Abstract

The purpose of this research is to introduce the simplified equivalent frame model for the equivalent lateral force procedure, the response spectrum procedure and nonlinear procedure according to ASCE7-10 in order to reduce the time of performance and reasonably evaluate the effect of applying the damping system with the various conditions for the analysis and the variable. In this research, the seismic performance assessment and the design of the damping system were conducted through the nonlinear time history analysis based on the performance based seismic design in ASCE7-10 in regard to applying the damping system to apartment buildings which is lately issued. The optimal design based on the 75% of seismic base shear was performed for an apartment building. The seismic performance assessment were conducted to check the safety of the building, and the economic evaluation was performed by comparing the amount of resource for the optimal designed building with the amount of resource for the original building. In addition, hysteresis dampers was applied to the apartment building, and the suggested equivalent frame model was performed using the damping system design in ASCE7-10, then its control effects were proved in the full scale model of the apartment building which was used in this research.

이 연구의 목적은 감쇠시스템 설계 시 ASCE7-10의 등가선형해석과 응답스펙트럼해석의 설계절차 및 비선형해석에 간략화된 등가프레임모델을 제안하여, 선형 및 비선형 해석 시 소모되는 시간을 줄이고 해석 조건 및 변수조건을 다양화함으로 감쇠시스템 적용 시 효과를 합리적으로 검토하는데 있다. 이 연구에서는 최근에 이슈화 되고 있는 공동주택의 감쇠시스템 도입과 관련하여 ASCE7-10의 성능기반 내진설계를 근간으로 내진성능평가 및 감쇠시스템 설계를 비선형응답이력 해석을 통하여 수행하였다. 특히 공동주택 대상건물을 건축구조기준의 75% 지진력 수준으로 최적화 설계 시 내진성능평가를 수행하여 안전성을 검토하는 한편, 기준에 제시된 지진력 수준으로 내진설계 시 골조물량을 비교 하여 경제성을 검토하였다. 또한, 대상건물에 외부제어 이력형 감쇠장치를 적용 시 제안한 프레임 등가모델을 이용하여 ASCE7-10 감쇠시스템 설계를 수행하였으며 Full Scale Model에서 그 제어효과를 검증하였다.
