Shear design

Off-Gas Treatment. Before the advent of the shear, the gases released from the spent fuel were mixed with the entire dissolver off-gas flow. Newer shear designs contain the fission gases and provide the opportunity for more efficient treatment. The gaseous fission products krypton and xenon are chemically inert and are released into the off-gas system as soon as the fuel cladding is breached. Efficient recovery of these isotopes requires capture at the point of release, before dilution with large quantities of air. Two processes have been developed, a cryogenic distillation and a Freon absorption. 

Compression shear tests are also commonly used. ASTM D 2182 describes a simple compression specimen geometry and the compression shear test apparatus. The compression shear design also reduces bending and, therefore, peeling at the edges of the laps. Higher and more realistic strength values are obtained with the compression shear specimen over the standard lap shear specimen. 

Lodige horizontal plough shear design where tools push material into relatively large chopper zones (Iveson et al., loc. cit., 2000), or in Gral top-driven designs, which possess much larger choppers. 

Usually, for shear design the well-known classical truss model is used. The shear strengthening design also requires knowledge and understanding of the cmcial failure modes of the externally bonded shear reinforcement (EBSR). 

Similar to the design of flexural strengthening, the following states for the shear design of reinforced concrete (RC) members can be distinguished as the stmctural loads increase ... 

A disadvantage of the gap shear design is that the cutout in the side housings requires that the structural members must be reinforced. Without the added reinforcement, when the machine is under load, the housings deflect, or open up, causing shearing inaccuracy. To overcome deflection, gap shears require rein-...

Although both hydraulic and mechanical shear designs have their merits, you should evaluate your present and future shearing application needs before making your final choice. The three general factors that should be considered as follows ...

The minimum of the following strengths should be taken as the shear design strength, V of the anchorage. 

As a result, beam-column joints are susceptible to shear failure which generally involves a brittle process. Such brittle shear failure must be avoided through appropriate design to ensure ductile response of the frame. Despite the importance of shear design of RC beam-column joints, the research community has not yet developed a commonly accepted approach for the determination of the shear strength of RC beam-column joints, probably due to the complexity of joint behavior.
