'최근 고층건물 설계 시 내진설계와 내풍설계의 부조화 문제를 해결하기 위해 성능기반 내풍설계에 대한 연구가 활발히 진행되고 있다. 이 연구에서는 개정 예정인 국내 설계기준(KDS 41)을 기반으로 성능기반 내풍설계를 위한 풍하중 재해도와 비탄성 거동을 허용하는 성능목표를 제시하였다. 비탄성 내풍설계를 위한 반응수정계수 RWR 산정 시 여러 제한 사항들을 고려하여 그 범위를 제안하였으며, 비선형 풍하중 시간이력해석 시 고려해야 할 사항들을 고찰하였다.

Abstract

'Recently, researches on performance-based wind design have been carried out to solve the inconsistency between wind and seismic designs of high-rise buildings. In this study, wind load hazards and corresponding performance objectives that permit inelastic behavior were shown in accordance with Korean Design Standard (KDS 41) draft. The range of response modification factor for inelastic wind design, RWR, was offered considering its application limits. And the considerations to be taken in the nonlinear time history analysis of wind load were discussed.
