Abstract:
Two methods are presented to analyse the irregular shaped slabs and pseudo-slabs. The finite element method based on grillage analogy is programmed, in which the effects of shear deformation are taken into account, and the concept of isoparametric element is introduced to load distribution for quadrilateral grid. The formulas based on grillage model are developed to calculate the influence surface, and the corresponding program is designed. For the convenience of application, the influence surface is automatically given in the form of coutour line, which offers a new way for the design of irregular shaped bridges. The photoelastic coat test results of forked bridge model are in agreement with those by the program. Finally, an example is given.
