摘要
大型体育场主看台挑篷是典型的风敏感结构,挑篷上的风荷载和由此诱发的挑篷的风致振动常常是控制结构安全性的主要因素.本文系统回顾了国内外在体育场主看台挑篷抗风研究领域的进展,主要涉及刚性模型测压试验研究、气弹模型试验研究、现场实测、风振响应计算和现有规范等方面,并对进一步的研究方向提出建议.
<Abstrcat> The grandstand cantilevered roofs of large stadiums are typical wind-sensitive structures. The wind loads on the cantilevered roofs and the wind-induced vibration are usually the major factors which control the security of structures. The development of wind resistance studies on stadium grandstand cantilevered roofs, both nationally and internationally, is systematically reviewed in the paper, which mainly includes wind pressure measurement on a rigid model, aeroelastic model wind tunnel test, actual measurement, computation of wind-induced vibration and current code. The suggestion on further studies is given at last.
