Block Shear Strength. Block shear is a combination of tensile rupture, and either shear yielding or shear rupture. The program checks both types of block shear per the AISC 360-10 specification, section J4.3. Note: When multiple rows of bolts are present for a block shear calculation, a U bs value of 0.5 is used.

14/1/2013 · Block shear is, in some ways, similar to tensile rupture in that the main part of the member tears away from the connection. The provisions for block shear are found in SCM J4.3 (SCM page 16.1-129). The difference is that there is now a combination of tension and shear on the failure path.

Block shear is the tearing out of a block of material at a connection as shown in Figure 2. Numerically, it is the sum of shear yield or shear rupture on a failure path parallel to the load and tension rupture perpendicular to the load. It most often applies on coped beam sections, gusset plates, and angle legs.
