Program: SIMQKE-II Title: Conditioned Earthquake Ground Motion Simulator Developer: E.H. Vanmarcke, Department of Civil Engineering and Operations Research, Princeton University; G.A. Fenton, Department of Applied Mathematics, Technical University of Nova Scotia, Halifax, Nova Scotia, Canada; and E. Heredia, Instituto de Ingenieria, Universidad Autonoma de Mexico, Coyoacan, Mexico DF, 1997. Category: Strong Motion Data Processing Platform: DEC, Unix, f77; Sun, Solaris, f77; SGI, IRIX, (fortran not known); HP, UX, (fortran not known); PC, Linux, (fortran not known) Reference: Vanmarcke, E.H., G.A. Fenton, and E. Heredia-Zavoni, "SIMQKE-II, Conditioned Earthquake Ground Motion Simulator, User's Manual, Version 2." Princeton University, Princeton, New Jersey, February, 1997. Summary: The program SIMQKE-II was designed with the aim of producing realistic earthquake ground motion simulations over both space and time for structural design purposes and to allow those simulations to be consistent with observed data, if any. The simulation of ground motions at a number of spatial locations, where these motions are properly intercorrelated, involves the user specifying the following information. 1)target spectral density function: this function is prescribed discretely and may be evolutionary to account properly for the changing nature of earthquake motion during an event. 2)where simulation at more than one spatial point is desired and/or the simulation is to be conditioned on known records, the relative spatial coordinates of the simulation and recording points must be provided. 3)the functional form of the space-frequency correlation function needs to be selected: at present, two such functions are provided in the distribution, one employing an exponentially decaying correlation, the other using a logarithmic form. These functions are modular so that users can easily add functions of their own liking to the source code. 4)parameters of the space-frequency correlation function. 5)known ground motion records, if any. The program employs sophisticated space-time random field theory to efficiently produce a realistic field of conditioned or unconditioned evolutionary ground motions that represent one possible realization of an earthquake event at a set of spatial points. The generated motions match the target spectrum on average. A sequence of these events can then be used as input to evaluate probabilistically the dynamic performance of extended geotechnical, structural, or mechanical systems. The dynamic response under each event can be computed using any good deterministic analysis package. The raw simulation is performed using Covariance Matrix Decomposition in the frequency domain. If the simulations are to be conditioned, the raw, or unconditioned, simulation is followed by a Best Linear Unbiased Estimation technique, also in the frequency domain. Finally, a Fast Fourier Transform (FFT) is applied to produce the simulated output ground motions. The time histories are output to a file in ASCII form and so are easily readable by any other post-processing program. The option is provided to produce plots of the time histories or spectral density functions via PLOTPS format output files. These files need to be processed by a program called plotps, written by Gordon Fenton, and available on this CDROM to produce PostScript (TM) output files. These can then be printed on a PostScript printer or previewed on a screen using, for example, the GNU program ghostscript (available at prep.ai.mit.edu) or any other PostScript interpreter. The source code is written in standard Fortran 77 with Makefiles provided for a variety of operating systems: DEC UNIX, Sun Solaris, SGI IRIX, HP-UX, and Linux. There are a number of intrinsic BSD 3F functions that may not be supported on all operating systems. These functions are: getpid(), getarg (i,str), iargc (), and fdate (str). See the User's Manual for more details. The code has been successfully compiled and run on most UNIX machines having FORTRAN 77 which supports the above BSD 3F functions. The User's Manual explains what must be done to compile the program on machines which do not have the above support.
