  • 고층건물의 사용성설계는 가속도와 같은 풍응답진동에 의하여 자주 영향을 받으므로, 이때 고유진동수의 올바른 산정은 중요하다. 설계단계에서 사용되고 있는 이러한 진동수 경험식들은 상호간에 서로 다른 결과치를 제시하는 경향이 있다. 이 논문은 철골조 건물의 진동주기에 대한 것으로서, 건물의 진동실험방법과 상시진동실험에서 얻은 고유주기를 예측하기 위한 방법을 제시하였다. 서울지역 21개동의 상시진동 계측데이터에서 고유주기를 산정하였다. 철골조 고층건물의 고유주기 근사식을 제안하였으며, 고유주기의 근사식을 국내외 기준 및 고유치해석의 결과와 비교하였다.

  • When the natural villages in Jeju province are incorporated into the district of city planning, they are considered to be a small-scale residential districts. Therefore, a garden city should be planned that considers the characteristics of the villages to implement an appropriate street system, to use the area effectively, and to harmonize the villages with the surrounding communities. There have been an especially large number of problems with the street system in the city of Seogwipo, which was notified as the area of natural settlement. This study analyzes the problems inherent in street planning and the present condition of roads whose construction has been postponed for a long time due to several problems including an inappropriately planned street system. Based on the research of various documents, a practical street system has been investigated. Most of the residents in natural settlement units demand use of the continued the existing roads as well as the implementation of an effective street system. They ask for street planning under which the involved construction would take only a short period of time and would result in only minimal damage to their existing properties. Therefore, the street system should be planned so as to preserve the nature-friendly features of natural settlements, their surroundings and tourism resources. Even after streets hwve been planned and their completion you has been established, the plan should be continuously evaluated, analyzed and compared with other alternatives. The street plan should continuously incorporate improvement measures which would satisfy various aspects of the street system including land use, traffic demand, and future population demands. Both the amount of money to be invested and economical efficiency should be considered for street planning since the street system has a great impact on many industries. Unnecessary costs related to excessive road construction should be avoided. The street network plan should also include the complete evaluation of the natural topography as well as the surrounding. Considering these views, the data concerning the current condition of the city and the related investigation play an important role in establishing a street plan. However, the investigation of future construction plans by the city is as of yet at a very early stage. Therefore, there is an urgent need for the investigational study of the current city development plans. The street system for the natural settlement area should be established only after the thorough investigation of all aspects of street planning. In addition, the plan should be flexible enough to consider the characteristics of Jeju.

  • 우리나라 건설시장의 침체로 해외 건설시장을 개척하고 동시에 부족한 자원 확보의 필요성이 제기되고 있다. 이에 본 연구는 최근 아프리카 국가 중 정치경제적 성장가능성을 인정받고 있는 콩고민주공화국 건설시장 현황을 파악하고 우리나라 건설업체의 효과적인 진출방안을 모색하는 것을 목적으로 하였다. 본 연구를 위하여 문헌연구와 콩고민주공화국 현지 방문조사를 수행하였으며 결론은 다음과 같다. 콩고민주공화국은 독재로 인한 정치적 불안정성과 전쟁으로 인한 저개발로 인해 도로, 철도, 항만, 공항 등 다양한 인프라 투자를 필요로 하고 있다. 콩고민주공화국에 진출할 경우 투자비 회수의 안정성, 단계적 건설의 가능성과 건설된 인프라의 이용가능성, 공기와 투자비 회수의 선순환 등 여러 가지 조건을 고려해야 하는데, 이를 충족하는 인프라유형은 도로 분야로 판단된다. 콩고민주공화국 정부의 부족한 재정과 풍부한 자원을 고려할 때, 도로 건설에 소요되는 투자비와 이윤을 회수하는 방식은 인프라 건설과 자원을 교환하는 패키지딜 방식이 가장 적합하다.

  • There is growing consciousness of the environmental performance of buildings in Hong Kong. The Buildings Department, the Lands Department and the Planning Department of the Hong Kong Government issued the first of a series of joint practice notes [1] to promote the construction of green and innovative buildings. Green features are architectural features used to mitigate migration of noise and various air-borne pollutants and to moderate the transport of heat, air and transmission of daylight from outside to indoor environment in an advantageous way. This joint practice note sets out the incentives to encourage the industry in Hong Kong to incorporate the use of green features in building development. The use of green features in building design not only improves the environmental quality, but also reduces the consumption of non-renewable energy used in active control of indoor environment. Larger window openings in the walls of a building may provide better natural ventilation. However, it also increases the penetration of direct solar radiation into indoor environment. The use of wing wall, one of the green features, is an alternative to create effective natural ventilation. This paper therefore presents a preliminary numerical study of its ventilation performance using Computational Fluid Dynamics (CFD). The numerical results will be compared with the results of the wind tunnel experiments of Givoni.

  • Kengo Kuma is one of the features of the building is 'natural architecture'. He is saying that the construction of the building in which he is seeking is a natural material of construction is only applied to the issue as to whether the material nature, but that the relationship between humans, the environment, natural point of view in his book. Like repeating units are part of the two hundred ninety-four came mainly small ways to create a relationship, or have architectural features make up the sum of his architecture. I present a comprehensive study is reported in terms of that the 'grain' of such a small part of the unit, according to the architecture of Kengo Kuma mainly granulation characteristics of the construction of one of the practical expression studies Kengo Kuma. Is represented as louvers, check pattern, hole, granulation unit such trend, but have become developed in other directions such simple types are combined. Analysis and particle characteristics in terms of the architectural space of Kengo Kuma, serve as the purpose of the present study reveal that each of the features that have a meaning in the construction of any Kengo Kuma.
