The back wall of the shed of Lab. 12a is to be supported by a reinforced concrete spread foundation. The distributed load on the wall is 316 lb/ft and a 10% self-weight allowance should be made for the wall. The studs inside the wall are spaced at 24” and the top of the footing is 12” below ground level. The concrete is to be made from 3 ksi concrete grade and reinforced with steel bar of 36ksi yield strength. Design the foundation for the wall. Take the soil bearing pressure capability as 2 ksf and the weight density of steel concrete as 150 lb/ft³ and that of the soil as 100 lb/ft³. The weight of steel reinforcement is considered negligible.

Polyester resins reinforced with fiberglass are used to fabricate wall panels of restaurants. It is theorized that adding cement kiln dust (CKD) to the polyester composite will increase wall panel hardness. In a study, hardness (joules [J] per squared centimeters) was determined for three polyester composite mixtures that used a 40% CKD weight ratio. The hardness values were reported as 83, 82, and 77 J/cm2. Research has shown that the mean hardness value of polyester composite mixtures that use a...
