Earthquake Response Spectrum Analysis Using MATLAB

I found an old assignment from a long time ago in the trash bin… This is a frequency-time hybrid algorithm based on the Newmark-β implicit integration method, utilizing the Piecewise Exact Method (PEM) to perform batch calculations of the elastic response spectrum for a single degree of freedom (SDOF) system under seismic excitation. The seismic … Read more

Modal Decomposition Response Spectrum Method in MATLAB

The “Code for Seismic Design of Buildings” GB50011-2016, Section 5.2.2: When using the modal decomposition response spectrum method…Advantages and Disadvantages: The modal decomposition response spectrum method, in simple terms, imagines a multi-story building as several “independent pendulums,” each corresponding to a natural vibration period and mode shape. First, the maximum seismic force for each pendulum … Read more
