Given a structure with a mass of 5000 kg and a damping coefficient of 10 Ns/m, derive the equation of motion including the stiffness multiplier and ground acceleration of 5 m/s².
💡 Hint: Remember to keep each term consistent with units and parameters.
Assume a building uses time history analysis to evaluate responses to a ground motion with varying acceleration over time. Discuss its impact relative to a simple average response from response spectrum analysis.
💡 Hint: Think about the detailed aspect of how structures react as conditions change.
