Question

### Continuous One-Way Solid Slab Design

**Problem Statement:**

1. The cross section of a continuous one-way solid slab in a building is shown below. The slabs are supported by beams that span 12 ft between simple supports. The dead load on the slabs is that due to self-weight plus 77 psf of superimposed dead load; and the live load is 130 psf. Design the continuous slab and draw a detailed section. Given: \( f'_{c} = 3 \text{ ksi} \) and \( f_{y} = 40 \text{ ksi} \).

**Design Instructions:**

- Use a combination of #3, 4, 5 for main reinforcement.
- Use #3 for transverse reinforcement.
- You don’t need to consider the 2-way effect near girders.

**Diagram Explanation:**

The diagram illustrates a layout of a continuous one-way slab with dimensions marked as follows:

- Points A, B, C, D, and E indicate support and span locations.
- The slab spans are labeled as 1 ft at the beginning (A to B), 11 ft from B to C, C to D, and E to D.
- Each span between these points is supported by beams.
- The sections between D to E and beyond have identical 1 ft spans between support points D and E.

This layout assists in visualizing the span distribution and support points for the slab design.
