Question

Muller-Breslau principle is used in analysis of structures for \underline{\hspace{2cm}.}

• A. drawing an influence line diagram for any force response in the structure
• B. writing the virtual work expression to get the equilibrium equation
• C. superposing the load effects to get the total force response in the structure
• D. relating the deflection between two points in a member with the curvature diagram in-between

Hint:

When analyzing structures, the Muller-Breslau principle can simplify complex load effects by helping to create influence lines for different types of responses, aiding in more efficient calculations.

Answer 1

The Correct Option is A

The Muller-Breslau principle is used for the analysis of structures to help with determining influence lines for various force responses. It allows for the visualization and calculation of the effect of loads on different points within the structure. The principle is fundamental in structural analysis when we need to understand how different forces are distributed and the corresponding responses.
In this context, the principle is specifically used for drawing an influence line diagram for any force response in the structure, which makes option (A) the correct answer.
