Stiffness analysis of interconnected T beam bridge systems by digital computer

Load distribution in t beam bridge systems not only occurs by flexural action but is also influenced by the fact that the slabs transfer induced direct forces. An attempt was made to assess the extent of this influence. Because of its wide practical application the guyon massonnet theory for t beam systems was used to compare the results of the present analysis. By employing stiffness coefficients and matrix notation the problem was programmed for and processed by the bendix g.15 Computer. Junction displacements were first determined and thence the lateral distribution of deflection and lower flange stresses were obtained. For the immediate automatic computing, the transverse position of the load, the guyon massonnet parameters and a term introduced to define the t beam action were selected for investigation. The validity of the theory was tested by analysing a 5 girder model for which experimental results were available. Further comparisons were made by analysing an example for which an alternative theoretical solution existed (A).
