Problem 2

Implement the central difference method (CDM) to solve vibration problems for linearly elastic

viscously-damped SDF systems following Module 3, Slide 11. Chopra, Table 5.3.1 outlines the

step-by-step procedure you may follow. Make sure your spreadsheet/code can plot the force as

well as response quantities such as displacement, velocity, etc.

To validate your code, solve Chopra, Example 5.2 and compare your results with Chopra, Table

E5.2. Your output, ti vs. u should be identical.

Check the three requirements per Module 3, Slide 10!
