RAISE YOUR LEVEL AND BRIDGE SMARTER
Allplan Bridge is a powerful solution for parametric modeling of bridges. The software supports all design phases, from concept to final design.
Design your bridges more efficiently:
- Optimal work processes for bridge design
- Maximum flexibility and reduction in errors due to design modifications
- Improved BIM workflows
- Easy optimization of bridge geometry
- Precise and reliable
Model creation without compromise
Allplan Bridge has been to the requirements of bridge engineers. The 3D parametric model description considers the road layout, bridge alignment and required cross-sections, making model configuration quick and efficient. Complex geometries including double curved alignment and variable cross-sections can be created easily with the help of alphanumeric entries and formulas.
For example, the user only needs to define one typical cross-section and Allplan Bridge will accurately calculate all cross-section variants in accordance with the defined table(s) or/and formula(s). A complete 3D Bridge model cannot be generated more easily or quickly.
Prestressing made simple but not simplified
Pre-tensioning, post-tensioning, internal and external tendons, transversal and vertical tendons, and other non-standard tendon geometries can be easily modeled in Allplan Bridge. The geometry of a tendon is automatically generated based on user defined 3D points along the bridge structure. Each 3D tendon point is specified by the station and the position in cross-section related to certain reference point. Plan and elevation angle and radius can be specified as additional constraints. Certain parameters can be set to free. That means that the value will be optimized in accordance with the condition that the tendon losses are minimized.
To define the in-plane position of the tendon a special point raster is available in the cross-section. It allows not only an easer tendon definition but enables copying and mirroring the tendon(s) in the longitudinal and transversal direction.
Changes made in no time at all
Allplan Bridge helps you to manage the inevitable changes that occur during the design process. The parametric model description is an ideal base for adapting design changes. The modifications are incorporated only at their origin and all other linked members are automatically updated. For example, if the road axis changes the complete bridge geometry will be adjusted. If only a certain structural member is modified only directly linked elements will be recalculated.
Not only objects in Allplan Bridge but also elements from Allplan (Engineering) library can be referenced in Allplan Bridge and are together representing a detailed parametrical bridge model.
Smooth data exchange
Integrating road data used for road/bridge alignment is easily achieved via ALLPLAN’s open BIM platform Allplan Bimplus. The bridge engineer must only take over the road data and can immediately start with the bridge design. To assist the engineer even further, the bridge model can easily be transferred to analysis software (such as Bentley RM Bridge) for structural calculations. Once the design is completed, the parametric model can be transferred in Allplan Engineering for completion of pre-stressing and reinforcement drawings.
Compared to mechanical engineering CAD software or traditional 2D drafting, working with Allplan Bridge is very convenient and specifically tailored to the requirements of bridge engineering. This leads to an essential optimization of the working speed. Furthermore, you can use Allplan Bridge on multiple monitors at the same time. Allplan Bridge automatically adapts its user interface to the screen size and resolution and is ideal for the use in powerful high-resolution monitors (4D/UHD with 3840×2160 pixels and more).
Allplan Bridge benefits from a built-in database that is continuously logging modifications as the project progresses. This will benefit projects that have a long design period by ensuring project data is securely available for the duration of the project.
From model to time planning
The parametric bridge model generated in Allplan Bridge can be subdivided into individual construction elements. These can be transferred to Allplan Bimplus and linked with time-specific attributes. Thus a construction sequence can be easily defined and visualized.
Stressing sequence for pre-stressing tendons
For each parametrically described tendon a stressing sequence can be defined.
There are three different actions, Stressing, Wedge Slip and Releasing. All these actions can be defined at the begin and at the end of a tendon. Furthermore, it is also possible to define all these actions at both sides of the tendon simultaneously. The result is in this case different as if the actions are defined subsequently.
The input is group oriented allowing to optimize the management of the tendon stressing procedure. The actions described above, are defined only for the user defined group(s). With the drag-and-drop functionality the tendon(s) is(are) assigned to the corresponding group and are automatically stressed as it is defined for the group. To allow more flexibility, values can be adjusted for each tendon individually.
