Static Behavior of Noncomposite Concrete Bridge Decks under Concentrated Loads

Abstract

Tests were conducted under a concentrated monotonically increasing static wheel load on 1/6.6-scale physical models of three different types of noncomposite deck structure: (1) the entire deck supported on four steel girders; (2) an isolated deck slab region with a width equal to 1/3 of the bridge span; and (3) a 102-mm-wide transverse “beam” deck strip, both simply supported on two opposite edges on adjacent girders. Three reinforcing arrangements for the noncomposite concrete deck are studied: (1) orthotropic steel reinforcement (AASHTO); (2) isotropic steel reinforcement (
