Question

A girder supports concentrated dead and live loads. Determine the following required

strengths for the girder based on the controlling load combinations.
Use statics or Table 3-22a from the Steel Manual.
- The maximum bending moment, MD (kip-ft), due to dead load.
- The maximum bending moment, ML (kip-ft), due to live load.
- ASD required flexural strength, Ma (kip-ft)
- LRFD required flexural strength, Mu (kip-ft)

**Diagram Explanation: Simply Supported Beam with Uniform Point Loads**

**Description:**

The diagram illustrates a simply supported beam subjected to multiple point loads. The beam rests on two supports, positioned at each end, depicted as triangular shapes.

**Loads:**

- The beam is loaded with three sets of point loads, denoted as \( P_D \) and \( P_L \).
- Each point load is applied vertically downwards along the beam.

**Load Values:**

- \( P_D = 20 \) kip
- \( P_L = 30 \) kip

**Spacing and Dimensions:**

- The total span of the beam consists of four sections.
- Each section spans 7.0 feet, resulting in an overall length of \( 4 \times 7.0 \text{ ft} = 28 \text{ ft} \).

This type of configuration is typical in structural analysis to determine reactions, shear forces, and bending moments in beams.
