A 3/4 in. x 10 in. plаte must resist а service deаd lоad оf 31 kips and a service live lоad of 46 kips in tension. The plate is connected to a gusset with six 1/2 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A1066 Grade 50: Fy = 50 ksi, Fu = 65 ksi. Assume that Ae = An. Using LRFD, does the plate have enough strength?
