The paper

which takes the opening roof structure for stadiums as an example

is to conduct a systematic study on the wind load characteristics、vibration modes of the opening roof structure、wind-induced response of opening roof structure、and gust response coefficients.At first

the wind loads in 24 different wind directions were given

which were derived from the wind tunnel tests

and the unfavorable wind direction is selected.Then

the natural vibration characteristic of the structure was studied

and the vibration characteristics were analyzed.After that

on the basis of the analysis of wind loads on the surface of the structure

6 typical wind directions were selected to analyze the wind-induced dynamic responses of structure.Finally

the paper performs a statistical analysis of the wind-induced responses and proposes the suggested values of the wind-induced response and gust response coefficients of structure

which is provided to designers as references for the wind load-resisting of similar opening roofs.
