구조물이 안전성을 확보키 위해서는 외력의 불확정성 이외에 실제의 구조물이 해석을 위해 이상화되는 모델과는 다르게 되어 있으므로 구조물의 불확실성을 고려해야 한다. 실제로 유한요소해석시 구조물의 해석모델은 과거의 경험이나 공학적 판단에 기초하여 여러가지 구조물의 불확정성요소에 관계없이 이상화되어 최악의 경우에는 사고에 관계가 없다고 보증할 수 없는 것이다. 더욱이 최근에는 장대교량, 초대형건축물 및 원자력발전소와 같은 중요한 구조물이 증가추세에 있으며 그들의 예기치 못할 사고위험성에 민감하게 느끼고 있는 우리의 현실에 구조물의 불확정성에 관계되는 연구 또는 외력에 대한 경우와 마찬가지로 많은 연구가 필요하리라 생각된다. 본 고는 불확정 구조계의 확률유한요소해석에 관해서 참고문헌[1]을 참조하여 기본개념 및 간단한 예제를 기술하였다.

It is now possible to design buildings in various forms using a diagrid structural system, which is the one of the most useful structural systems. It is difficult to design and construct the connections, however, and the bucklings in braces weaken the seismic performance of structures. In this study, the initial stiffness, ductility, and energy-dissipated capacity of a diagrid and a diagrid BRB were evaluated via frame tests. The results of the cycling load tests showed that the diagrid BRB had better initial stiffness and ductility, and dissipated extra energy after the BRBs were yielded.

The expected demands for the new styling design can be studied by examining the recent deliveries and the new buildings on order. These ships are setting the trend for the operation of passenger ships. There has been a rapid increase in size and produce of ship some remarkable exterior design image. These ships follow very similar design concept, even if their operator compete with each other in the same market. But also new innovative design solution have been introduced to catch the interest of the passengers. The propose of this study is to investigate the exterior styling design in passenger ships, which result form examining the exterior elements such as funnels, pods, hulls, trademark, colours, flowing curvilinear lines and from. Each different passenger ship lines require different design style for different markets, while ships of different sizes and categories obviously require different solution. When a new class is created later, key design element will be retained, with some items being changed and new ideas introduced.
