Abstract
Some laminate orientations have decreasing values of $\small{D_{16}}$, $\small{B_{16}}$, $\small{D_{26}}$ and $\small{B_{26}}$ stiffnesses as the ply number increases. For such plates, the fiber orientations given above behave as specially orthotropic plates and simple formulas developed by the senior author. Most of the bridge and building slabs on girders have large aspect ratios. For such cases further simplification is possible by neglecting the effect of the longitudinal moment terms(Mx) on the relevant partial differential equations of equilibrium. In this paper, the result of the study on the subject problem is presented.
