Baku, the capital of Azerbaijan, has seen a boom in construction in recent years. The old Baku city has been rapidly transforming into a new hub of high-rise buildings and lively cultural centers hosting the Euro Vision Song Contest in 2012 and European Games in 2015. A major population shift to Baku from its suburbs and the countryside has resulted in the doubling of Baku's population in the 4 years between 2009 and 2013. As of January 2013, Baku's population reached four million people, 43% of the citizens in Azerbaijan according to The State Statistical Committee of Azerbaijan. With this trend, the city needs more high-rise buildings to accommodate rapidly increasing demands for more housing and business space. Until the Azerbaijan Seismic Building Code was published in 2010 and became effective, many different seismic criteria, in terms of building codes and seismic intensities, were used for all new high-rise projects in Baku. Some designers used the SNIP (Russian) code with seismic level 9 or level 8 with 1 point penalty. Others used the Turkish code with Seismic Zone 1, UBC 97 with Zone 2 through 4, or IBC with Sa = 0.75 g through 1.0 g. The seismic intensity is now clarified with the Azerbaijan Seismic Building Code. However, the Azerbaijan Seismic Building Code is appropriate for low-rise buildings applications but may be inappropriate for high-rise project applications. This is because the code-defined response spectrum yields unrealistically conservative seismic forces for high-rise buildings with long periods, as compared to those determined by other internationally accepted building codes. This paper provides observations and recommendations for code-based seismic load assessment of high-rise buildings in the Baku area.

This paper describes the structural solution for the design of a 29-story high-rise tower, which features a large office space above the Kabukiza Theatre. Kabuki is a type of Japanese traditional drama, and Kabukiza is the home building of Kabuki. GINZA KABUKIZA is the fifth generation of the Kabukiza Theatre, the first of which was built in 1889. In order to support 23 stories of office space above the theater - featuring a large void in plan - two 13-meter-deep mega-trusses, spanning 38.4 meters, are installed at the fifth floor of the building. Steelwork is used as a primary material for the structure above-ground, and a hybrid response control system using a buckling-restrained brace and oil damper is adopted in order to achieve a high seismic performance. This paper also describes the erection process of installing hydraulic jacks directly above the mega-truss at column bases, in order to keep the structure above the truss level during construction. The temple architecture of the previous Kabukiza is carefully restored by incorporating contemporary light-weight materials supported by steelwork.

This paper discusses the economics of skyscraper construction in Manhattan since 1990. First the paper reviews the economic theory of skyscraper height. Next it documents the frequency and heights of skyscraper construction in the last 25 years. Then the paper reviews the relative movements of office rents, condominium prices, and construction costs. Statistical results suggest that the resurgence of Manhattan's skyscraper construction is being driving by the rise in the average price of apartments, and is not being driven by rising office rents or falling construction costs. Statistical evidence shows that the height premium has not been rising over the last decade. Developers have been purchasing air rights (and bidding up the prices) in order to satisfy the demand for supertall buildings. In the next five to ten years, Manhattan is likely to see over thirty 200-meter or taller buildings, as compared to only four since 2010.

Housing consumers prefer high-rise mixed-use apartments because of one-stop living style, and high quality of life. This study investigated the residents community with the residents who lived in the apartments and the future residents who will live in the apartments to investigate the usage of the public spaces and the influence of the space to form housing culture of residents family community. All data were taken from the response of two hundred forty three questionnaire to be gathered during 20th of June through 24th of August in 2003. Data were analyzed with percentages, means, t-test, and variance analysis using SPSS/PC+. Residents in four high-rise mixed-use apartments feels that the public space in the apartments were mainly provided by their convenience of the construction companies not for the residents. Physical conditions of public space in high-rise mixed-use apartments should be environmentally friendly housing space in which nature and human can be coexisted. It also should be high-tech system housing with which SOHO can be operated. And different custom-made spaces which the residents' needs can be satisfying should be provided. The public space should be recommended to be multi-purposed room because the space will be differentiated with the circumstances of the area, the residents' age differences, and the variety of the family's life style. Moreover, the various programs should be supplied to run the public space efficiently.

The purpose of this study is to investigate the concentration of sea-salt distribution giving great characteristic environmentally. Therefore the field measurement was conducted to target high-rise apartments constructing in reclaimed land of Busan and measured the concentration of sea-salt by means of distance and height of high-rise apartments from coast. The results of this study were as follows ; 1) The more a horizontal distance is far from coast, the more concentration sea-salt become low. But this study can not draw conclusion exactly as differ from a tendency of the thing close to the coast and the land. 2) In the near seaside, No.132 apartment accords existing research result that in difference of the concentration of sea-salt by height, the more height is high, the more that is high. But in seaside, No.117 apartment of middle point appears that the upper story and the lower story than middle story. Once more, in inland, No.132 apartment and No.117 apartment tend toward opposite it of the seaside. The reason that the result of this measurement and existing study is not agreement is thought that it occurs to turbulent flow between apartments by construction of high-rise apartments group.

With the increasing number of high-rise and large-scale buildings, modern buildings are becoming intelligent, and are incurring high construction costs and requiring careful maintenance. Maintenance works for high-rise buildings significantly depend on human labor, unlike other construction processes that are gradually being automated. The resulting accidents may produce very high social and economic losses. To address this problem, herein, this paper proposes robotic building maintenance system using multi-robot concept, in specific, cleaning a building facade which is directly subjected to minimize human labor; that improves the process efficiency and economic feasibility. The sensor for detecting contamination of building's outer-wall glass is proposed; Kalman filter was used for estimating robots' status with the contamination of the window glass. Task allocation of the sensor based multi-robots for an effective way of task execution is introduced and the feasibility was verified through the simulations.
