SIMQKE-II program can readily generate conditional or unconditional spatially correlated earthquake ground motions which can be used as the input profile for multi-support excitation analysis of large structures (such as long-span bridges , power transmission systems or some extended structures). I downloaded this program from Berkeley achieve and followed the "readme" file to run it, but it doesn't work correctly in Windows XP or later versions. I wonder if someone have such experience to show me the way out, Thank u.
