在研究高层建筑的抗震问题时,往往引起人们关注的是实测结构的动力特性.但是基于目前的试验方法和条件所限,在这方面的实测资料还较少.为便于测定高层建筑的动力特性,本文将介绍一种简便易行的反冲激振法,并对其实测原理、方法以及框架剪力墙体系的高层建筑动力反应等有关问题加以讨论分析. When studying the earthquake resistance of high-rise buildings, it often attracts people’s attention to the dynamic characteristics of the measured structures. However, due to the limitations of the current test methods and conditions, there are few actual data in this area. To facilitate the determination of the dynamic characteristics of high-rise buildings This paper will introduce a simple and easy recoil excitation method, and discuss and analyze the principles and methods of actual measurement and the dynamic response of high-rise buildings with shear wall system.
