A shear plate shear connection, also known as a shear tab or shear plate connection, is a type of connection used to transfer shear forces between a steel beam and a column or other structural member. It consists of a plate that is welded or bolted to the beam flange and connected to the column or member through bolts or welds. The shear plate connection provides an efficient means of transferring shear loads while allowing for rotational movement between the connected members.

Here are some key considerations and steps involved in the design of a shear plate shear connection:

Determine the design requirements: The design requirements for the shear plate connection are typically specified in the project specifications or design codes. This includes the required shear capacity, the material properties, and any specific connection details.

Calculate the required shear capacity: The required shear capacity of the shear plate connection is determined based on the applied loads and the design criteria. This involves considering factors such as the magnitude of the shear force, the strength of the connected members, and any applicable safety factors.

Select the shear plate dimensions: The dimensions of the shear plate, including its thickness and width, are selected based on the calculated shear capacity and the available space for the connection. The shear plate should be designed to adequately transfer the shear forces without excessive deformation or failure.

Design the connection details: The connection details include the configuration and arrangement of the bolts or welds that connect the shear plate to the beam and column. The design should ensure that the connection can effectively transfer the shear forces and accommodate any necessary rotational movement between the members.

Check the adequacy of the welds or bolts: The welds or bolts used in the shear plate connection should be designed and checked for their capacity to resist the applied shear forces. This involves considering factors such as the strength of the weld or bolt material, the size and spacing of the welds or bolts, and any applicable design criteria or standards.

Consider construction and installation requirements: The design of the shear plate connection should consider the practicality of fabrication and installation, including access limitations, welding or bolting procedures, and any required tolerances or clearances.
