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.

현행 지적도에는 건물 위치가 표시되지 않아 지적도 활용 시 건물 위치 식별이 어렵고, 지적현황측량에 따른 비용과 시간의 소요와 불편을 격고 있으며, 지상 건물의 경계 침범으로 인한 분쟁과 소송이 일어나고 있다. 건축물 경계 추출에 관한 선행연구에서 수치정사사진과 LiDAR를 이용한 건물 경계를 추출은 원칙적으로 지적측량의 원리와 상이한 기준으로 실제 지상의 외벽 경계선이 아닌 건축물의 옥상층 경계선을 추출하였다. 따라서 본 연구에서는 건물등록을 위해 시도해 보지 않았던 건축도면을 이용하여, 기존연구에서 고려되지 못한 지붕선이나 처마선이 아닌 실제 지적측량에서 기준이 되는 외벽의 경계선을 등록하기 위해 건축도면을 활용하였으며, 등록하는 과정에서 ArcGIS 엔진을 이용하여 개발한 자동 등록 방법을 사용하였다. 지적도 필지 경계선과 건축도면의 필지 경계선을 기준으로 등록한 결과 지적현황측량 성과와 수치지역에서 연결오차로 RMSE가 0.10m, 도해지역에서 0.16m로 나타났다. 따라서 건축도면을 이용하여 지적도에 건축물의 경계를 등록함으로써 지상측량을 보완할 수 있으며, 3차원 지적구축을 위한 기반을 조성하고, 지적재조사사업에서 시간과 경비를 획기적으로 절감할 수 있을 것이다.

20세기 건축의 선구자 중 한 명으로 손꼽히는 건축가 미스 반 데어 로에(Mies Van der Rohe). 요즘 주위에서 많이 볼 수 있는 유리로 만든 외벽을 처음 활용해 투명성과 반사 효과를 제시한 그의 건축 세계를 살펴본다.

Generally, the envelope of a freeform building is composed of a structure made with rectangular or C-shaped steel pipe, and steel or aluminum panel finishes on the structure. However, these construction methods increase material loss and cost and time. There are also numerous cases of misunderstanding of design and difficulties in construction, which frequently cause construction errors. Such construction errors decrease construction productivity, resulting in poor construction quality and the need for rework, as well as cost and time overruns. To solve the problem, this study proposes a 3D coordinate control technology for freeform structure implemented through a CNC(Computerized Numerical Control) Twisted tube method, and by extension, develops a BIM-based envelope construction method for freeform building.

Exterior wall molding, which is widely applied as a design element of the exterior wall of domestic apartment, should be applied as a nonflammable or semi-nonflammable material grade according to the rules on standards for evacuation/fire protection structures of buildings. For this reason, stone and AL sheet are mainly used, but stone is expensive and design autonomy is low. Inorganic reinforced CLC nonflammable molding was applied to the exterior wall of the building through tests of nonflammable performance, noise reduction, and installation stability.

In this paper, we have performed a numerical calculation of the scattered electromagnetic field around the building to evaluate electromagnetic interference caused by the building in the TV frequency band. The relations between the exposed concrete area of a building wall and the magnitude of the reflected wave have been examined in the case that the electroagnetic wave absorbers partially cover the building wall. From the obtained scattered electromagnetic field, we have calculated the DU radio and the required reflection loss of the electromagnetic wave absorbers which attached on the building wall to protect TV ghost.

This study is to diagnose causes of damage and defects on external walls of brick structures, focused on "Naju Noahn" Catholic Church of Modern Architectural Properties. The causes of crack and deflection are overloading, shortage strength of arch. Among those, main cause is cauesd by shortage strength of arch because center of arch is dislocated and skew back of arch is small angle. The causes of damage and elimination are weathering, plants of friction, freezing and thawing, durability decrement of material and attach defection. This defects and damage is caused by high-moisture that occurs in soil. The causes of discoloration are change of soil moisture and flimsy brickwork. These defects and damage are mainly occurred in coping of cornice, weathering of window sill.
