用测力天平技术研究超高层建筑的动态风载

Study on Aerodynamic Loads of Super High-rise Buildings by High Frequency Force Balance Technique

通过风洞实验研究了不同外形的超高层建筑的动态风载．实验采用多种不同外形的刚性模型，通过高频测力天平技术研究了建筑物长细比、截面形状、截面长宽比及湍流强度和风向的影响，获得了一些新的结果．

Thirteen models have been tested using high frequency force balance (HFFB) technique in a wind tunnel to investigate the effects of cross-section configuration, aspect ratio, turbulence intensity, etc. on the aerodynamic loads on super-tall buildings. Some new results which are presented in this paper may be used as reference in next revision of the relevant codes.
