Tendon Manager#
Introduction#
Welcome to the SOFiPLUS Modelling Tutorial.
This tutorial focuses on the Tendon Manager feature in SOFiPLUS prestressing tab. The feature enables a quick and efficient overview of a prestressed system in SOFiPLUS. It allows us to graphically control tendons and tendon geometry and modify the properties of multiple tendon elements at the same time.

Project Description#
The tutorial example is a 330-meter-long reinforced concrete arch bridge, featuring a superstructure composed of two prestressed girders.
The bridge includes a 180-meter-span reinforced concrete arch with a rise of 55 meters. The arch has a box cross-section, designed as a double-cell structure with a constant depth. The superstructure spans continuously across 11 spans of 30 meters each, consisting of two prestressed girders.
The bridge piers, with an elliptical cross-section, range in height from 6 to 64 meters.
Note
This is not a practice relevant example. It is intended to demonstrate the described feature.
Control the Tendons#
As a first step, the properties of the tendons are checked in a table. Additionally, the position of the tendons is verified in a 3D overview as well as in a 2D cross-sectional view.
Modify the Tendons#
In the second step, the properties of the tendons are modified in the table. This is demonstrated using the name of a tendon geometry and the construction stages of several tendons.
