On a numerical technique of all fixed slab with multi layers

Stress and displacement generated near a loading point on a multi layer slab have been conventionally estimated from deflection and stress resultant derived from the thin plate theory. To understand the behavior of the slab precisely on a local basis, a three-dimensional analysis is required. This s...

Summary:Stress and displacement generated near a loading point on a multi layer slab have been conventionally estimated from deflection and stress resultant derived from the thin plate theory. To understand the behavior of the slab precisely on a local basis, a three-dimensional analysis is required. This study proposes a method to create clamping conditions approximately through harmonic analysis by placing dummy girders with high flexural rigidity at locations very close to simply-supported edges. A technique that is combined with the point matching method was developed and applied to the calculation of stress and displacement generated near the loading points and on the layer boundaries of a multi-layer slab with all edges clamped. This technique allows description of three-dimensional stress and displacement properties within the slab except near the dummy girders.
