Topic 1: Types of Structures, Internal Forces, Forms of Structures, and Types of Joints in Framed Structures

In structural engineering, it is essential to understand the different types of structures and the forces they experience. Structures can be classified as framed, truss, shell, or solid structures, each serving specific purposes in construction. These structures are designed to withstand various internal forces such as tension, compression, shear, bending moment, and torsion. The form or shape of a structure—such as rectangular frames, trusses, or arches—affects its strength and stability. Lastly, the connections or joints between structural members, including pinned, fixed, and roller joints, play a crucial role in how forces are distributed and how the structure responds to loads. Mastering these fundamentals forms the foundation for analyzing and designing safe and efficient structures.
