A method based on orthotropic plate theory is presented to determine the distribution of lateral loads in multibeam concrete bridges that have low transverse flexural rigidity or are torsionally stiff, and thus are outside the range of the Guyon-Massonnet approach.The deflection, bending and torsional moments, shearing and reactice forces are expressed as functions of dimensionless distribution coefficients.
