현대 건축물 및 공공시설물들은 산업 및 건축문화의 발달과 더불어 다기능성 및 편리성에 중점을 두고 설계되어지고 있다. 이런 건출물에는 필요에 따라 여러 부대시설들이 설비되어져 있으며, 재난 및 비상의 경우 재실자들의 대피를 고려하지 않고 건축물의 효용성, 기능성에 중점을 두고 있다. 화재 및 비상시 재실자들의 대피에 관한 연구중에는 피난시간, 용도변경에 따른 밀집지역, 화재로 인한 대피 지연시간 등을 시뮬레이션의 방법으로 분석하고 예측하려는 프로그램들이 있다. (중략)

As long-span and light-weight deck floor slab are flexible and have low inherent damping, the significant floor vibration could be induced by residents' activities. These floor vibrations affect to safety and serviceability of building structures. So the vibration criteria are applied to the quality assessment of building structure. Therefore, the accurate vibration analysis should be performed for the correct assessment of deck floor slab. In this paper, practical analysis method with considering orthotropic rigidity of deck floor is proposed tot the accurate vibration analysis of dock floor slabs with form deck plates.

This paper simulated the virtual constructions design that helps make constructions design effectively done by assembling materials as components and patterns using studs in steel house method. We also propose the virtual constructions design technology which makes change of constructing easy and reduces the cost effectively through a simulation of construction design like design, analysis, change information, and assembly in the construction field. It especially is possible for designers and users to change internal and external of a construction easily by using patterns.

With the recent changes in building environments such as low-carbon green growth, there have been increasing demands for the new building system that is eco-friendly and can maximize efficiency such as the unit modular system. For the unit modular system, more than 80% of the whole process is carried out in the factory while in the field, mostly unit module assembling and finish work are done. Thus, the quality at the pre-construction stage when design and manufacturing are done determines the quality of the building as a whole. In the country, the unit modular method was first applied in 2003 to school buildings and has gradually expanded afterwards, but due to the lack of examples and related information as well as the small scale of modular manufacturers, its characteristics have not been sufficiently reflected in design, manufacturing and field constructions. This study, as an attempt to improve the design quality of unit modular buildings, points to the problem in manufacturing and field construction, compares and analyzes its causes, and suggests major points to be considered in the early stage of designing the unit modular buildings.

In recent years, the number of high-rise buildings has been on the rise. As buildings have become larger in scale, significantly different issues related to their construction and maintenance have emerged. In addition, the automation and mechanization of the cleaning work for the curtain wall, one of the most frequently-performed tasks in building maintenance, is required as a fundamental measure. For this reason, a guide-rail cleaning robot system is emerging as one of the measures in response to external factors, including gust. Therefore, this is a preliminary study for the automation and mechanization of the curtain wall cleaning of high-rise buildings, and aims to derive the basic units and prepare for the concept of the guide rail. It is expected to serve as precedent research for the development and operation of a curtain-wall cleaning robot, and to prepare the basis for an final design of optimal guide rail.

A lot of buildings, especially apartment housing, have been dismantled so as to enhance the value of the building without exact assesment for the service life and deterioration degree of the building. Remodeling for an aged building is becoming a hot issue to owners in the public sector and the private sector. Peoples including owner, tenants, constructors recognize the fact that the efficient maintenance of the building during the service life and lengthening the practical service life are very important in point of minimizing LCC. This study suggest a decision making system to judge whether to remodel(renovate) or to reconstruct an aged building. The system is composed of structural performance assesment elapsed(or practical service) life evaluation against whole service life, deterioration assesment of the building equipment, dweller's satisfaction, etc.
