摘要 在目前已有的课题研究成果基础上,本文以监测我国新型高层建筑质量为主要重点研究的背景,测量识别我国高层建筑主体结构的风道运动影响时程和相互响应的计算结果,模拟了我国高层建筑与主体风的相互作用及其过程,以及其与高层建筑气动弹性反馈的相互效应,识别得出高层建筑主体结构的空气动力学结构特性以及其对建筑风振动和响应的相互作用及其产生的气动弹性阻尼比,研究了气动弹性阻尼比的运动影响强度随建筑风速的变化规律。同时又以相同的建筑外形、大小以及尺寸的一种刚性气动测力风压测力模型和一种可调节的测力测压模型为例来结合进行实际风洞试验进行研究,通过试验充分考虑气动弹性阻尼对建筑风道的运动影响,验证了这种气动弹性测压模型实际风洞试验研究结果的准确性。
