Force Method of Analysis: General Procedure
Understand the Problem
This is a textbook excerpt about the force method of analysis, specifically regarding general procedures. It explains how to calculate displacement and reactions in structures using concepts such as linear flexibility coefficient and compatibility equations. The excerpt provides equations and refers to figures and chapters within the textbook for further information on applying the force method.
Answer
The force method involves selecting redundants, creating a primary structure, and using compatibility equations to solve for unknowns.
The force method of analysis involves selecting unknown redundants, removing redundant reactions to obtain a primary structure, formulating compatibility equations, and solving for the redundants using equilibrium equations.
Answer for screen readers
The force method of analysis involves selecting unknown redundants, removing redundant reactions to obtain a primary structure, formulating compatibility equations, and solving for the redundants using equilibrium equations.
More Information
The force method is also known as the flexibility or compatibility method and is used to analyze indeterminate structures by treating redundant forces as unknowns.
Tips
A common mistake is incorrectly identifying the redundant forces. It is important to carefully consider the structure and its supports to choose the most suitable redundants.
