Integral abutment bridges are becoming rather common, due to the durability problems of bearings and expansion joints. At the same time, among short- and medium-span bridges, multi-beam steel-concrete composite deck with hot-rolled
River bridges (KCSB) are steel/concrete composite deck slab bridges developed by JFE Engineering. Combining the advantages of steel and concrete, they can be constructed to a low structural height that could never be realized with steel
for the design of the shear connection in steel–concrete composite bridges with precast decks, design considerations were discussed, and experimental works on the push tests and the bridge model test were performed. The characteristics of
17 Nov 2012 This module provides practical information regarding the decking options and design considerations for steel bridges, presenting deck types such as concrete deck slabs, metal grid decks, orthotropic steel decks, wood decks,
What made Defiance County look at this Problem. ? 4 – 100+ year old pin trusses on stone roads. ? Narrow roads, narrow RWs, trusses in good shape but very light. ? Previous County Engineers kicked can down the road. ? Load Rating gave us
Abstract. Hybrid structures are structural systems constituted of elements assembled with different construction materials. This work addresses the particular case of bridges decks, which, due to constructive and/or economical constraints, have
This note discusses the use of the steel-free concrete bridge deck technology in continuous span bridge structures. Conventional slab-on-girder design often utilizes the longitudinal steel reinforcement in the deck to resist the negative bending
18 Oct 2017 Abstract. An innovative steel and concrete composite bridge deck slab using bent bars and epoxy as shear connectors was proposed. Four slab specimens with different types of concrete were fabricated and tested to study
Abstract. This paper examines the structural efficiency of fibre reinforced polymer (FRP) decks for replacing traditional concrete decks intended for bridge upgrading. The investigation, which is performed by means of finite element analysis,
Abstract. A comprehensive research investigation was conducted to evaluate the use of Stay-in-Place Metal forms. (SIPMFs) in construction of concrete bridge decks. The objectives of this research project were to establish the.
This paper introduces a steel-concrete composite bridge deck with perfobond rib shear connectors designed for the prestressed concrete I-girder bridges. The composite deck consists of profiled steel
The Millau Viaduct a cable-stayed bridge of Millau, France has the largest orthotropic steel deck to refit a bridge originally designed with a concrete or non-structural deck to use an orthotropic deck,
7 Aug 2017 steel–concrete hybrid bridge decks have been used in several bridges for their added benefit in constructive operations and cost. They usually adopt reinforced concrete side-spans and all-steel or steel–concrete composite
15 Sep 2017 ABSTRACT. Composite bridges, where steel girders are used compositely with a concrete deck slab, can be preferred over steel or concrete bridges due several reasons. They are less expensive and require.
Structural performance of steel-concrete composite deck for steel-box girder bridges. Authors The main objective of this study is to develop a longspan composite deck that weighs, less than the conventional cast-in-place concrete deck.
Panel Bridge? is composed of a steel-concrete composite deck, steel I-beam, and SRC cross beam. The characteristics of the bridge–aside from having a maximum span length of 40 meters–are as follows. (1) It can be applied to short span
This paper presents a study on the effectiveness of various casting techniques used to control slab tensile stresses during the construction of continuous steel-concrete composite bridge decks. The main features describing the early age
9 Jul 2013 State DOTs have expressed a need for corrosion-resistant, light-weight bridge decking for rapid installation on bridges. FHWA's Highways for LIFE Program dem

This paper presents an experimental study of a steel–concrete composite bridge deck slab with profiled sheeting and perfobond shear connectors. Two full-scale deck slab specimens cast onto three concrete blocks were fabricated and tested
A study focusing on optimization and efficiency of relatively common solution for small span railway bridges is presented. The superstructure of the bridges is created by reinforced concrete deck with encased steel beams. Especially, flexural
Full depth precast deck slabs are one of the most common prefabricated deck systems. With this decking system, the deck is poured and cast in section before being delivered and installed at the bridge site. The reinforcing in the concrete deck
24 Apr 2017 concrete DECK SLAB. The most commonly constructed deck element is the concrete deck slab. This structural slab is designed to be between 7” and 9” thick and is reinforced with two layers of steel reinforcing bars.
This paper introduces a test program conducted for steel–concrete composite bridge decks with perfobond rib shear connectors. The composite deck consists of profiled steel sheeting, perfobond ribs, steel reinforcements, and concrete.
