Support Deflection Effects in Slabs with Beam and Girder

보-거더 시스템 슬래브에서 지지부 처짐영향에 관한 연구

The support deflection effects in slabs with beams and girders are reviewed for both cases of the uniformly distributed and concentrated wheel loads. The differences in structural behavior according to the variation of support stiffness namely, the moment of inertia of beam and gilder, and the slab thickness, are calculated using the finite element method. Besides. the correction factors which can consider the support deflection effects in slab design are proposed by regression based on the obtained numerical results. Through the comparision studies of slabs with different boundary conditions, the importance for the consideration of support deflection effects in design are emphasized.
