Boundaries are any border around elements of a cross-section, internal or external to the CS. The Boundary constraints are defined by a set of connected boundary line segments and the options are shown in the image below. More information about…

In RM Bridge circular elements and radial elements edges, as well as circular construction lines and arched boundaries can be created in Modeler, giving great modeling flexibility. Initially, users should know that there are new types of construction…

Now Available, the first Commercial Release of OpenBridge Modeler CONNECT Edition . v10.03.00.03. Bridge Modeling on the MicroStation CONNECT platform and OpenRoads with OpenBridge Modeler CONNECT Edition , OBM CE. Key Features: 3D parametric…

The RM Bridge model in Modeler is created with the assumption of one of the three possibles Cross-section planes for the elements in Elevation : Normal to element axis in Elevation : perpendicular to the defined local element axis, i.e., in the Local…

In RM Bridge inside OpenBridge Designer , the best practice for Diaphragms & Stiffeners is creating a separate Link segment for these elements. The Links can be accessed at the Main Girder menu, at the top right, as shown in the screenshot below. The…

In the RM Bridge inside OpenBridge Designer, the Modeler portion of the application allows the users to create virtually any Cross-Section geometry. The definition of cross-sections is independent of axes and segments as they will get connected to segment…

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…

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…

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…

The new Rail Structure Interaction Wizard in RM Bridge is a tool to facilitate the input of the additional elements necessary to model an RSI. It aims to ease the creation of tracks and spring elements to simulate the link of the rails and the bridge…

Main Girder is the segment type that is the principal for bridges, i.e., the longitudinal segments concomitant to the main Axis or Alignment and subdivided by a specified segmentation that will create a series of points or nodes. It usually has a cross…

In OpenBridge Designer , at the RM Bridge Modeler , by using the right-click mouse at the Cross-Sections list in the menu tree, it is possible to import existing or Read Cross-section from: Steel Profiles: I or T Rolled or Welded, L, U, C, Rectangular…

In OpenBridge Designer, within RM Bridge , the Modeler option is still very open and powerful, and it allows the users to create Suspension Bridge models. As shown in the images from the screenshots below, the simple suspension bridge modeling example…

In RM Bridge the definition of Cross Sections (CS) is completely independent of Alignments, Axes and Segments . Therefore it can be previously defined as cross sections will be later assigned to the respective Elements in the Segments definition to create…

At Modeler inside RM Bridge in the Cross-Sections , users can define Parts that are used to define the Beams and Nodes for the structural system to be used in the analysis and calculations. Although most models will have only one Part 1 that is pre-defined…

For modeling an inclined pylon in RM Bridge the user can either have the cross-section of the element in-plane, with the usual option of the cross-section plane horizontal, or perpendicular to the element axis. These inclined element cross-sections…

RM Bridge allows users to model any complex transversal supports or diaphragm thru the use of several Modeler axes. As usual, each Axis will create the necessary elements to compose the grillage; though, the user can easily make it more versatile using…

In RM Bridge at the Modeler component the Axie elements usually represent the Axis of a road alignment; but, in more geometrically complex models, an Axis could also be the transversal support lines or any other local reference axis that is needed. One…

Stress leading results require some additional definitions in RM Bridge : As stresses are in general a post-processing calculation using internal forces or strains the cross-section has some Reference Sets where these reference points are created and…

Modeler is the modeling tool part of RM Bridge Enterprise CONNECT Edition , where users can start a project or make geometrical modifications to existing models. As a bridge-specific tool, for input, it usually takes the alignment or the local Axes…

Tables an d Formulas together with Parts and Variables are a powerful parametric modeling tool in RM Bridge CONNECT Edition : to efficiently model different Cross-Section and Elements shapes. They allow for modifying Elements by changing their Cross-Sections…

Within RM Bridge CONNECT Edition , inside Modeler, at each Segment, Variables can be assigned to Formulas and those can be defined by Expressions and Tables that can use alignment station-dependent functions. The construction of expressions using tables…
