Webanchor bolt equals 36 ksi and 58 ksi, respectively. It should be noted that the governing failure mode, including a ductile versus brittle failure m ode, may change as specified values are changed. e) Anchor bolts are hex headed The bolt type and head affect assumed properties . used in design such as bearing area. Web$\begingroup$ Failure for shear in the plastic would occur at the perimeter of the washer, so if it's 2" square, your area resisting shear would be the perimeter times the thickness (8" * 1/8" = 1 Square Inch.) If the nut if more than snug tight, the preload will add some shear stress before there is any uplift on the plastic sheet.I'm sure someone who knows about …
