MS Excel, MS Word, etc.), noting that the plots characteristics can be fully customised from within the program itself.
#Why are displacements all positive seismosignal full#
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).įinally, and due to its full integration with the Windows environment, SeismoSignal allows for numerical and graphical results to be copied to any Windows application (e.g. Three different digital filter types are available, all of which capable of carrying out highpass, lowpass, bandpass and bandstop filtering.
Effective design acceleration (EDA) Acceleration (ASI) and velocity (VSI) spectrum intensity.Sustained maximum acceleration (SMA) and velocity (SMV).Root-mean-square (RMS) of acceleration, velocity and displacement.Then this information is translated using the seismosignal program into velocity. Cumulative Absolute Velocity (CAV) and Specific Energy Density (SED) In terms of acceleration-time history, responses from all walls are registered.Also the matrix is singular and therefore not invertible. This is a consequence of the symmetry of the forces (equal and opposite to ensure equilibrium).
Arias (Ia) and characteristic (Ic) intensities displacements (or degrees of freedom) and that the two displacements are not independent (that is, the body is continuous and elastic).elastic and constant-ductility inelastic response spectra.SeismoSignal constitutes an easy and efficient way to process strong-motion data, featuring a user-friendly visual interface and being capable of deriving a number of strong-motion parameters often required by engineer seismologists and earthquake engineers.
