Abstract:
Jointless bridges are advantageous in removing mechanical joints which are a known cause of bridge deterioration. Elimination of joints provides a smoother riding surface and removes the possibility of de-icing salts penetrating the deck and corroding the deck reinforcing and underlying bridge superstructure. Jointless bridges are traditionally constructed by monolithically casting the entire bridge deck on beams after they have been erected. However, this process requires extensive in-field formwork and lengthy traffic closures. The Texas Department of Transportation proposes a new method of

An elastic analysis of restrained slab strips shows that membrane action enhances serviceability behaviour. However, the enhancement is not as great as for strength and serviceability is critical when membrane action is considered in design. A relatively simple form of non-linear finite element analysis is developed which is able to model bridge deck behaviour allowing for membrane action. This reduces some of the disadvantages of non-linear analysis which have prevented its use in practice. It uses line elements but, because of novel features of the elements and because it considers all six d

Circular voids are often incorporated into concrete bridge decks to reduce their self-weight without greatly reducing the flexural stiffness. Incorporating voids within a slab offers many advantages over a conventional solid concrete slab, for example a lower total cost of construction, reduced material use, and enhanced structural efficiency. The advantages of this topology are obvious, however the voids within the slab complicate the analysis of the structure.

Since concrete bridge deck slabs are much longer in the traffic direction, they experience transverse early-age cracks due to volumetric instability and restraint. In the last decade, the lower cost of the non-corrodible Glass Fiber Reinforced Polymer (GFRP) bars, as alternative to steel reinforcement, has made them attractive to the bridge construction industry. However, low modulus of GFRP bars may lead to wider cracks in GFRP-RC structures. This serviceability issue can be aggravated by harsh environmental conditions.

Abstract:
This thesis summarizes the results of an experimental investigation of the behaviour of headed stud connectors in push-out specimens with headed studs embedded in solid slabs and in slabs with wide ribbed metal deck oriented parallel to the beam. The experimental investigation involved the testing of 104 push-out specimens and was conducted in three phases. The first phase involved a study of the effects of transverse stud spacing on the shear strength of headed studs in push-out specimens with solid slabs and those with wide ribbed metal decks. The objectives of the second phase were to condu

Abstract:
A composite steel-concrete slab consists of a concrete topping cast on the top of a profiled steel deck. Normally, the concrete is reinforced with an anti-crack mesh positioned on the upper part and individual reinforcing bars placed within the ribs. The steel deck acts as a permanent formwork and the composite action between the steel and concrete is generally achieved by indentations or embossments in this component. Composite slabs play an important role in the overall stability of buildings during fire exposure, and should be designed in accordance with regulations and standards. The fire
