Key Concepts

Internal Forces in Structural Members

Internal forces, including axial forces, shear forces, and bending moments, develop within a structural member as a response to externally applied loads or external pretensioning. The correct determination of these forces is crucial for assessing the member’s capacity to carry loads and ensuring its structural safety.

Free-Body Diagram and Cut Section Analysis

Free-body diagrams and section cuts are fundamental tools in mechanics used to isolate a part of a structure in order to analyze its internal loadings. By cutting through a member and considering all external and reactive forces acting on the isolated segment, one can establish equilibrium equations that lead to the determination of the internal force distributions.

Equilibrium Analysis

This concept involves applying the static equilibrium equations to a structure or a segment of a structure. It requires that the sum of forces and moments about any section is zero. Using equilibrium analysis allows one to solve for unknown internal forces—such as axial forces, shear forces, and bending moments—that develop in a member when external loads or prestresses are applied.

Pretension in Structures

Pretension refers to the intentional application of a force to a structural member before it is subjected to its service loads. This initial force affects the way the structure responds to additional loads, altering internal force distributions and possibly improving performance or stability under operating conditions.
