Environmental Requirements

In the recent years, people begin to concern more about the development of new energy source, because of the global economic development and more stringent environmental requirements. The wind power is rapidly developed for its low price and it’s friendly to environment and the wind energy and building integration also becomes a very important mode to develop new energy sources. The wind driven generator and high-rise building structure were integrated, and ANSYS was used to complete the static analysis of the equivalent dead load action of high-rise building with wind driven generator under six different wind pressure. By comparing the results of the calculations, the feasibility of the wind energy and building integration was initially verified.

Aerodynamic Interference

The paper summarizes the results of wind tunnel tests of the influence of aerodynamic interference on wind action of a high-rise building design in Warsaw. Measurements were accomplished in Wind Engineering Laboratory of Cracow University of Technology. Wind pressures on external surfaces of the building model were acquired in two different situations. Firstly, only the building model was placed in the tunnel working section, secondly, the building model with the nearest surroundings was taken under consideration. A study of the character of wind action differences caused by the nearest surroundings of the building was the main aim of the paper. Wind pressure coefficients on the external building surfaces and the difference of horizontal wind action on full scale were compared.

The Mean

High-rise buildings are very sensitive to wind excitations, and wind-induced responses have always been the key factors for structural design. Facade openings have often been used as aerodynamic measures for wind-resistant design of high-rise buildings to meet the requirement of structural safety and comfort. Obvious wind speed amplifications can also be observed inside the openings. Therefore, implementing wind turbines in the openings is of great importance for the utilization of abundant wind energy resources in high-rise buildings and the development of green buildings. Based on numerical simulation and wind tunnel testing, the wind loads and wind speed amplifications on high-rise buildings with openings are investigated in detail. The three-dimensional numerical simulation for wind effects on high-rise building with openings was firstly carried out on FLUENT 15.0 platform by SST k − ε model. The mean wind pressure coefficients and the wind flow characteristics were obtained. The wind speed amplifications at the opening were analyzed, and the distribution law of wind speed in the openings is presented. Meanwhile, a series of wind tunnel tests were conducted to assess the mean and fluctuating wind pressure coefficients in high-rise building models with various opening rates. The variation of wind pressure distribution at typical measuring layers with wind direction was analyzed. Finally, the wind speed amplifications in the openings were studied and verified by the numerical simulation results.

In this paper, the contents, meaning and importance of conceptual design in the high-rise building structure design are explored from the following respects: structural system, facade layout and multi-channel seismic line. It not only provides a strong protection of concept for calculation of high-rise building structures, but also accumulates some experience for the research on conceptual design of high-rise structures.

Element Program

The dynamic property of a high-rise building structure and time-history analysis under earthquake were analyzed by using the finite element program ANSYS. A modal analysis of the tower was conducted and the first 20 frequencies and modal shapes were obtained. The displacements and inner force under the earthquake were calculated. The result showed that the structural stiffness was enough to sustain earthquake load; and the stiffness distributed equally. These results can provide reliable basis for structural design.
