With the more sophisticated computer programs now available for the dynamic analysis of structures, use of time-history excitation of such structures has become common practice. Besides affording a more rigorous analysis of the structure itself, a time-history excitation simplifies the calculation of the response of equipment located at the higher elevations in a structure. Regarding the time-history excitation of a structure, the main problem would be the selection of an accelerogram that is compatible with a given smooth spectrum curve. A method to obtain a comaptible accelerogram is discussed herein.
