RM2006 (c) TDV

Modelling of 3D structures using a CAD like pre-processor including definition of project axis in plan and elevation.
The 3D structure is analysed allowing the simulation of any erection procedure linking the erection with to the time axis in the calculation (4D).
There are no limitations regarding bridge type and erection sequence.
14 international design code are currently incorporated and the program carries out specific SLS and ULS design code checks in accordance with these standards.
The program is in use by many international consultants and a few thousand bridges worldwide have been designed using this powerful engineering tool.

The following practical applications are specifically supported by the program:
Classical composite structure
Steel girder and concrete slab – the “classical” composite structure problem.
Different types
Different types of concrete (quality or age) combined in one single cross section, e.g. pre-cast (pre-stressed) beam and cast-in-place-slab.
Additional module
The following functions are available in this additional module:
Cross sectional characteristics
Integration of the individual parts of the total composite section. The cross sectional characteristics of the composite section are computed automatically by using the given values of the individual parts and taking their relative geometric positions into account.
The results are related either to the individual section parts, or to the integrated composite section, depending on the situation in the different calculation processes.
In every case the program will derive the individual results for each section part and will decompose the value for the composite section into the individual parts. All post processing functions (design code checks, graphics, etc.) can therefore be performed for the individual section parts as well as for the composite sections.
Pre-stressing, creep and shrinkage
Each part of this cross section can be individually identified for pre-stressing, creep and shrinkage. The user specifies the appropriate coefficients according to the individual age of concrete and the time step.
The calculation of time dependent displacements and internal forces – for individual parts as well as for composite sections – is carried out by using the same algorithm as described in the pre-stressed concrete structures technical description.
Construction stages
Generally the same features for construction stages are available as those described in the pre-stressed concrete structures technical description. An additional feature in this module makes it possible to activate an individual part of the composite section in a single construction stage. This allows not only the changing of the structural system, but also of the cross section during the construction stage sequence.
Each part of the section may be individually pre-tensioned or post-tensioned. All pre-tensioning and post-tensioning functions can be used and are described in detail in the technical description for “pre-stressed concrete analysis”.
Shear connectors
As a unique a feature RM2006 contains a specific element type allowing the design of this structural part as well. The shear connector element is activated automatically when a composite cross section is completed. All results (loading cases as well as envelopes from superposition files) are available for these elements as well (only normal force is of interest!)
