Most international codes and standards provide guidelines and procedures for assessing the along-wind nominal value of equivalent static wind loads on tall buildings. Despite their analogous multiple-parameters expression, notable scatter exists among the parameters and so among the nominal values of wind loads and wind effects predicted by the various codes and standards. Based on the comparative study of parameters, the GB50009 (China), ASCE7 (American), and AIJ (Japan) were selected as the representative codes in the Asia-Pacific region, and the calculation principles and methods of the nominal value of equivalent wind loads in the along-wind direction were reviewed. Parameters such as the basic wind velocity, wind profile, turbulence intensity, gust effect factor and also the inter-influence among them were considered. The gust effect factor and the influence on it were also expounded. A detail example including three representative buildings was presented to illustrate the overall comparison and the main findings were also highlighted in the example and the relevant discussion. The results show that the along-wind nominal value of equivalent static wind loads is the largest in AIJ and more or less the same in GB50009 and ASCE7.
