“While 2D drawings are good for easy construction, with a 3D model the design is much more precise – there are no collisions between structural members or reinforcement, and it is much easier to visualize the complex details. Here, the concrete reinforcement could be easily modeled, the documentation such as general arrangement drawings created, and visualizations of the completed bridge generated.įor the designers at Sagasta, 3D bridge design using Allplan Bridge offers a number of compelling advantages.
#ALLPLAN BRIDGE 2021 UPDATE#
Changes of the span length or other variables were quick and easy to do in Excel and then update in Allplan Bridge, with linked variables updating automatically.Īfter the bridge design was completed, the bridge model was exported into Allplan Engineering for completion. The designers used a text file with the correct stationing, which was originally created in Microsoft Excel and then copied into Allplan Bridge.

This was done automatically by the software, but the stationing would then need to be updated as well. Every time the road alignment was updated, the bridge needed to be moved to the correct position. The road alignment was changed several times, as well as the design of the initial four different variants. The benefits of parametric bridge design include more than just updating the cross-section.

This way, the cross-section could be adjusted as required and the linked variables would also update, saving valuable design time and reducing the risk of errors. Designing it parametrically enabled variables to be included, such as the distance of the beam to the road axis, the beam height and width, the height of the precast slab, and the height and angle of the roadway. Creating this cross-section was as simple as creating one parametric cross-section of one of the steel beams, and then replicating it for the other five beams. The main span uses six steel beams to support the lower concrete slab. This way, the cross-sections could be designed and adjusted easily and then the road and bridge structure could be swiftly designed by extruding the cross-section along the alignment. For each variable, longitudinal profile stations were assigned which linked to the vertical alignment of the bridge. This made designing the cross-sections much easier, as each parametric cross-section had variables assigned such as length or angle. Parametric design was used due to the large number of structural members involved. From this base, the rest of the bridge – including the bridge structure, road, cornices, safety barrier, piers, and retaining walls – were all designed parametrically in 3D using Allplan Bridge. xml format, giving the bridge engineers the data they needed for their design. The horizontal and vertical alignments of the bridge were then imported into Allplan Bridge in. Several different road alignments were designed to determine the best option of the new overpass. This unusual construction method and composite design ensured that no formwork was required over the railway during construction, reducing the disruption to the operation of the railway.ģD Bridge Modeling Using Parametric Design The central span that crosses over the railway includes a precast concrete slab supported by steel beams, which acts as the formwork for a cast in-situ reinforced concrete slab on top. The main span is supported by piers, while the rest of the bridge sections are each supported by two bearings. The new bridge was designed using prestressed concrete slabs for the bridge spans, which vary in length from 15m to 27.5m. engineering consultants, is one of their first projects designed entirely in 3D using Allplan Bridge and exploits the benefits of parametric bridge design. The bridge, which was designed by Sagasta s.r.o. The new seven-span bridge will have a total length of nearly 145m, with a 27.5m span over the railway. Not only will this enable the separation of the road and railway traffic, but the existing road alignment could be improved at the same time to provide a safer and more comfortable ride. In Kynšperk nad Ohří in the Czech Republic, a new bridge will soon replace the existing level crossing.
