Abstract

Because of earthquakes that have recently struck, seismic design criteria that considered performance of structure were included in the design concepts. Thus, a simple analysis tool is needed to predict the strength and ductility of RC structures. In this study, three-dimensional lattice model was developed to expand the two-dimensional lattice model. Torsional analysis of the structure was done to evaluate the developed three-dimensional lattice model. Lattice model was evaluated by comparing analytical results with experimental results. Lattice element size was evaluated using the results of analysis. Torsional analysis results, using three-dimensional lattice model, show that the results are relatively consistent with the experimental values.

최근의 지진을 경험하면서 지진에 대한 성능 설계 개념이 설계기준에 포함되기 시작하였다. 따라서 RC 구조물의 강도와 연성을 예측할 수 있는 간단한 해석도구가 필요하다. 이 연구에서는 2차원 래티스 모델을 확장하여 3차원 래티스 모델을 개발하였다. 개발된 3차원 래티스 모델을 평가하기 위하여 구조물의 비틀림 해석을 수행하였다. 해석의 평가를 위하여 실험 결과와 비교하였다. 래티스 요소의 크기에 따른 해석 결과를 분석하여 사용성을 검토하였다. 개발한 3차원 래티스 모델을 사용한 비틀림 거동해석이 실험값과 비교적 일치하는 결과를 보여주었다.
