“…4f) is half-elliptic. This half-elliptic envelope is very similar to that reported in (Tamura et al, 2014), which in part suggests validation of the measured data. Unlike the symmetric trajectory for the single building, however, those for the LB cases shown in Fig.…”

“…The intra-building aerodynamic correlation, i.e., the correlation between wind force components on each building, is related to the combination of resultant directional wind-induced responses (Chen and Huang, 2009;Tamura et al, 2014). As mentioned in the introduction, the correlation may differ significantly from that for a single building.…”

“…In addition to modification of wind force magnitude on an LB, therefore, the correlation between wind force components within each building likely differs from that for an isolated building. This correlation, which is related to the combination of the resulting directional structural response (Thoroddsen et al, 1988;Tamura et al, 2001;Tamura et al, 2008;Tamura et al, 2014), is termed the intra-building aerodynamic correlation in this work. Furthermore, the existence of the structural link can couple the vibrations of the two connected buildings by transferring internal forces.…”

This paper investigates the intra-building and inter-building aerodynamic correlations of linked buildings (LBs, i.e., adjacent tall buildings structurally connected by links such as skybridges, skypools and skygardens). Spatiotemporal wind pressure data on a few typical LBs with different gap distances are used to examine the two aerodynamic correlations. The intra-building aerodynamic correlation is examined using correlation coefficients and trajectories between wind force components on the building. Results show that the intrabuilding aerodynamic correlations for the LBs differ considerably from that for the isolated building, especially in the correlation between along-wind and torsional force components. The inter-building aerodynamic correlation is then presented in terms of the correlation coefficients between local wind force components and between generalized force components of the two buildings. The along-wind inter-building correlation is found to decrease with increasing gap distance, whereas the variation of cross-wind inter-building correlation is more complicated. In addition, it is illustrated that the wind-induced response of the LB is related positively to the correlation coefficient between the generalized force components of the two buildings in the associated unlinked case.

“…A number of studies concerning the linear combinations of alongwind, crosswind and even torsional wind load effects have been reported in the literature (Melbourne, 1975;Vickery and Basu, 1984;Solari and Pagnini, 1999;Tamura et al, 2000Tamura et al, , 2001Tamura et al, , 2008Bartoli et al, 2011;Tamura et al, 2014). Tamura et al (2000Tamura et al ( , 2001Tamura et al ( , 2008 carried out comprehensive investigations on the combinations of the maximum value of one of the wind force components with two other simultaneously recorded force components for low-and middle-rise buildings using pressure measurement data.…”

Summary Ping An Finance Center with a height of 600 m and 118 storeys, located in Shenzhen, is currently the second tallest building in China. This paper presents a comprehensive study of wind effects on the supertall building through wind tunnel testing and field measurement. The wind‐induced loads and pressures on the skyscraper were measured by high‐frequency force balance technique and synchronous multipressure sensing system, respectively. In the wind tunnel study, a whole range of characteristic properties, including mean and r.m.s force coefficients, power spectral densities, coherences, correlations, and phase‐plane trajectories, wind‐induced displacement, and acceleration responses were presented and discussed. In addition, a field measurement study of the dynamic responses of Ping An Finance Center was conducted during a tropical cyclone, which aimed to verify the design assumptions and further the understanding of the dynamic properties and performance of the 600‐m‐high supertall building, including natural frequencies, damping ratios, and wind‐induced structural responses. Then, the serviceability of the skyscraper is assessed on the basis of the experimental results and field measurements. The outcomes of this combined model test and field measurement study are expected to be useful for the wind‐resistant design of future supertall buildings.
