Types and properties of steel

Steel is an alloy of iron. It is formed by heating iron and combining carbon (0.1-1.7%) with it and minor amounts of other elements such sulfur, chromium, manganese, nickel, etc. Thousands of steel grades have been published, registered, or regulated around the world, each with its chemical composition, and special numbering systems have been devised in various countries to classify the vast number of alloys.

### Structural Engineering Example: Floor System Load Calculation

**Problem Statement:**

The steelwork framing plan for a floor system shows decks as D1-D12, beams and girders as M1-M20, and columns as C1-C9. The unit load on the system is 75-psf dead and 45-psf live.

**Question:** What is the total load going into column C2?

**Diagrams Explanation:**

The diagram provided is a plan view of a steel framing system. Here's a detailed description:

1. **Columns (C1-C9):** These are the vertical bearings marked as C1 to C9.
2. **Beams and Girders (M1-M20):** Horizontal supports marked as M1 to M20.
3. **Decks (D1-D12):** Decking material indicated by D1 to D12.
4. **Dimensions:**
- The vertical height is labeled as 40 feet.
- The horizontal lengths are divided into sections of 16 feet and 24 feet, totaling 40 feet horizontally as well.

**Calculation Process:**

To calculate the load going into column C2, follow these steps:

1. **Identify Tributary Area for Column C2:**
- The tributary area is the area of the floor system that contributes to the load on C2.
- The tributary area is determined by the midpoint spacing between adjacent columns and beams.

2. **Determine Dimensions:**
- When considering tributation, let's assume C2's tributary area extends halfway to adjacent columns and beams.
- The tributary area for column C2 will span half the distance to adjacent columns and beams, covering an area defined by:
- Horizontally: 16 feet + 16 feet / 2 = 24 feet.
- Vertically: 36 feet / 2.

3. **Convert the loading units to total area:**
- Dead load: 75 psf (pounds per square foot).
- Live load: 45 psf.

4. **Calculate the Total Load:**
- Total area contributing to load on C2 = 24 feet x 20 feet.
- Dead Load Contribution = Total Area x Dead Load.
- Live Load Contribution = Total Area x Live Load.
- Total Load = Dead Load Contribution + Live Load Contribution.

An office decided to centralize its paper files. All the file cabinets in one department will sit in a row. The file cabinets sit over a floor joist. The cabinets are positioned perpendicular to the joist with the centers based on depth directly over the joist. Each file cabinet is 18 in. wide by 30 in. deep and weighs 300lb. Determine: (a) the total load on the one joist (neglect the weight of the floor itself) (b) the load transferred to the beam located at each end of the joist (assume the cabinets are centered on the joist length) (c) the maximum bending moment in the joist (d) the maximum flexural stress in the joist
