Bridges consisting of multiple parallel pre-stressed and pre-fabricated Tee-beams topped by a cast-on-site concrete slab are often a cost-effective way of constructing simply-supported and multi-span bridge structures in many countries world-wide. For the design of these bridges computer models are often utilised. This thesis presents a comprehensive discussion of modelling issues encountered in the practical design work on this bridge type. A chapter on the modelling of various loading conditions is followed by a detailed discussion of the modelling of the longitudinal load bearing system, the Tee-beams, and the lateral load-bearing system, the roadway slab. A summary of commonly used bridge systems in various countries is also included. All this material is presented considering design code requirements in various internationally used specifications. The information included in this thesis has been used to define specifications for the implementation of a software tool to support the design of so-called Super-Tee bridges. A summary of these specifications is given in the conclusions of this thesis. Material included in this thesis has also been published in the following conference proceedings: Pircher G., Pircher M.
