Welcome to example of prestressing concrete bridges. This example is free released to project students at DTU Ballerup Campus by ICDAS.
Technical University of Denmark ♦ DTU Ballerup Campus Exam project 2015/2016 ♦ Answer Book & Case Study Motorway Bridge over Savstrup Stream in Jutland Denmark Terrain - Geometry - Analysis 1 , 2 , 3
Exam Project at DTU Ballerup Campus is consisting of two parts, a project suggestion and a main project. The main project in this case is a motorway bridge carrying Load Model 1 (LM1) and the UDL. The bridge is constructed with concrete, prestressing cables and mild reinforcement. Verification of concrete, prestressing cables and mild reinforcement are according to Eurocode and Danish
Road Directorate April 2015. Refer to ICDAS Design Basis for design criteria in ULS and SLS load
combinations.
This answer book describes short software tools for creation of bridges, and the bridge itself as well. There are three models needed for a bridge project: Terrain model (AutoCAD Civil 3D) Geometry model (Revit Bridge) Analysis model (LUSAS Bridge) The terrain model determines position of the bridge in lands coordinate from which man build the bridge
corridor. In geometry model man design the lengths of span, deck type, bearings, piers, abutments and
the foundations. In analysis model man divide the geometry model into small elements to perform an
analysis, also known as Finite Element Method (FEM model).
