Numerical analysis of in-situ stitches in prestressed concrete segmental bridges

Session - Structural EngineeringPrestressed concrete segmental bridges are widely used as they can easily adapt to various site conditions. The in-situ concrete stitches in the construction of these bridges are subject to complicated stress conditions and they are therefore potential weak points in the structure. However relatively little work has been done in this regard. This paper describes the finite element analysis of mechanical behaviour of in-situ stitches by using the package Midas FEA and the results …published_or_final_versionThe 2nd International Postgraduate Conference on Infrastructure and Environment (IPC2010), Hong Kong, China, 1-2 June 2010.
