Dynamic Response of a Single Degree of Freedom (SDOF) System Under Earthquake Effects Based on Matlab

The dynamic response of a Single Degree of Freedom (SDOF) system under earthquake effects based on Matlab. The displacement, velocity, and acceleration responses of the structure are calculated using two numerical integration methods (central difference method and Newmark method), and the results of these two methods are compared. Earthquake acceleration time history data is imported. … Read more
