Abstract:

Two novel demountable shear connectors for precast steel-concrete composite bridges are presented. The connectors use high-strength steel bolts, which are fastened to the steel beam with the aid of a special locking configuration that prevents slip of bolts within their holes. Moreover, the connectors promote accelerated construction and overcome typical construction tolerances issues of precast structures. Most importantly, the connectors allow bridge disassembly, and therefore, can address different bridge deterioration scenarios with minimum disturbance to traffic flow, i.e. (1) precast dec

The objective of the research presented in this thesis was to develop a concrete bridge deck topping mixture that resists the effects of differential shrinkage by decreasing shrinkage and increasing creep. . In addition, the amount of tensile creep that concrete experiences under long-term tensile stresses were quantified and compared to compressive creep values in order to gain a better understanding of how concrete behaves under tension. Test results show that the amount of tensile creep exceeded compressive creep by a factor of 2-5. Various shrinkage and creep models were compared against

Abstract:

The continuous permanent metal deck form system provides a quick and efficient method of constructing short-span, simply supported composite steel girder bridges. However, because shear studs can only be welded to the girder through the steel deck at rib locations, the number of shear stud locations is limited to the number of ribs in the shear span while the spacing of the shear studs is restricted to the rib spacing of the steel deck. This results in a condition where various provisions of the AASHTO LRFD Bridge Design Specifications (2007) cannot be satisfied, including shear stud fatigue s

The inverted T-beam bridge system provides an accelerated bridge construction alternative for short-to-medium-span bridges. The system consists of adjacent precast inverted T-beams finished with a cast-in-place concrete topping. The system offers enhanced performance against reflective cracking, and reduces the likelihood of cracking due to time dependent effects. The effects of transverse bending due to concentrated wheel loads are investigated with respect to reflective cracking. Transverse bending moment are quantified and compared to transverse moment capacities provided by a combination

Each bridge section consisted of two built-up steel plate girders intact with the precast concrete deck panels.

Abstract:

Under-deck cable-stayed bridges (UDCSBs) are an innovative typology of cable-stayed bridges, in which the stay cables are located underneath the deck. UDCSBs with prestressed concrete decks present an efficient structural behaviour due to the enhanced axial response. Hence, UDCSBs lead to a more sustainable construction compared to bridges without cable-staying systems. However, UDCSBs with steel-concrete decks, which seem prima facie to be an appropriate solution, have not been investigated hitherto in depth. Thus, the behaviour of UDCSBs with steel-concrete decks when used for road construct

Abstract:

The use of high strength steel has the potential to reduce the amount of steel used in bridge structures and thereby facilitate a more sustainable construction. The amount of steel and what steel grade that can be used in bridge structures and other cyclic loaded structures are often limited by a material degradation process called fatigue. The fatigue resistance of steel bridges are to a large extent depending on the design of structural details and connections. The design engineer is limited by a few pre-existing structural details and connections – with rather poor fatigue resistance – to c

The Ångermanälven Bridge (railway bridge part of the Bothnia line project) was designed with big edge beams of width 1.2 m, 40 % of the total area of the concrete deck cross-section.

Historically, they have been limited to spans of less than 10 m. Renewed research interest over the past two decades has shown great potential for longer span capabilities. Through composite action and suitable detailing, improvements in strength, stiffness, and durability can be achieved versus conventional wood bridges.

The traffic network may accordingly be hurt or even ruptured and gives trouble to people live in the area isolated by broken bridges. In order to provide the effective emergence rescue, a kind of easy-erection temporary bridge for traffic is required to shorten time of social restoring after disaster. The fiber reinforcing plastic (FRP) has advantages of high strength, lightweight and good durability for reuse, etc., a

Abstract:

Tese de Doutoramento em Engenharia Civil - Ramo do Conhecimento Estruturas<br>The behaviour of composite structures accounts for the contribution of concrete and steel sections, provided that a composite action exists between these two materials. Composite action can be obtained by reducing or preventing the relative displacement of concrete and steel elements at their interface. Shear connectors are used to provide this composite action. The behaviour of the steel to concrete connection will have major importance on the global behaviour of the structural element. Lightweight concrete is now
