A series of wind tunnel tests were conducted on 7 super-tall buildings with various polygon cross-sections, including triangle, square, pentagon, hexagon, octagon, dodecagon, and circular. The primary purpose of the present study is to investigate the effect of increasing number of sides on aerodynamic characteristics for super-tall buildings. Wind tunnel tests were conducted under the turbulent boundary layers whose power-law exponent is 0.27. Fluctuating wind pressures from more than 200 pressure taps were recorded simultaneously, and time series of overturning moments were calculated considering tributary area of each pressure tap. The results show that the overturning moment coefficients and the spectral values decrease with increasing number of sides, and the largest mean and fluctuating overturning moments were found for the triangular super-tall building, and the largest spectral values were found for the square super-tall building. The analysis should be conducted more in detail, but currently it can be roughly said that there seems to be a little differences in the aerodynamic characteristics for the super-tall buildings whose number of sides is larger than 5 or 6.

In this paper, a mass damper was proposed and the plan on its practical application for wind-induced vibration control of a super-tall building was introduced. The damper was developed to generate forces which were calculated by both linear and nonlinear control algorithms. A controller in which the control algorithms were embedded was developed and it was verified through experiments that the damper with the controller could show dynamic behavior as a designer had intended. A preliminary design of a super-tall building with the damper was conducted. As a nonlinear algorithm, decentralized control algorithm which only requires to measure damper-installed floor response in order to calculate the control force was proposed. Simulation results indicated that the proposed damper could provide better or at least equivalent control performance than the usual active/hybrid type damper controlled just by existing linear control algorithms.

This study fouces on the electricity generation of B1PV system in the super-tall buildings. To improve the efficiency of the B1PV system, solar irradiance and air temperature should be taken into consideration. This study does research on, one of two main parameters, the solar irracliance in the super high-rise buildings. According to the measurement of solar irracliance, it increased with altitude. It is, particularly, more obviously in the super-tall buildings than others. Subsequently, to make an accurate B1PV elecrticity generation prediction，it is necessary to anaiyze the solar irracliance distribution on the super-taII building's facade which is a prerequisite for optimal B1PV system design.

The study was conducted for the purpose of determining the size of the floor area of super-tall building by use. So, considering the urban capacity in the region around the super-tall buildings, it has been developed for the prediction methodology of the size. Through the information of the buildings and the cadastral, the correlation and regression analysis were performed by 18 super-tall buildings located in Korea As a result, the residential floor capacity was under the influence of land use of residential and green space, and the business floor capacity was under the influence of land use of green space. Hotel and commercial area, where as the land use and has shown significant results that do not. of a building the size of the surrounding areas for residential and green space and commercial floor area size of the impact of land use for was larger. Hotel and commercial floor capacity, where as the land use and has shown significant results that do not. After this study, it is need to the consideration of the urban capacity around region and supertall buildings to enhance the role of public of supertall buildings. And it will be need to improve the accuracy of prediction with applications to the information of buildings around the region of supertall buildings.
