Bispec makes it extremely easy to compute constant-ductility spectra and constant-strength spectra, for an Earthquake ground motion record, or to compute spectra and statistics (mean, standard deviation, etc.) for a suite of ground motions.

The program is available free to "Nisee e-library" members (membership costs $25 a year)."; function tShowHide(id, show) { var s = document.getElementById("desc"); if ((s.innerHTML.length<=212 || show==1) && show!=2) { s.innerHTML = fDesc[id]; if (document.getElementById('m1')) document.getElementById('m1').style.display='none'; if (document.getElementById('m2')) document.getElementById('m2').style.display='none'; if (document.getElementById('more_txt')) document.getElementById('more_txt').style.display='inline'; } else { s.innerHTML = ''; } }
