Procedure for selecting and modifying earthquake motions to multiple intensity measures

摘要

A new ground motion selection and modification procedure is presented that selects a set of ground motions to capture multiple intensity measure targets. The ground motion selection and modification procedure involves selecting a set of candidate ground motions scaled to a conditioning intensity measure that is subsequently trimmed down using a semi-automated selection process to reach a final set that satisfies statistical considerations. The new procedure is relatively straightforward to implement using common tools and knowledge yet is still based on the principles of conditioning and on aspects of previously-developed selection and modification procedures. A single example is provided to demonstrate the use of these concepts to ground motion development. (C) 2016 Elsevier Ltd. All rights reserved.
