This article presents a critical analvsis of the recommendations for time-history analvsis contained in the Chilean standard for seismic design of industrial facilities (NCh 2369 Of2004). For this purpose, a method for the selection of carthquake records to be used in time-history analysis is presented. In addition, this article presents the results of a comparative study of the record scaling methods proposed by the European, North American, and New Zealand standards. The differences between these methods and their effects on the structural response of a single degree of freedom system are identified. Some recommendations to improve the Chilean standardare obtained from these studies.
