1. Input File Name C Program Files RspMatchEDT Output RspMatch defaultSE Tin Working Folder C Program Files RspMatchEDT Output RspMatch This form is used to generate a target spectrum in the correct format for use with the spectral matching program RspMatch The code used is based on the code for the SETARGET program developed by Dr Norman Abrahamson The user must supply a set of spectral values between which the target spectra will be generated based on equal log spacing The input spectral acceleration values should be in units of g for use in the RspMatch code but the SETARGET code can interpolate on any units The definition for each variable used in the SETARGET computer program used in this section was literally copied from the documentation included with the RspMatch program by Dr Norman Abrahamson 1998 for Version 5 22 97 2 2b The following input files are needed to run the code the variable names as described in the original documentation are shown in bold font and the corresponding labels used in the RspMatchEDT program are shown in Italic bold font filein Target Spectrum File File which contains the initial target spectral values for 5 damping The file can be created using the Target command button to obtain spectra from design codes or attenuation relations This file must be in the following format see example input file at the end of this section Title 80 characters in length Npe
