10 performed tests on shear transfer mechanisms of a series of full-scale keyed joints, and concluded that the epoxied joints have consistently higher shear strength than dry joints.

9 concluded that the shear behavior of the dry keyed joints depends on the level of confining stress. Therefore, the shear performance of the joints has been attracting attention from researchers. But the reinforcement and concrete are discontinuous at the joint, which is the weak part of the structure 6, 7. Joints are the characteristics of the PCSB, which transmit the compressive and shear stress of joints 4, 5. Precast concrete segmental bridge (PCSB) has developed rapidly because of its advantages of economical and safe design, fast and versatile construction, no disruption at ground level, excellent serviceability, low life-cycle costs, and quality control readily achieved 1, 2, 3. Finally, the feasibility of steel shear keyed joints construction was verified via engineering tests. Based on traditional segmental bridges construction, construction methods involving steel shear keyed joints included short-line match, long-line match, and modular methods are introduced. However, different to the concrete epoxied joints which experienced brittle failure, steel key epoxied joints demonstrated a large residual capacity. Both the concrete key and steel key epoxied joints suffered direct shear failure. The results show that the stiffness and shear capacity of steel shear keyed joints were higher than concrete key joints, and the structural system was more stable than concrete keyed joints at the moment of cracking.

Various shear keys and joint types were taken as experimental parameters to study crack propagation, failure mode, shear slip, ultimate bearing capacity, and the residual bearing capacity of various joints under direct shear loading. In this study, a new steel shear key was designed, and 6 full-scale tests were conducted.

You can expect us to turn-key the entire process with the highest quality possible and provide you with a facility that can help give you a more competitive edge.The joints between segments represent weak points and introduce discontinuity into structures, therefore they are particularly significant in precast concrete segmental bridges. Regardless of your building requirements we can provide you with full-service capability. And within those facilities we have helped to design and construct several specialized areas including interior truck docks, bridge cranes, enclosed and elevated conveyor systems, areas requiring a special flooring material for optimum wear, and areas with special height requirements, just to name a few! Our industrial construction experience ranges from assembly plants to warehouse facilities, to light and heavy manufacturing - from 30,000 to 300,000 square feet. BEEM Construction has earned a reputation as Industrial Specialists throughout the Midwest (including Ohio & Michigan) because our clients get what they expect - projects completed within planned a time frames, within established budgets, and with a commitment from us of total satisfaction!
