Self-weight-induced stresses

To minimize the self-weight-induced stresses, innovative deck cross-sections with high sectional (bending and shear) efficiencies coupled with innovative materials have to be invented A few such cross-sectional shapes of FRP composite decking were successfully implemented by various State Departments of Transportation in the United States. The decking systems are shown in Fig. 31.3, with cost comparisons in Table 31.1.
