By using a beam model that accounts for interface shear connection deformability and slab loss of planarity (shear-lag), the long term behaviour of composite continuous two-beam decks with high performance concrete slab is analysed. The main actions usually considered in composite bridge decks design, namely static and geometrical actions and slab shrinkage, are separately analysed by determining, for each, the effective slab width, that describes the shear-lag effect on the cross section and its time evolution.

Abstract

By using a beam model that accounts for interface shear connection deformability and slab loss of planarity (shear-lag), the long term behaviour of composite continuous two-beam decks with high performance concrete slab is analysed. The main actions usually considered in composite bridge decks design, namely static and geometrical actions and slab shrinkage, are separately analysed by determining, for each, the effective slab width, that describes the shear-lag effect on the cross section and its time evolution.
