Analysis of the structural behaviour of grouted pile/sleeve connections for offshore structures
… of the load-slip behaviour of individual shear keys of various shapes. The friction-gap element is adapted to give a representation of the shear keys using data derived from the detailed shear key analysis. A confinement factor is used to give higher ultimate shear key loads when the bond …

Effects of Delamination on Composite Sandwich Structures Under Static and Fatigue Loading
… and monotonic fracture. Fiberglass rods, called shear keys, added to the foam core to determine whether or not they increased the strength of the test specimens. Furthermore, shear key locations were also varied and their effects noted. The fixed rate static behavior for all of the above cases …

Development of Improved Connection Details for Voided Slab Bridges
… connection detail, a partial depth grouted shear key, has been known to fail in many of these bridges. The failure leads to reflective cracking in the wearing surface which allows chloride laden water to seep down through the joint, where it corrodes the reinforcement and prestressing …

VHPC Material Characterization and Recommendations for the Buffalo Branch Bridge Rehabilitation
… plants and are traditionally connected by a shear key filled with grout. This system is ideal for short spans with low clearance restrictions. However, due to the grout deteriorating and debonding from the precast concrete in the shear key, reflective cracking propogates through the deck …

Effects of Seawater on the Mechanical Behavior of Composite Sandwich Panels Under Monotonic Shear Loading
… the behavior of a composite boat hull under a shear loading, similar to the force water applies on the hull as the boat moves through the water; then attempt to strengthen the composite sandwich panel against the shear loading.</p> <p>A parametric study was conducted to investigate monotonic …

New Approach to Connections Between Members of Adjacent Box Beam Bridges
… system has long term durability issues caused by shear key failure and reflective cracking in the topping. The means and methods to alleviate the problems in connections between members of the ABBB were researched and the development of new connection details was pursued. Diagnostic tests to study …

Torsional Ground Motion Effects on the Seismic Response of Continuous Box-girder Highway Bridges
… of bent columns and abutment components such as shear keys, bearings, piles as well as the impact between deck and abutment, and abutment soil-structure interaction were explicitly included in OpenSees models. Furthermore, 3D FE models with a range of standard dimensions were altered to carry out …

In-Plane Shear Wall Performance As Affected by Compressed Earth Block Shape
<p>This thesis investigates the in-plane shear performance of full-scale walls made from compressed earth blocks. Compressed earth blocks are a type of masonry where the blocks are composed of compressed soil and typically dry-stacked without mortar. Prior research has demonstrated that the …

Experimental and Analytical Investigations of Piles and Abutments of Integral Bridges
… VDOT semi-integral abutment hinge experienced shear key failure as observed in two large-scale laboratory tests. The revised hinge detail did not exhibit any sign of damage. Both abutments tolerated 75-year worth of displacement cycles without any appreciable change in their behavior. …
