Abstract
The State of the Art of Ground Motions Selection and Modification Methods for Response History Analysis
Highlights
There are three well-used methods for evaluating structural responses under the seismic excitation - Equivalent static analysis, modal response spectrum analysis, response(time) history analysis (RHA)
Equivalent static analysis and modal response spectrum analysis have been more widely used than RHA, since they have relatively simple process to evaluate the performances of structure
The objective of this paper is to introduce the state of the art of ground motions selection and modification methods (GMSM) for RHA

Submission: February 06, 2018; Published: March 19, 2018 *Corresponding author: Seong Jin Ha, Korea National University of Transportation, Choungju, South Korea, 27469, Tel: 82+43-841-5200, Email:. The ground motions selection and modification is one of the most important process in whole procedure of seismic design or performance evaluation of structures. The purpose of the opinion paper is to introduce the trends in the ground motions selection and modification methods for response history analysis. Monte-carlo simulation based approaches to consider ground motion correlation have been developed in recent year. Benefits, limitations, and alternatives to the methods are given
