As a method of seismic-design for pile-supported wharves, equivalent static analysis, response spectrum analysis, and time history analysis method are applied. Among them, the response spectrum analysis is widely used to obtain the maximum response of a structure. Because the ground is not modeled i...

응답스펙트럼 해석법이란 무엇인가? | 또한 기준서에서는 잔교식 안벽 내진설계 시 응답스펙트럼 해석을 사용하도록 제시하고 있다. 응답스펙트럼 해석법은 응답스펙트럼 곡선을 통해 구조물의 고유모드에 따른 최대 응답을 산정하는 탄성해석 기법이다[15]. 본 기법은 해석의 간편함과 더불어 모드 조합법을 통해 다수의 모드를 고려할 수 있어 종래부터 교량 및 구조물 등에 널리 사용되어 왔다[16, 17]. | |
국제해운협회에서 제시하는 구조물 수치해석 기법은 무엇이 있는가? | 잔교식 안벽과 같은 항만 구조물의 경우 실제 크기의 실물 시험이 어려우므로 수치해석기법을 이용하여 내진성능을 평가할 수 있다. 국제해운협회(International Navigation Associate)의 Seismic Design Guideline for Port Structures(이하 PIANC)[1]에서는 잔교식 구조물의 수치해석 기법으로 push-over 해석법, 응답스펙트럼 해석법, 그리고 FEM/FDM(시간이력해석법) 등을 제시하고 있으며, 해양수산부 항만 및 어항시설의 내진설계 표준서(이하 MOF)[2]에서는 응답스펙트럼법, 그리고 시간이력해석법 등을 제시하고 있다. 이 중 push-over 해석법은 구조물의 비선형 해석을 통해 지진 하중에 대한 구조물의 보유 성능을 평가하는 비선형 정적 해석 기법으로, 항복점 도출 및 구조물의 안정성 평가를 위해 본 해석이 사용되고 있다[3-6]. | |
잔교식 구조물의 수치해석 기법 중 push over 해석법의 특징은 무엇인가? | 국제해운협회(International Navigation Associate)의 Seismic Design Guideline for Port Structures(이하 PIANC)[1]에서는 잔교식 구조물의 수치해석 기법으로 push-over 해석법, 응답스펙트럼 해석법, 그리고 FEM/FDM(시간이력해석법) 등을 제시하고 있으며, 해양수산부 항만 및 어항시설의 내진설계 표준서(이하 MOF)[2]에서는 응답스펙트럼법, 그리고 시간이력해석법 등을 제시하고 있다. 이 중 push-over 해석법은 구조물의 비선형 해석을 통해 지진 하중에 대한 구조물의 보유 성능을 평가하는 비선형 정적 해석 기법으로, 항복점 도출 및 구조물의 안정성 평가를 위해 본 해석이 사용되고 있다[3-6]. 2차원 시간이력해석은 중요도가 높은 구조물에 적용되며, 다른 해석 기법에 비해 높은 정확도를 가지므로 민감도 분석 및 취약도(fragility)분석 등에서 널리 사용되어 왔다[7-12]. |
