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.

Question

The diagram displays a structural framework with labeled points and forces applied. It comprises two levels, each with rectangular sections, and horizontal and vertical dimensions provided.

**Dimensions and Layout:**

- **Height:** The total height is divided into two sections, each measuring 15 feet.
- **Width:** The lower level has two sections, measuring 18 feet and 20 feet respectively.

**Points and Force Directions:**

- The structure consists of intersecting points labeled A, B, C, D, E, F, G, H, and I.
- A horizontal force of 3 kips (k) is applied leftward at point I.
- A horizontal force of 4 kips (k) is applied leftward at point D.

Each section formed by intersecting lines represents segment divisions of the structure, which could signify beams or load-bearing components in an engineering context.

Draw the (a) axial (b) shear and (c) bending moment diagram of the girders. Use portal method for structure (1), cantilever method for structure (2) and Factor Method for structure (3). All columns have the same area. The beams and columns have the same modulus of elasticity. Assume moment inertia of beams is twice the moment of inertia of columns.
