External wall cleaning is a task that is currently being performed by human workers. The recent surge in the number of high-rise buildings has led to such problems as difficulties in cleaning the wall, high risk to the specialized workers, and increased maintenance expenses. As a fundamental measure to perform external wall cleaning work in a safer manner, automation/mechanization has been on the rise. This research aims to classify façade types and analyze the performance requirements of a wall-cleaning robot, as preliminary research to develop a wall-cleaning robot. The replacement of specialized workers with robots is expected to improve both safety for workers and quality of cleaning.

1980년대 이후 건축기술의 발달과 함께 50층을 넘어 100층 이상의 초고층 건물 시대로 진행되었다. 초고층건물의 등장으로 이에 따른 기초두께의 증가가 불가피하게 되었다. 이 때 기초 두께를 감소시킴으로 인해 공기 및 경제성이 향상 될 수 있다.

Recently GPS has been playing an increasingly important role in geodesy and positioning, for example, car navigation system, surveying, ITS(intelligent transport systems), LBS(Location Based Service) and so on. For telematics application, reception conditions of GPS signal are important. In some situation, such as in areas between buildings, metropolitan areas or areas with large skyscraper complexes, there are situations whereby the satellite signal is seriously restricted by various obstacles. Before the signal arrives at the receiver, it may be blocked, reflected, delayed, attenuated or scattered by terrestrial obstacles such as buildings. In this paper, we present satellite imagery data for telematics application. Therefore, for propriety of this studies, we made a GPS satellite visibility experiments in Bun-Dang on same time. This paper describes an approach to calculate building level using 0.6m, 1m, 6.6m resampling aerial polo imagery in stead of the satellite imagery and make a comparative study of accuracy. This paper tests the simulation of GPS signal using the building level.

We studied the example of various side on effect the aging of exterior materials for concrete structure by analyzing the reason of water leakage in exist serviced skyscraper apartment. For this side, we would like to suggest the proper waterproofing materials and construction methods resulted in the mechanical performance test. So, it could be ensured the leakage safety for using residence facility and crowd utilization after repairing. It may maximize the durability for the concrete structure.

As the skyscraper matures as a building type, its role in actively connecting to, and reinforcing, major threads of urban fabric becomes increasingly more important. The creation of public spaces inside of and adjacent to tall buildings allows for significant additions to the public realm, facilitating better connections between varied uses, providing needed access to critical transportation functions. In this more integrated version of the tall building type, the density afforded by a vertical structure is complemented by strategically devised porosity of plan and section. This paper examines three major tower projects which exemplify a progressive approach to permeable design: the recently completed Jingan Kerry Centre in Shanghai, the Lotte Supertower in Seoul, now half completed, and the One Vanderbilt tower being proposed next to Grand Central Terminal in New York City. These projects suggest possibilities for innovative approaches to private development strategies, public planning processes, and architectural design.

In Part One, I documented the evolution of the use of the elevator and the iron frame to build ever-taller buildings that would eventually be called "skyscrapers," to offset the ever-increasing cost of Manhattan real estate. By the start of the Great Depression of the 1870s in 1873, New York architects had erected two ten-storied skyscrapers. In Part Two I document the major events, designers, and buildings in New York, Chicago, and other American cities that eventually culminated in the ability to erect 20 story skyscrapers by 1890.

The evolution in the use of the elevator and the iron frame to build ever-taller buildings that would eventually be called "skyscrapers" is still somewhat shrouded in the mist of history. This two-part paper is an attempt to document the significant persons and events in that evolution, showing that these had a greater continuity than that previously recorded. In this first part, I discuss how the exploitation of the elevator in the design of buildings allowed "skyscrapers" to be built taller than the five-six story limit imposed by stairways, so that their owners could include more and more rental square footage needed to offset the increasing cost of Manhattan real estate. The use of iron framing for the interior framing in these taller buildings would reduce the amount of square footage lost to construction, thereby also increasing the rental return from the building. By the start of the Great Depression of the 1870s in 1873, New York architects had erected two ten-storied skyscrapers.

According to the conversion of building into skyscraper, most buildings have curtain wall structures, so the shading device of building is required. The types of shading systems are a roller shade, venetian bind, and vatical blind and so on. A miler shade is mostly used among the shading systems. An experimental evaluation was verified whether there was an effect of shading materials(Perforated panel, Fabric) in each condition by an experiment with artificial lighting and daylight.

Construction projects are being the skyscraper and the large size by limited site condition and developing construction technology. Therefore, Steel structure work is steadily increasing caused by easy to work and structural safety. However, steel-frame work has the large incidence of heavy accident potentially. Recently a research group has recently developed newly designed self-supported steel joint for enhancing safety of steel erection work. Before applying the steel joint in a construction site, economic evaluation should be performed. Thus, we proposed the method for measuring economic efficiency of the new steel joint and verified economic feasibility of the steel joint method through a case study. As a result, Steel erection method using by self-supported steel joint showed economic rather than the one using by H-beams.

In the modern city in which the high-density and complex land use is needed, high-rise residential-commercial buildings appeared as a scheme to arrange a metropolitan residence with multiple high-techs and to induce activation of the city with leading the settled population to flow into the city. And the need of the times is to actively apply the eco-friendly notion to the architecture. In this study, the works of Ken Yeang who is regarded as an eco-friendly architect to make high-rise residential-commercial buildings ecological should be focused on with analyses of eco-friendly characteristics in inside, intersection between inside and outside, and outside of his works. The result o the study would be the suggestion to design eco-friendly high-rise buildings which make the city rise in quality.
