SPECTIME:

Response Spectrum Compatible Time History Generator

Shake table users and other seismic researchers often need to develop one or more statistically independent time histories that have a specified response spectrum.  ANCO offers a program, SPECTIME, which produces a text file spectrum compatible time history for use in shake table drivers or analysis programs.  Some of the program attributes are:

• Fast: Iteration takes only seconds.
• Convenient:  Outputs response spectrum and time history in easily read text files specifying acceleration, velocity, and displacement time histories and plots.
• Accurate:  Typically matches spectrum to within 10% or better
• Instructive:  All processes presented and visualized in one GUI window.
• Reduces Test Time:  Quickly meet IEEE-344 multi-axes stationary/independence (see IEEE-344 Check ANCO software).
• SPECTIME is a PC-based, ANCO written Virtual Instrument (VI) using LabVIEW.
• Uses the Gasparini and Van Mark algorithm.
