Because of the demographic and economic changes and the lifestyle diversification, the new housing types such as the Quasi-housing and urban small-size multi-unit housing are appeared in korea. The current housing use classifications are regulated in accordance with the housing divided ownership, horizontal and vertical size of housing, and the number of units. However, there is a limit to accommodate the new housing type. Therefore, this study proposed the direction of improvement of the housing use classifications through comparative analysis of foreign housing use classifications. Also, building regulations are applied according to the building use classifications. Therefore, the new housing types in building act are very urgent and important. So this study is derived the problems of the current housing use classifications and is proposed the improvement direction of it through the expert opinion survey.

현대사회 건축물들의 고층화로 인하여 구조물의 중량부담 경감의 필요성이 대두되고 있다. 이에 따라 비구조용 재료로 경량기포콘크리트의 수요가 꾸준히 증가하는 추세이다. 다공성 세라믹스(ALC)는 가장 대표적인 경량기포콘크리트로서 경량블록 등의 건축자재로 많이 사용되고 있다. 본 연구는 원료의 입도 및 함량 제어를 통하여 저 고비중 ALC의 물리적 특성을 확인하고자 하였다.

To control vibration of real-size steel structure, a hybrid-type linear motor damper was designed and applied to 30m steel structure at UNISON. The LMD was tuned to the first mode natural frequency of the building. In order to use for simulation data and control parameters, dynamic response characteristics of building and damper were tested. The response of building was reduced by 10 dB with LMD and H$\infty$ algorithm. This value was similar to the result of simulation.

This paper presents the continuous hoop reinforcement method as a means to overcome the difficulty of rebar construction due to the seismic detail of lateral reinforcement. Because the continuous hoop has no seismic hook, and there is less interference during the rebar work, rebar quantities and construction time can be reduced. Since the details of column and beam continuous hoops are different from those of conventional lateral reinforcements, the construction method should be developed through mock-up tests. The length of the beam mock-up is 8m and the section size is $500mm{\times}700mm$, the height of the column mock-up is 2.8m and 4m, and the section size is $800{\times}800mm$. The length and the size are determined based on the elements that are generally used in reinforced concrete basement parking lots and office buildings. The results of the mock-up test showed that the quantities of rebar could be reduced by 20% and the time could be reduced by up to 40% compared with conventional lateral reinforcements.

End of July. 2002 Hyundai Heavy Industries Co. Ltd. Offshore Division is successfully completed Load-out & Float-off work of "AMENAM KPONO/FSO Project" similar to 300K VLCC size. The AMENAM FSO hull and topside module built at the HHI Offshore yard using "On-Ground Building Method" developed by HHI. Various methodologies/techniques like Flexi-built FPSO Hull. Topside module erection method. Load-out Float-off methodology etc. are combined to develop a successful on-ground building method. In this paper, we described the "Hull Structural Strength Analysis Methodology" using 3-D Finite Element Analysis and results. This analysis is performed to verily the structural integrity or the AMENAM FSO hull during the main load-out on two semi-submersible barges combined together.

Fen(分°) is the proportional dimension unit of the standard timber section on Yingzaofashi(營造法式), and there is a phrase that not only structural members but the whole structural design of a building also use Fen as the dimension unit on the book. But in fact only the section dimensions of structural members are recorded by Fen, but the design dimensions are recorded by Chi(尺) on the book. Other historical records also described the building size by Chi. So there has been long-standing debate on the phase in Chinese architectural history society, including the recent confrontation on the analysis of survey figures of the east great hall of Foguangsi temple(佛光寺 東大殿). This paper analyzes all the records about the size of structural members and section planning on the book to make various calculation and evaluation. And it makes a survey of Cai(材) as the dimension and design unit between Chi and Fen through geometric analysis. Cai might be a rough unit of measurement in terms of structural and proportional scheming on Yingzaofashi, and the full size Cai(足材) had been a building scheming module before the Song dynasty.

재실자가 부속실로 피난할 때 부속실 송풍기가 작동하기 전 단계에서는 방화문 개방과 더불어 실내화재로 인한 풍속이 발생하고 화재로 인해 발생된 연소생성물이 부속실을 오염시켜 피난에 어려움을 가져올 수 있다. 스프링클러가 화재풍속에 미치는 영향을 확인하기 위하여 수치해석을 진행하였고 스프링클러의 유무와 분사되는 액적크기에 따른 화재풍속을 비교하였다. 해석은 실제 공동주택의 형상과 치수를 반영해서 진행하였다. 수치해석 결과, 스프링클러가 설치되었을 때 화재풍속이 감소된 것을 확인할 수 있었다. 또한, 액적이 작을수록 화재풍속이 작은 것을 확인할 수 있었다.

The shapes(mass) of buildings are determined by many interrelated factors, such as planning and building regulations, the size and shape of building parcels, and adjoining road conditions. Understanding the effects of the determinants on the building shapes is not a simple task because of the multiplicity and complex interrelationships of the determinants. This study developed a prototype of three dimensional computer model that can simulates the determination process of building shape using GIS and CAD techniques. A commercial block in the south of Seoul was selected for the case study. Several methods of building height control were applied, and their effects on the cityscape were evaluated. The results shows that the three dimensional computer modelling offers an effective means for evaluating the effects of planning and building regulations. The implication of the case study and future research directions were discussed.

Exhaustion of fossil fuels and continued high oil prices, global warming, climate change and to respond to the development and use of alternative energy technologies is expanding rapidly throughout the world. Recently, character of domestic building is appearing by along with economic growth, high-rise, large size, congestion. For this reason, the amount of electrical energy used in a building is increasing. In this study, the applicability of PV modules that are used as roofing and efficiency analysis, and more from the building of BIPV modules built using the activation of alternative energy sources in Korea are aimed want done.
