Steel Design

Use this for “A member yields at a nominal strength of 100 kips. Find its LRFD design strength (φ = 0.9) and ASD allowable strength (Ω = 1.67).”

Use this for “Is the weight of movable furniture a dead load or a live load in the LRFD combinations?”

Use this for “An 8 in × ¾ in plate with Fᵧ = 50 ksi and Fᵤ = 65 ksi has two 1 in holes across it. Find φPₙ.”

Use this for “A floor beam spans 20 ft with Iₓ = 518 in⁴ and carries a service live load of 1.2 kip/ft. Is its sag within L ÷ 360?”

Use this for “A W18×50 of 50 ksi steel has d = 18 in and tw = 0.355 in. What factored shear can it carry?”

Use this for “A plate is welded to a gusset by two ⅜ in E70 fillet welds, each 8 in long. Find the strength per inch and φRₙ.”

Use this for “A bolted end has Agv = 4.5 in², Aₙᵥ = 3.2 in² and Aₙₜ = 1.1 in², with Fᵧ = 50 ksi and Fᵤ = 65 ksi. Find its block shear strength.”
