Behaviour of continuously supported self-compacting concrete deep beams
… were the shear span-to-depth ratio, the amount and configuration of web reinforcement and the main longitudinal reinforcement ratio. All beams failed due to a major diagonal crack formed between the applied mid-span load and the intermediate support separating the beam into two blocks: the first …

Automatic design of concrete structures using a strut & tie approach
… in this thesis is an investigation of the strut and tie method for designing 2-D in-plane, reinforced concrete structures. Two important issues relating to this method are addressed. Firstly, the issue of visualising an appropriate strut and tie model is dealt with. In many situations it …

The Development of a Steel Embedded Connection for Double-Tee Beams
… as a shooter. The shooter is provided in capacities, a 40 kip capacity shooter and a 50 kip capacity shooter. This steel connection is embedded near the end of a double-tee prestressed girder. Double-tee prestressed girders are a primary component used in the construction of parking garages. …

Linear and Nonlinear Finite Element Analyses of Anchorage Zones in Post-Tensioned Concrete Structures
Linear and nonlinear finite element analyses are used for the investigation of rectangular anchorage zones with the presence of a support reaction. The investigation is conducted based on four load configurations consisting of concentric, inclined concentric, eccentric, and inclined eccentric …

Seismic Performance of Column-to-Drilled-Shaft Connections in Reinforced Concrete Bridges
… to allow tolerance in the column placement and to facilitate plastic hinge formation in the column rather than in the shaft. The column-shaft connection, which involves a noncontact splice between the column and shaft bars, is a key component in this structural system. However, there is …

Behavior of Deep Reinforced Concrete Beams under Monotonic and Reversed Cyclic Load
… non-slender beams under monotonic and reversed cyclic loads, as particular consideration is given to the load-bearing mechanisms which occur in moderately-deep beams. The choice of this topic was motivated in part by verification studies which show that the current code procedures …

Rehabilitation of concrete girders with distressed end regions using innovative materials
… severe damage to the structural integrity and durability of the bridges. Among all types of damage, the distressing of end regions in bridge girders is very commonly observed. This damage could be in the form of cracking and spalling of concrete and steel corrosion. This research focuses on …

Anchorage Zone Design for Pretensioned Bulb-Tee Bridge Girders in Virginia
… in the United States. The application and diffusion of the prestress force in a pretensioned girder causes a vertical tension force to develop near the end of the beam. Field surveys of the beam ends of pretensioned bridge girders indicate that many of the PCBT beams used in the …

Inelastic web crushing performance limits of high-strength-concrete structural walls
… piers with highly-reinforced boundary elements and the connecting walls. However, current conservative design approaches result in massive cross sections that can lead to increased construction cost. This study investigates the feasibility of defining new limits for a seldomly considered failure …

Kinematics-Based Modelling of Deep Transfer Girders in Reinforced Concrete Frame Structures
… of the shear mechanisms of deep beams, and a number of formulations and models have been proposed attempting to explain their behaviour. However, up to the present, the accurate prediction of the shear response of deep beams remains a challenge. Considering the importance of such kind of …

Behaviour of continuous concrete deep beams reinforced with GFRP bars
… For this purpose, experimental, analytical and numerical studies were conducted. Nine continuous concrete deep beams reinforced with GFRP bars and one specimen reinforced with steel bars were experimentally tested to failure. The investigated parameters included shear span-to-overall depth …
