Question
The beam shown below is a W16 x 31 of A992 steel. It supports a reinforce concrete floor
slab that provides continuous lateral support of the compression flange. The service dead
load is 450 lb/ft. this load is superimposed on the beam; it does not include the weight of
the beam itself. The service live load is 550 lb/ft.
- Is the section compact? Show.
- Does this beam have adequate moment strength and shear strength?
Is the beam satisfactory for deflection, if the maximum permissible live load deflection is L/360
Transcribed Image Text:The image depicts a beam under a uniform load. The beam is supported at two points: a pinned support on the left and a roller support on the right. The uniform load is represented by downward arrows distributed evenly along the length of the beam, indicating that the load is spread consistently across it.
Key features of the diagram:
- **Beam Length**: The beam is 30 feet long, as indicated by a horizontal double-headed arrow underneath the beam, marked "30'."
- **Supports**:
- The left side of the beam shows a triangular symbol, indicating a pinned support. This type of support allows rotation but prevents translation in any direction.
- The right side has a circular symbol over a horizontal line, signifying a roller support. This allows horizontal movement but prevents vertical translation.
- **Uniform Load**: The downward arrows across the beam represent a uniform load applied to it.
This type of diagram is commonly used in structural engineering to analyze forces and reactions in beams.
