The coupler is installed by turning the the bar or sleeve with wrenches to the manufacturer’s specified torque. For splicing bent or curved bars, special position couplers with collars are used. Adaptations permit the use for end anchorages in concrete or connection to structural steel members. Bar ends may be shear-cut or saw-cut.

Thus, the GC used for TE 0 mode out-coupling also works for TE 1 mode, and the launched beam resembles LP 11 mode due to the field distribution of TE 1 waveguide mode.

When coupled shear wall (CSW) systems are built in a high seismic region, excessive shear forces are induced in the coupling beams. As a result of these shear forces, brittle failure of coupling beams and wall-coupling beam joints may occur or shear walls may yield first. The ductility demands on coupling beams can also be of critical concern.From the considerations outlined in Sect. 6.3, we adopt a co-axial laser beam configuration with the Rydberg laser counter-propagating with respect to the probe and coupling beams.

Recent studies developed new coupling beams by introducing mid-span dampers. The shear deformation is concentrated in the damper, thus protecting the primary concrete members. However, the concentrated shear deformation will result in slab damage.The rotation in the coupling beams was kept below the target of 0.05 Radians, the test-determined threshold at which the beams could accommodate rotation with minimal damage and loss of strength. Mean values of the seven ground motions were used to evaluate deformation-controlled actions. The tensile strains in the shear wallsA coupling beam in the RAM Concrete Wall module is a region within a Wall Panel that is bounded above and below by one or more wall openings or Wall Panel edges. Coupling Beams must be created by the user. At the user's direction, Coupling Beams may be reinforced like beams. That is, they may contain top and bottom bars, side bars, and stirrups.Often used for light duty encoder and stepper drive applications, they allow zero backlash (no play) and never need lubrication. They’re also known as helical beam couplings. Spiral couplings are less rigid than parallel couplings. Parallel couplings have short, intermittent slits in the body that create rigidity and high torque capabilities.
