Summary
:
A capacity control (ULS) has been carried out in both the bridge superstructure and the columns for both for the original design loads and for additional loads from Alkali-Silica Reactions. The original loads and load factors are according to Handbook R412 ”Bridge Classification”. The load actions from Alkali-Silica Reactions are based on ”Alkali Silica Reactions - Guidelines for Constructive Analysis”, issued by the Directorate of Public Roads. The capacity control are performed according to the Norwegian Standard, NS 3473: ”Design of concrete structures”. Two computing programs have been used in this thesis, Abaqus CAE and Robot. Robot is a frame program that is used to find the design loads from the ordinary loads on the bridge, as well as the external loads actions from Alkali-Silica Reactions. Abaqus is a finite element program that is used to calculate the effect of the expansion from the Alkali Silica Reactions in several directions.
