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…

OBD CE 2022 Release 1 and RM Bridge v11.14, the User can import OBM Deck Templates into RM Bridge for structural analysis, following the below steps: 1.OBM Create Deck Template In OBM > Utilities > Libraries > Decks, create a new deck cross-section…

At the Recalc Window: 3. Dynamics/Iterations: 2. Iteration control , the definition of the convergence parameters for non-linear iterative structural deformation analysis is set. The default values ensure in general a fast and sure convergence to an extremely…

RM Bridge Enterprise Recalculation Window has, inside the Advanced Options, the possible Dynamics / Iterations options to be set up; and, as shown in the screenshot below, they settings 2. Iteration Control , includes an option Used processors (threads…

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…

The Recalc Window 2. Extended Settings: 2. Pre-stressing allows the users to set additional definitions for the calculations related to the stressing of tendons: Update CS Values: (-) duct areas : The area of the ducts is excluded in a new cross-section…

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…

For RM Bridge inside OpenBridge Designer users have the option to Read Cross Section From DGN at Modeler\Import CS that allows the DGN drawing files to be used to create just the references, as no intelligence or references or variables are yet possible…

The Recal Window 2. Extended Settings: 1. Special Settings allow the user to create additional definitions of: Use Shear Lag Defs for Stiffness reduct .: Shear Lag areas are ignored for bending moments of inertia reducing the CS values. Join Primary…

The Recalc Window Menu Options 2. Extended Settings allow users to set additional global calculation parameters for: Special Settings : Shear Lag and deformation, Composite Join Forces, Primary TempVar, FE results options; Prestressing : Cross-section…

In this Demo example a simple-supported beam with three different prestressing is considered for comparison: Variant 1 - PExt: External Tendons Only Variant 2 - DEFAULT: External and Internal Tendon Variant 3 - PInt: Internal Tendons Only …
