DISCUSSION ON HUMAN COMFORT THRESHOLDS OF STEEL STRUCTURE UNDER WIND LOAD

In the steel structure design，the human comfort issues caused by vibration cannot be ignored． In China， the serviceability checking of steel structure is primarily focused on the structure drift under wind load; the human comfort issues are less focused． China's Code for Design of Steel Structure ( GB 50017—2003) also lacks of provisions for human comfort issues under wind load． According to this situation，this article first summarized domestic and foreign study results on human comfort，and described the factors that affect human comfort，and then introduced some other countries and regions’relevant specifications in the design code of steel structure，discussed some existing problems of the human comfort of building steel structure． Finally，the recommended human comfort thresholds of building steel structure under wind loads were given，which can provide reference for the code revision and for the application of construction．
