Abstract

Irregularity in structural shape is a ubiquitous phenomenon. Structural hazards evoked from irregularity need to be checked against extreme lateral loadings. Structures containing four distinct types of irregularities in terms of continuity and discontinuity in upper half-length and all story levels along with O-shape are investigated. The structures were analyzed numerically and different seismic responses such as displacements, bending moment, axial forces, torsions, story drift, etc. were scrutinized. The seismic and wind load analysis was conducted for ACI 318-11 conditions. Results show that buildings having discontinuous beams on the upper half exhibit better resilience. It is also concluded that O-shaped building structures provide better resistance to overturning, making this shape relatively safe.

구조물의 비정형성이 풍하중과 지진하중을 받는 구조물의 안전성에 미치는 영향에 대해 검토하였다. 층별 보부재의 불연속성과 O자형 수평비정형성의 관점에서 4가지 유형의 구조물을 선정하여 구조거동을 평가하였다. ACI 318-11 조건에 대해 풍하중 및 지진하중에 의한 구조물의 변위, 휨모멘트, 축력, 비틀림, 층간변위 응답을 검토하였다. 보부재 불연속성을 갖는 구조물의 상부에 갖는 건물이 가장 큰 복원력을 보였으며, O자형 수평비정형 건물은 전도에 대한 저항이 크므로 횡하중에 대해 안전하였다.
