 (11) Check resistance in shear.
Interior support (combined shear and bending).
Determine dynamic shear capacity of a 1-ft width of panel.
h = (1.500 - 2t) where t = 0.043 in
= 1.500 - 0.086
= 1.414 in
h/t = 1.414/0.043 = 33 > 30
Fdv = 10.80 ksi
Total web area for 1-ft width of panel:
(8 x h x t)/2 = 4 x 1.414 x 0.043 = 0.243 in2/ft
Vp = 0.243 x 10.84 = 2.63 kips/ft
Determine maximum dynamic shear force:
The maximum shear at an interior support of a continuous
panel is:
V = 0.625ruL
= 0.625(1,111.8 x 4.5)/1000
= 3.127 k/ft.
V > Vp
or 3.127 > 2.630
No Good.
