The majorĮquipment in the LESS includes a uniaxial seismic simulator (commonly called a shake table), two 3 kips The last line in the code saves the FLAC model and all output as a file called. State-of-the-art facility for simulating earthquakes and the effects on small scale structures. According to the recorded ground accelerations, the ground velocity and displacement have been obtained by integrations, baseline corrections, and band-pass filtering (Butterworth type, with cutoff frequency in the range of 0.2, 20 Hz Chang & Taboada, 2009) via the software SeismoSignal (Seismosoft, 2017), as shown in Figure 4. The program is able to read accelerograms defined in both single- and multiple-values per line formats (the two most popular formats used by strong-motion databases), and can apply baseline correction and filtering prior to time-integration of the signal (to obtain velocity and displacement time-histories).Western Michigan University’s Laboratory of Earthquake and Structural Simulation (LESS) is located at C113 in the College of Engineering and Applied Sciences (CEAS) building in Kalamazoo, Michigan. Three different digital filter types are available, all of which capable of carrying out highpass, lowpass, bandpass and bandstop filtering. SeismoSignal also enables the filtering of unwanted frequency content of the given signal.
