The fundamental requirement of structural design is that the available strength exceed or equal the required strength.

The client is taking an opioid pain medication at home after surgery.  What instruction does the nurse give this client?

The allowable strength is the _______ strength divided by the _______ factor.

A column is loaded in compression as follows. Using ASD, determine the required nominal strength for a safety factor Ω = 1.60.Dead load: 17 kipsFloor live load: 5 kipsRoof rain load: 3 kipsRoof live load: 7 kips

To prevent _______, the stress on the net section must be less than the tensile strength, Fu.

A 3/4 in. x 3 in. plate must resist a service dead load of 32 kips and a service live load of 40 kips in tension. The plate is connected to a gusset with three 1 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. Using LRFD, does the plate have enough strength?

The _______ factors account for uncertainties in material properties, design theory, and fabrication and construction practices.

Is structural steel considered a ductile or brittle material?

A 0.93 in. x 4.6 in. plate is connected to a gusset with three 7/8 in. bolts. Standard sizing is used for the bolt holes. What is the gross area of the plate?

A tensile test was performed on a specimen with a circular cross section. The diameter was measured to be 0.880 inch. Two marks were made along the length of the specimen and were measured to be 2.500 inches apart. This distance is defined as the gage length, and all length measurements were made between the two marks. The specimen was loaded to failure. Fracture occurred at a load of 17,500 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.406 inch and 2.684 inches. Determine the ultimate tensile stress.
