프리캐스트 콘크리트 복개아치구조물은 콘크리트 구조물의 프리캐스트 상점과 아치구조물의 구조역학적 장점을 효과적으로 결합한 구조물이다. 본구조물은 단면이 얇은 관계로 지반-구조물 상호작용 효과를 고려해야 한다. 그러나 상재하중의 증가시 상호작용 효과가 실질적으로 발생되지 않는 경우가 있다. 본연구에서는 상재하중에 의한 구조물의 강성변화시 수치해석 방법들의 적용기준에 대한 방법론을 제시하였다. The precast concrete arch using the open-cut method combinates two structure, that is the arch and the precast concrete. Because the precast concrete arch is slender, the soil-structure interaction has to be considered in the method of analysis. But when the loads .acting on the structure is overloaded, the soil-structure interaction analysis might be unuseful. In the study, three .numerical analyses are used and the information for determining the design load is obtained from these outputs.

Purpose : To investigate the relationship between 3D bone architectural parameters and direction-related elastic moduli of cancellous bone of mandibular condyle. Materials and Methods : Two micro-pigs (Micro-pig^(R), PWG Genetics Korea) were used. Each pig was about 12 months old and weighing around 44 kg. 31 cylindrical bone specimen were obtained from cancellous bone of condyles for 3D analysis and measured by micro-computed tomography. Six parameters were trabecular thickness (Tb.Th), bone specific surface (BS/BV), percent bone volume (BV/TV), structure model index (SMI), degree of anisotropy (DA) and 3-dimensional fractal dimension (3DFD). Elastic moduli of three orthogonal directions (superiorinferior (SI), medial-lateral (ML), andterior-posterior (AP) direction) were calculated through finite element analysis. Results : Elastic modulus of superior-inferior direction was higher than those of other directions. Elastic moduli of 3 orthogonal directions showed different correlation with 3D architectural parameters. Elastic moduli of SI and ML directions showed significant strong to moderate correlation with BV/TV, SMI and 3DFD. Conclusion : Elastic modulus of cancellous bone of pig mandibular condyle was highest in the SI direction and it was supposed that the change into plate-like structure of trabeculae was mainly affected by increase of trabeculae of SI and ML directions.
