Recently, measures for reducing noise and vibration of a railroad station are actively being developed to enhance its property value and comfort level of passengers. In this paper, the applicability of the recently developed vibration mitigation method utilizing a platform TMD (Tuned Mass Damper) by installing a spring-damper system beneath the platform is experimentally verified using a bench scale structure. The two-story bench scale structure is built to simulate a real railroad station, and vibration reduction effect is verified by comparing acceleration before and after applying the platform TMD at the 2nd floor of the structure. The design parameters of the platform TMD system is determined based on vibration analysis result and the MTMD (Multiple TMD) theory recently developed to enhance the effectiveness of the platform TMD method. The vibration is excited to the bench-scale structure using a vibrator. The performance test result for a spring-damper system is also presented. The result of the experiment reveals that the platform TMD method can reduce the vibration of the bench-scale structure by greater than 5dB(V).

This paper analyses the railroad trunk line constructed in the Korea since the end of the 19th century. The analysis consists of the following problematics. 1) The process of the decision of the railroad route 2) The relationship of the location of Eupchi and the stations By clarifying the above, the purpose of this paper is to clarify how the morphology of the city in Korea has been affected by the change in the relationship with Korea and Japan. The Empire of Japan has been reconnoitering the Korea since way before the formal contract for the railroad construction was signed. Therefore, the Empire of Japan had a very good understanding of the actual transportation system when it started the construction of the railroad. The railroad construction was used by the Empire of Japan to empower the control over the Korea. For this reason, the new railroad system was constructed as a different system from the former transportation system and the urban system was also affected. Also the relationship of the western powers and Japan around the turn of the 20th century defined the characteristic of the railway system as a pathway through the Korean peninsular to link Japan to the continent. Moreover, being apprehensive about the friction with the western, Japan located the railway stations to avoid the missionary land properties. This made it clear that the restraint relationship between Japan and the western affected the urban special structure.

The Industrial Revolution brought a variety of new forms of structure, and as a group they are usually called 'industrial architecture'. Steam engines contributed greatly to architecture with a unique structure called 'water tower' to provide water for steam engines, especially the adoption of it. This study is to examine the changes of the building materials and architectural features of the water towers of railway stations built in the early twentieth century in South Korea. This study also attempts to describe the modern features of the industrial architecture, which did not get a chance to be noticed. Through this examination on water tower, which is a part of industrial architecture with sheer integration of function and pure geometric form, we would like to find the meaning of modern architecture in Korea. As we can see in the Korean oldest railway station water tower constructed in masonry at Yeonsan Station in 1911, early water towers were divided into the masonry machine room and the steel water tank. However, the masonry structure was soon turned into concrete structure with its formal features maintained as it was. The steel water tank was also replaced with concrete structure. As a result, while its basic structure remained, concrete structure had substituted for the every components of water tower. Concrete-built water towers were the high-tech architecture of that time and the most perfect structures built in concrete. Nevertheless, the perfection of the water tower form and the technology it attained were not transferred to other modern and contemporary architecture in South Korea. Since the subject to railway station water towers was the Japanese government, and steam engines were replaced with diesels in the midst of a complicated domestic situation after the independence, the need for water towers in railway stations disappeared and therefore, it became ignored and was difficult to look over the architectural features and values of early railway station water towers.

In this thesis, the Development of Station Buildigs Design during last a hundred years in Korea is analyzed. From the early time to today, several posts of Office of Korean National Railroads have controlled the Station Buildings Design by Standard Drawings. Sometimes, private architects joined in designing the Stations, that have the value as historic architecture. Under the Japanese imperialistic rule, Japanese Officer designed all of the stations ; that can be classified 1) wooden compromise style, 2) renaissance style, 3) northern European house style, 4) general station by standard drawing, 5) Korean house style. 6) modernism style. Especially, Korean house style was not planned to commemorate the old Korean Architecture, but to beguile the Japanese tourists' monotony of the journey in Korea. After the Independence, the Station Buildings are grouped into 1) international style, 2) modernism style with traditional details, 3) Station Complex Buildings. In the future, design of the Railroad Station Building needs to be diversified to satisfy tourists' emotion.

최근 철도에서 주거지역, 상가와 같은 외부로 전달되는 소음으로 인한 피해를 줄이기 위해, 일반적으로 도로변에 방음벽을 설치하는 것과 같이 외부에 전파되는 소음을 차단하는 대책이 적용되고 있다. 반면, 역사 플랫폼에서 열차 정차 및 통과로 인해 발생하는 진동 및 소음공해는 탑승을 위해 대기 중인 승객들에게 그대로 전달되고 있는 실정이며, 이는 대기 중인 승객들에게 다소 불쾌감과 거부감을 줄 수도 있다. 이 논문에서는 지상역사에서 플랫폼에 전달되는 소음을 저감하기 위해 흡음형, 간섭형, 공명형과 같은 여러 방음벽에 사용하고 있는 구조들을 플랫폼 단부에 설치하는 방안을 제시하고 이와 관련된 구조해석 검토를 수행하여 결과를 제시하였다. 각 경우의 플랫폼에 대한 소음해석은 VIRTUAL LAB을 이용하여 수행하였다.

철도 역사의 경우 보다 효율적인 진동 저감 대책 수립을 위해서는 열차-궤도, 궤도-구조물 등의 상호작용 및 진동의 전달 경로에 대한 고려 등이 필요하다. 또한 역사 구조물의 경우도 접속 교량과의 상호작용, 승강장, 지붕 등 부대시설과의 상호작용에 대한 고려도 필요할 수 있다. 그러나 이러한 역사 구조물과 부대시설과의 상호작용이 소음 및 진동에 미치는 영향에 대한 연구는 미미한 실정이다. 이 논문에서는 승강장과 역사 구조물간의 상호작용 분석을 통하여 소음과 진동을 저감시키는 방안에 대한 연구를 수행하였다. 특히 승강장과 역사 구조물간 연결부의 강성 및 감쇠에 대한 조절을 통한 역사 구조물의 진동 저감 가능성을 검토하였다. 진동 저감 성능은 2차원 및 3차원 유한요소 모델을 이용하여 검증하였다.

The schedule speed is one of the most important elements of railway industry. In korea, Gyeongbu Line’s highest speed is 300km/h. But it’s schedule-speed is no more than about 174km/h from Seoul to Busan. In this study, we analyzed the effect of the proposed improvements in the speed reduction zone using Train Performance Simulation. We found that the improvements can raise the schedule speed from 15 to 20%.
