Design a bearing plate for a W30x108 to support a reaction of 78 composed of equal live live and dead load. Use ASD. Concrete bearing surface will be 1 inches wider than the bearing plate on all sides, F? = 3 ksi.
To design a bearing plate for a W30x108 steel beam supporting a reaction of 78 kips (composed of equal live and dead loads) using Allowable Stress Design (ASD) method, we need to follow these steps:
Determine the required bearing area:
First, we need to determine the required bearing area by dividing the total reaction by the allowable bearing stress on the concrete surface.Given:
Total reaction (R) = 78 kips
Concrete compressive strength (f'c) = 3 ksiThe allowable bearing stress for concrete (?c) is given as: Required bearing area in^2
