［摘要］對(duì)橢圓形截面和矩形截面的兩棟超高層建筑進(jìn)行了風(fēng)洞試驗(yàn)，獲得了作用在結(jié)構(gòu)上的氣動(dòng)力。在此基礎(chǔ)上計(jì)算得到了用于結(jié)構(gòu)設(shè)計(jì)的順風(fēng)向、橫風(fēng)向的等效靜力風(fēng)荷載及風(fēng)振位移和加速度響應(yīng)。基于《建筑結(jié)構(gòu)荷載規(guī)范》（GB 50009—2012）給出的方法計(jì)算了兩棟高層建筑的等效靜力風(fēng)荷載，與風(fēng)洞試驗(yàn)的結(jié)果進(jìn)行了對(duì)比，并進(jìn)一步討論了振型的階數(shù)對(duì)等效靜力風(fēng)荷載、風(fēng)振位移和加速度響應(yīng)的影響。

Abstract:Two supertall buildings with elliptical and rectangular crosssection respectively were tested in wind tunnel and aerodynamics on buildings were measured. Alongwind and acrosswind equivalent static wind loads（ESWL）, windinduced displacement and acceleration response were calculated to apply to structural design on the basis of results from wind tunnel test. Based on calculation methods in Load code for the design of building structures (GB 50009—2012), ESWL of the two buildings were calculated and compared with the results of wind tunnel test. The impact of vibration mode order on ESWL and windinduced displacement and acceleration response was discussed respectively.

Keywords:wind tunnel test； equivalent static wind load（ESWL）； windinduced response
