CORRELATION OF THEORETICAL AND EXPERIMENTAL DATA FOR HIGHWAY BRIDGES. VOLUME I. STATIC LOADING
A computer program analytical routine 'SSAP2' is used to correlate a theoretical finite element analysis with experimental response of four typical two-lane multi-span girder and slab highway bridges in Tennessee. All bridges give excellent correlation between predicted and experimental responses for deflection and moment distribution to the girders, when the stringers are modelled with beam elements slave connected to plate-shell elements for the deck. The aspect ratio of element modelling is a critical factor for the finite element analysis. It is concluded that reasonable analytical results can be obtained with the SSAP2 program for non-skew straight composite beam bridges and skew composite beam bridges for low skew angles (less than 30 degrees) provided all element aspect ratios are limited to 1.5 or less. A further restriction in the use of the SSAP2 program is that the bridge load deflection response must be in the linear range.
