Final answer:
To design an A36 steel beam with a 30' span and a 1k/foot load, follow these steps: calculate the total load, determine the maximum allowable deflection, and select an appropriate beam.
Explanation:
To design an A36 steel beam, we need to consider the span and the load it will carry. Given a 30' span and a uniformly distributed load of 1k/foot, we need to determine the appropriate wide flange steel beam and limit the deflection to 1/360 of the span.
- First, we calculate the total load on the beam by multiplying the load per foot (1k/foot) by the span (30'). This gives us a total load of 30k.
- Next, we need to determine the maximum allowable deflection. Since the deflection limit is 1/360 of the span, we divide the span (30') by 360 to get the maximum deflection of approximately 0.083 feet.
- Using the maximum allowable deflection and the total load, we can select a wide flange steel beam that meets these criteria. The selection process involves checking various beam tables and cross-referencing the load and deflection requirements with available beam options.
