S Section FIGURE P323 APLx6tension member is steel is A36 As

S- Section FIGURE P3.2-3 APLx6tension member is steel is A36. Assume that A, A, and compute the following. a. The design strength for LRFD. b. The allowable strength for ASD. 32-4 APLx6 tension member is welded to a gusset plate as shown in Figure P3.2-4. The :and compute 3.2-4 ameter bolts, as shown A,A, and compute the FIGURE P3.2-4 ion member shown in Figure P3.2.5 is a PL tax 8 of A36 steel. The mem- ted to a gusset plate with-1% inch-diameter bolts. It is subjected to the dead and live loads shown. Does this member have enough strength? Assume that a. Use LRFD b. Use ASD FIGURE P3.2-5

Solution

GIVEN plate sige PL 3/8X6

A_g= A_c = 3/8*6=2.25 in²

ultimate strength= 58ksi

Pn= 58*2.25=130.5 kips

For LFRD

= 0.75

Pn= 0.75*130.5 =97.875 kips

for ASD

=2

Pn/ = 130.5/2=65.25 kips
