3 cards from this section. Quick, good the night before a test.
What is the purpose of idealization in structural analysis?
Think about what steps we take to reduce complexity.
Define a stiffness matrix.
Focus on the relationship between forces and displacements.
What does idealization in structural analysis involve?
Think about whether models simplify or complicate the analysis.
True or False: The stiffness matrix only relates to axial deformation.
Consider whether all elements behave the same way under stress.
Design a simple two-dimensional frame and apply the Direct Stiffness Method to determine its displacements when subjected to a given load.
Follow the structured steps above.
Given a bending moment applied to a beam in a frame, calculate the resulting displacement using stiffness matrices.
Remember to consider the beam's properties in your calculations.
