(TU Delft Steel & Composite Structures; Universidad San Francisco de Quito) Contributor Zingoni, Alphose (editor) Date 2016 Abstract A large number of existing bridges in Europe and North-America are reaching the end of their devised service life. Therefore, it is necessary to improve the methods of assessment for existing bridges. One method, suitable for existing reinforced concrete slab bridges, is the Modified Bond Model. This method, however, currently only takes the effect of torsion for loads close to the edge into account in a simplified manner. In this study, finite element models are created of a slabs with two supports, three concentrated (pre-stressing) loads and a distributed load, representing a truck wheel print. The load is varied along the longitu-dinal and transverse directions of the slab to find the bending moments (mx and my) and torsional moments (mxy). The results is an expression for the effect of torsion in slabs, which can be used with the Modified Bond Model for assessment and design of slab bridges To reference this document use: http://resolver.tudelft.nl/uuid:47983062-d974-4365-889f-b49707b5bffc Publisher CRC Press ISBN 978-1-13-802927-9 Source Insights and Innovations in Structural Engineering, Mechanics and Computation: Proceedings of the 6th International Conference on Structural Engineering, Mechanics and Computation, Cape Town, South Africa, 5-7 September 2016 Event 6th International Conference on Structural Engineering, Mechanics and Computation, 2016-09-05 → 2016-09-07, Cape Town, South Africa Part of collection Institutional Repository Document type conference paper Rights © 2016 D.A.
