- Abstract
Tests on a perspex model of a very wide slab and beam bridge system continuous over two spans are described. The observed behaviour is compared with that predicted by an analysis using the guyon massonnet method where the system is regarded as an equivalent orthotropic plate. It is shown that the general behaviour, as represented by the overall deflected shape, agrees well with the theoretical predictions. However, more localized effects, as represented by strains and shear forces do not always show so good an agreement. It is found that a concentrated load applied between diaphragms may produce bending stresses in the beams more than double those predicted from the orthotropic plate theoretical analysis. Such effects can become significant when abnormal concentrated loads are a major design consideration (A).
