Demonstration Programs

These demonstration programs show the major portion of computations that can be accomplished by the programs downloaded from here. These programs have been written in the basic frame of Windows95. Some of the menu items have been grayed because the input data and output file names cannot be changed.

The Ground Motion Time history Properties program reads the acceleration data from an ASCII file (including its sampling interval), and derives the velocity and displacement time histories of the corresponding ground motion. The program then goes to compute the response spectrum and power spectral density of the earthquake ground motion. Peak values of the ground acceleration, velocity and displacement and some other statistical properties of the ground motion can be displayed in the program window. displayed.

Spectrum compatible accelerograms are require in engineering design. The basic input to this program is a response spectrum shape placed in an ASCII file. The program generates any number of accelerograms, whose response spectrum matches with the input response spectrum. Spectrum matching of the synthesized accelerogram can be displayed in the program window. For more details on the procedure for synthesizing the accelerogram click here.
