Abstract:As a typical structure vulnerable to a wind disaster,large-scale outdoor billboards collapse frequently under strong wind,which makes a huge potential safety hazard.This paper focuses on the weak link of structural design of large outdoor independent column billboard: damage of billboard panels under extreme wind pressure.The pressure measurement experiment of three wind fields with different turbulence degrees were carried out.Gaussian and non-Gaussian characteristics of panel wind pressure time history are considered,and three different extreme wind pressure calculation methods are use to obtain,the relationship between the extreme wind pressure and the wind field.Additionally,the advantages and disadvantages of the three extreme value calculation methods under different wind fields are compared.This study has a certain reference value for the structural design of billboard panels and the research of the damage probability of the billboard panel.
Keywords:Billboard plates  non Gaussian  fluctuation pressure  extreme wind pressure
