OUR WORKFLOWS

Doing the right thing

null

In Allplan Bridge, you can adopt the data from an existing design (using LandXML data format) or define it manually.

null

You can define any cross-section and determine the geometry with its dependencies and variables. These parametric cross-sections can be adapted at any time and be saved as a template and be reused.

null

Standardized and repetitive profiles such as longitudinal stiffeners for steel and composite cross-sections can be easily positioned parametrically.

null

The digital model In Allplan Bridge is completely parametric. Changes can be made at any time. The dependent objects are automatically adjusted. Allplan Bridge is suitable for all phases of work – from the concept to the detailed design.

null

Allplan Bridge makes it easy to modeMoreide range of types of pre-stressing: with immediate or later bond, internal and external, longitudinal, transverse and vertical, as well as with non-standard geometry.

null

A stressing sequence can be defined for each tendon specified in the model.

null

Time as the 4th dimension is considered by easily specifying the construction process. The construction plan is divided into several phases and further into individual tasks. The related structural components are interactively assigned to these tasks.

null

Thanks to breakthrough technology, Allplan Bridge automatically generates the analysis model from the geometrical model. This greatly reduces the amount of work and the susceptibility to errors.

null

Allplan Bridge analyses the defined construction schedule and sets up all necessary calculation definitions in an automated process, like load cases, element activations and calculation actions.

null

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 or wind loads, can be defined and applied easily as well.

null

Traffic loads can be defined and applied in a very comfortable way. On the one side, traffic loads can be applied automatically according to the selected standard. On the other side, the generic approach to defining live loads in Allplan Bridge allows to take any type of moving load into account.

null

With Allplan Bridge, the most unfavorable effects due to traffic loads can be determined quickly and easily using the theory of (related) influence lines

null

The user-friendliness of the superposition in Allplan Bridge is groundbreaking. The schematic definition of the superposition combines maximum flexibility with optimal overview.

null

A global static analysis based on the Bernoulli beam theory is performed for all automatically and manually generated calculation actions defined previously in the construction sequence definition.

null

After the global effects have been calculated and the corresponding envelopes generated, the user can perform the code-dependent design to determine the required reinforcement area

null

Objects from the Allplan Engineering library can be referenced in Allplan Bridge to add further details such as lamp posts or anchor devices of tendons to the bridge model.

null

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 for geometrical and analytical model.

null

Powerful 3D modeling functionality allows to implement all bridge details without compromise: simply, flexible, and with the highest level of precision. The Parasolid® modeling kernel from Siemens handles intricate free-form geometry based on B-Splines and NURBS as well as for standard tasks such as joints, cut-outs and drainage with ease.

null

With Allplan, even challenging bridges with double curvature and varying
cross-sections are reinforced conveniently and rapidly. The reinforcement is defined in different cross-sections and the transitions between the cross-
sections are described with paths. Various rules can be defined, such as how
the reinforcement joints are to be carried out. Using this information, the reinforcement is automatically generated.

null

Elevations, longitudinal sections along any path and transverse sections are derived from the digital bridge model. CineRender from Maxon is used for realistic visualizations. Allplan’s powerful layout and design tools are used to create high-quality construction documentation.

null

The digital bridge model containMoreultitude of information. Comprehensive reports with dimensions, areas, volumes, weights and quantities are available at the touch oMoreutton. This also applies to rebar bending schedules.

null

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. Once the design is completed, the parametric model can be transferred in Allplan Engineering and to analysis software.

null

The analytical model generated in Allplan Bridge can be shared with other analysis solutions by uploading it to the cloud-based BIM platform Allplan Bimplus.

null

With the combination of Allplan and the cloud-based BIM platform Allplan Bimplus, everyone involved has access to the latest design, anytime, anywhere and with any device. BIM coordination happens interactively on the digital bridge model. Discrepancies are detected at an early stage and resolved jointly. This is an important contribution to ensuring that the construction project is completed on time and within budget.
