The fundamental requirement of structural design is that required strength is _______ available strength.

For LRFD, the resistance factor for yielding is larger than the resistance factor for fracture.

Working loads are also known as _______.

To prevent excessive deformation, the load on the gross section must be small enough that the stress on the gross section is less than the yield strength.

A 0.80 in. x 3.2 in. plate is connected to a gusset with three 1-1/4 in. bolts. Standard sizing is used for the bolt holes. What is the net area of the plate?

All building codes in the United States are the same and come from a national standard created by Congress.

For LRFD, the resistance factor for fracture is ____.

A tensile test was performed on a specimen having a circular cross section with a diameter of 0.500 inch. The gage length (the length over which the elongation is measured) is 1.5 inches. For a load of 15.0 kips, the elongation was 0.00805 inches. If the load is assumed to be within the linear elastic range of the material, determine the modulus of elasticity.

A 1/2 in. x 5.0 in. plate is connected to a gusset with four 7/8 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A572 Grade 60: Fy = 60 ksi, Fu = 75 ksi. Assume that Ae = An. Compute the design strength for LRFD.

A 3/4 in. x 8 in. plate must resist a service dead load of 32 kips and a service live load of 52 kips in tension. The plate is connected to a gusset with six 1-1/8 in. bolts. Standard sizing is used for the bolt holes. The steel is ASTM A572 Grade 42: Fy = 42 ksi, Fu = 60 ksi. Assume that Ae = An. Using ASD, does the plate have enough strength?
