Free Trial Bridge Workflow

DO YOU CONSTANTLY STRUGGLE WITH THE FOLLOWING CHALLENGES?

Inconsistent design data from different data sources and formats from different parties involved.

Numerous time-consuming design modifications lead to inconsistencies and poor design quality.

Due to lack of time, bridge designers can't create as many design variants as they would need to find the best solution.

Constantly re-entering the same data over and over again in your projects taking up your design time.

HOW ALLPLAN BENEFITS YOUR BUSINESS

because everything is accomplished with one software solution – the common data environment minimizes unnecessary data exchange and re-entry between different solutions.

 

time saving through adaption of project templates and model modifications that occur throughout the entire design phase that are made quickly, easily and reliably.

precise modeling due to modeling techniques which are tailored for bridges and workflows for different bridge types, such as precast girder bridges.

reuse of data as a result of the parametric model description - modeled bridge elements, e.g. a pier, can be saved as template and reused in subsequent projects.

Work with a single solution from parametric model creation with a high level of detail, including prestressing, to integration of the construction process and structural analysis of the bridge model, including reinforcement design and code checking.

The 3D parametric model description considers the road layout, bridge alignment and required cross-sections, making model configuration and variation fast and easy. This can be done either directly in the software or even via scripting.

Allplan Bridge automatically generates the analysis model from the geometrical model and all the calculation actions from the defined construction sequence. This greatly reduces the amount of work and susceptibility to errors.

All permanent and variable loads are combined between each other into a final envelope. This envelope is used to perform reinforcement design and code checking.

The entire 4D model adjusts in the event of any change, such as in relation to the alignment. Hence, if the geometry of an axis changes, the entire bridge model is adjusted automatically.

From initial plans through to materials, quantities, and final general arrangement and reinforcement drawings, quality and accuracy to rely on.

2 \ MODELING & PRESTRESSING
Parametric Bridge Oriented Modeling

All types of bridges, whether complex or simple, can be modeled with Allplan Bridge. This is possible due to its principal modeling method - the 3D parametric model description considers the road layout, bridge alignment and required cross-sections. It is tailored for bridges with a geometry that is directly governed by the axis. It also allows modeling of complex geometries, including double curved alignment, and variable cross-sections.

Customized Modeling for Precast Girder Bridges

Precast girder bridges have one thing in common – their component geometry. The straight profile of precast girders is why their geometry is not directly impacted by the road or bridge axis. That is why Allplan Bridge provides special features and a specialized workflow. The reuse of girder shapes and lengths is a further typical feature of precast girder bridges and in Allplan Bridge “modular modeling” addresses this whilst providing an efficient workflow.

Free Parametric Modeling

The third modelling technique available in Allplan Bridge allows the user to parametrically model the entire bridge or its sub elements freely in 3D space using volumetric primitives and Boolean operations. In the first release of this new technology for volumetric primitives advanced prisms are implemented - the basic shape of a prism is defined using the well-known cross-section definition. Because this is rather a more general parametric modeling technique, it can be used for parametric modeling of other infrastructure requirements as well.

Placement of Detailing Objects

Parametric objects from the Allplan library, can be referenced in Allplan Bridge to add further details such as reinforcement, anchor devices of tendons or lamp posts to the bridge model. To do this, reference points are defined and linked to the object in the Allplan library using the respective name. When the parametric model is transferred to Allplan, the corresponding objects are positioned and adjusted whenever the model is updated.

3 \ STRUCTURAL ANALYSIS
Derivation of Analytical Model

After creating the BIM bridge model, you can perform the structural analysis of the bridge directly in Allplan Bridge. The analysis model is automatically derived from the geometrical model which is complemented with all the analysis relevant definitions. This process is completely user controlled and greatly reduces the amount of work and susceptibility to errors.

Construction Sequence Calculation

The BIM model in Allplan Bridge contains also the 4th dimension – time – which is considered when specifying the construction process. To perform construction sequence analysis, the product analyzes the previously defined construction schedule and assembles all necessary calculation definitions in an automated process, such as self-weight load cases, element activation and calculation actions. This includes input data for calculating nonlinear time effects, creep, shrinkage and relaxation. All the generated items are listed in “logging” and with that complete transparency is enabled.

Time Dependent Analysis

Particularly important for the construction stage analysis of prestressed and reinforced concrete structures is the correct consideration of the time-dependent effects. In Allplan Bridge the calculation of creep and shrinkage of concrete and relaxation of prestressing steel is code-compliant and available according to several standards, including EN and AASHTO.

Permanent and Variable Loads

The weight and the position of superimposed dead loads (like sidewalk, road pavement, etc.) are automatically retrieved from the geometrical model. Additional loads, like temperature change (including nonlinear temperature distribution), wind loads, settlement, loads due to braking and acceleration, etc. can be defined and applied easily as well.

Traffic Loads

The definition of the traffic load is split into 2 steps – automatic or manual definition of notional lanes and load trains (moving loads). The moving load calculation is based on the theory of (related) influence lines allowing an easy and swift calculation. First the influence lines are calculated and then the evaluation of influence lines is performed and the results are saved into an envelope.

Dynamic Analysis

Allplan Bridge uses the multi-mode Response Spectrum Method for evaluating the effects of seismic loading. Mathematically, this solution is based on the excitation of the relevant natural modes and combining the different modal contributions. Internal force and displacement amplitudes related to the individual natural modes are superimposed using different methods, such as the Complete Quadratic Combination (CQC) to obtain the envelope of extreme values.

Superposition and Combinations

The user-friendliness and usability of the superposition in Allplan Bridge is groundbreaking. The schematic definition of the superposition combines maximum flexibility and optimal overview. The same applies for the combinations, which are defined and visualized in a table form, giving the user optimal overview of different combination types and load factors. Furthermore, it is possible to select several stress components in user-defined stress points and perform a stress leading superposition.

Bridge Design

Altglienicker Bridge

Berlin, Germany

The unique arch shape between the pavement and the road enables optimal load transfer with the smallest possible dimensions. A low construction height is achieved via a small cross-girder span, which, on the one hand, overcomes the narrow conditions in the watercourse area, and on the other hand, uses less material. A lateral arch overhang – which absorbs the transverse bending and provides stability – can also be used as a lighting strip. structure.
