摘要
介绍作者所在风洞试验室在桥梁结构抗风研究中涉及到的气动措施及其应用方面的内容 .气动措施包括在主梁上增设减小涡振振幅的抑流板 ,提高颤振临界风速的裙板、导流板、降低驰振响应的转向装置 ,改变气动力的主梁开槽方案等 .
This paper introduces the research and appliance of the aerodynamic measures involved in the wind resistance research taken in the wind tunnel laboratory to which the author belongs.These measures include airflow-depressing board for reducing the amplitude of vortex shedding,the apron board and guide plate for increasing the critical wind speed of flutter,the steering apparatus for reducing the response of galloping,and the fluting scheme of the gird for the improvement of the aerodynamic performance.At the mean time,this paper expounds the social and economic benefits brought about by these measures.
