Respected SIr,
I had a doubt that a have bridge deck which is resisting on four longitudinal girders and three cross girders. Length of cross girder is 11.50 m and that of longitudinal girder is 30m. The depth of slab is 240 mm and that of longitudinal beam is 2m. So is the slab spanning in one way or two way? Slab is simply supported on all four longitudinal girders on both sides.
I want to model slab as plate element for various load cases,what boundary conditions I should take?
Please give me guidance about this.
