Abstract: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.
