in OpenBridge Modeler is a tool to Create Substructure Drawings automatically with a few settings. More specific information can be found at the Help/F1 link below and an example at the YouTube video at the next link. Create Substructure…

A quite common first-time users question is when the section is not showing up in your Dynamic Drawing model, as in the screenshot below. There are many possibilities; but, one common situation is that the user is not aware of the seed and the settings…

RM Bridge can consider Variable Loads in many different ways, in time and space. For the loads to be variable either one of the options below should be selected: Var-Fac , the Variable factor is usually for Time History calculations, a corresponding…
