Webinar: Parametric Tendon Modeling

Author: Željka Devedžić - Company: ALLPLAN Infrastructure GmbH - Date: February 15th, 2021

Allplan Bridge is a powerful solution for the parametric modeling, structural analysis, reinforcement design and detailing of bridges in 4D. The software supports all design phases, from the concept to the final design. Due to the high level of detail, the geometrical and analytical model are ideal for visual design and coordination. Allplan Bridge makes all this possible - easier, faster and more precise than ever before.


There are many different types of pre-stressing and a variety of tendon geometries. Allplan Bridge provides several workflows of modeling the tendon geometry and makes it easy to model a wide range of pre-stressing types.

In general, there are two main modelling approaches: defining 3D tendon points or defining 3D tendon tangent directions. In both cases the program automatically generates the geometry of a tendon along the bridge structure.
