中文摘要:
      为解决强震作用后倾斜高层建筑结构监测存在的精度低、用时长等问题,提出高精度强震作用后倾斜高层建筑结构形变监测方法。通过确定回归平面强震后倾斜高层建筑结构的法线倾斜值、倾斜角与倾斜方向,来确定强震作用后倾斜高层建筑结构形变情况,完成强震作用后倾斜高层建筑结构的形变监测。使用BXJC 1.0软件进行建筑高层建筑形变模拟实验,在建筑高层附近设定四个基准点,基于建筑高层的底部每个立柱中近似等高方位设定16个形变监测结构点,实验发现:所提方法监测误差小精度高,监测误差最大值为0.05%,且监测用时较短,证明此方法进行监测的可行性。
英文摘要:
      A high-precision monitoring method of structural deformation of inclined high-rise buildings after strong earthquake is proposed to solve the problems of real-time monitoring of inclined high-rise buildings after strong earthquakes; such problems include low precision and long time consumption. The structural deformation of the building under a strong earthquake is determined by defining the normal inclination value, inclination angle, and tilt direction of the inclined high-rise building after a strong earthquake in a regression plane. Then, deformation monitoring of the inclined high-rise building after a strong earthquake is completed. The deformation simulation experiment of the building is conducted by using BXJC 1.0 software. Four reference points are set near the building, and 16 deformation monitoring points are set on each column at the bottom of the building. The proposed method has the advantages of small error (the maximum monitoring error is 0.05%), high precision, and short monitoring time. Thus, the method can be used for real-time monitoring.
