Punch shear
WebGenerally I've seen strap or grade beams used for beam behavior and preventing differential movement. If punching shear was controlling in the footing, the strap beam might need to be much thicker than the footing to not also have shear issues, i.e., the punching perimeter for the footing in the sketch seems stronger in 2way than the sketched beam in 1way. WebIn shear punch testing (93,94), the disk is clamped, the punch is a flat cylindrical penetrator, and the die is a close fit to the punch diameter. The contact angle between the punch and the specimen remains constant with applied force as the punch travels through the specimen, and shear properties (rather than tensile properties) are directly measured.
