A steel plate 5/16" thick is embedded in a horizontal concrete slab and is used to anchor a high-strength cable as shown. The diameter of the hole in the plate is 3/4", the ultimate strength of the steel used is 36 ksi, and the ultimate bonding stress between plate and concrete is 300 psi. Knowing that a factor of safety of 3.6 is desired when P = 2.5 kips, determine; The required width a of the plate (assume an average stress distribution across the reduced cross-section through the 3/4" hole), the minimum depth b to which a plate of that width should be embedded in the concrete slab. (Neglect the normal stresses between the concrete and the bottom edge of the plate.)
Design a series of closely spaced parallel box beams that will support an asphalt road surface over a 10 foot wide, 40 foot long span. The hollow box beams are made of concurred and imbedded No. 8 steel rods (1 inch dia.).
The city has a stable population of 235,000 residents and the design criteria for the new landfill are as follows: MSW generation rate = 4.0 lb/(person-day); density of the compacted MSW in the landfill is 775 lb/yd3
Compute the maximum acceptable service load on an A36 steel plate tension member 1/4in.x12in. having a single line of holes parallel to the direction of loading. The load is 25% dead load and 75% live load, and 7/8in. diameter bolts are used.
