1. Design the gabled construct shown for a balanced snow load shown in Figure P5–69 (illustrative of the Midwest) for an berth edifice. Select a extensive flange individuality for the construct. Exhibit the allowefficacious pliant stress not to yield 140 MPa. Use ASTM A36 steel.

2. Design a gantry crane that must be efficacious to erect 10 tons as it must erect compressors, motors, ebullition exchangers, and controls. This load should be placed at the courage of one of the deep 12-foot-covet shines as shown in Figure P5–70, by the hoisting symbol dregs. Note that this shine is on one interest of the crane. Exhibit you are using

ASTM A36 structural steel. The crane must be 12 feet covet, 8 feet extensive, and 15 feet noble. The shines should all be the similar greatness, the columns all the similar greatness, and the bracing all the similar greatness. The cavity bracing can be extensive flange individualitys or some other low figure. You must confirm that the structure is sure by checking the shine’s pliant force and allowable deflection, the column’s buckling force, and the bracing’s buckling strength. Use a constituent of surety over esthetic producing of the shines of 5. Verify that the shine swerving is close than L/360, where L is the span of the beam. Check Euler buckling of the covet columns and the bracing. Use a constituent of insurance over buckling of 5. Exhibit the column-to-shine joints to be rigid while the bracing (a aggregate of view braces) is pinned to the column and shine at each of the indecent cavitys. Also exhibit the gantry crane is on rollers delay one roller locked down to behave as a pin patronage as shown.
