Key Concepts

Equilibrium Analysis

Equilibrium analysis is based on the principle that a structure or a segment of a structure in a static condition must satisfy the conditions of equilibrium. This involves ensuring that the sum of forces in all directions and the sum of moments about any point are zero. It is a critical procedure for deriving the internal forces and moments acting on any cross section of a structure.

Resultant Internal Loadings

This concept involves the net forces and moments that develop within a structure when an external load is applied. In structural analysis, determining these resultant effects on a cross section is essential for understanding how internal forces such as shear, axial loads, and bending moments are distributed within a member. It helps in assessing the structural capacity and ensuring safety and stability under applied loads.

Free?Body Diagrams

A free?body diagram (FBD) is a simplified representation of a structural element or a segment of a structure isolated from its surroundings. It shows all external loads, reactions, and internal force effects that act on the chosen section. FBDs are a fundamental tool in mechanics used to apply equilibrium equations and solve for internal loading components.

Internal Force Components

Structures under load typically experience various internal forces which include axial forces, shear forces, and bending moments. Understanding each of these components is key to assessing how a structure carries and transfers loads. Axial forces relate to tension or compression, shear forces indicate a tendency for two adjacent parts to slide relative to one another, and bending moments relate to the tendency of a section to rotate, each contributing to the overall stress distribution in the structure.
