Abstract

Recently, significant progress has been made in performance-based engineering methods that rely mainly on nonlinear static seismic analysis procedures. The Capacity Spectrum Method (CSM) and the Displacement Coefficient Method (DCM) are the representative nonlinear static seismic analysis procedures. In order to evaluate the applicability of the procedures to the seismic evaluation and design process of new and existing structures, the accuracy of both CSM and DCM should be evaluated in advance. The accuracy of seismic responses by the nonlinear static procedures is evaluated in comparison with the shaking table test results for the structural wall specimen subjected to the far field and near field earthquakes. Also conducted are comparative studies where the shaking table test results are compared with those from nonlinear dynamic analysis procedures, i.e., Single-Degree-of-Freedom (SDOF), equivalent SDOF and Multi-Degree-of-Freedom (MDOF) systems.

근래에 비선형 정적해석법에 기초를 둔 성능-기반 방법이 각광을 받으면서 개선되고 있다. 역량스펙트럼 방법과 변위계수법이 비선형 정적해석법 중에서 대표적이라고 할 수 있다. 새로 건설되거나 기존의 구조물에 대하여 내진설계와 내진성능 평가에 대한 비선형 정적해석법의 적용성을 평가하기 위해서는 우선적으로 역량스펙트럼 방법과 변위계수법의 정확성이 평가되어야 한다. 비선형 정적해석법의 정확성은 근거리 및 원거리 지진하중에 대한 철근 콘크리트 벽체 구조물의 진동대 실험결과와 비교하여 평가하였다. 또한, 단자유도계, 등가단자유도계와 다자유도계에 대한 비선형 동적해석기법에 의해 평가된 지진응답도 진동대 실험결과와 비교하여 평가하였다.
