Abstract

Pneumatically supported membrane structures belong to wind-sensitive structures, and the on-site measured wind pressure data is a very valuable and intuitive data source for pneumatic membrane structures. However, the acquisition of wind pressure data is difficult, costly, and there is very little research on the processing of wind pressure data for pneumatic membrane structures with long duration. In this paper, all wind pressure measurement points on-site of the pneumatic membrane structure were taken, and based on the characteristics of the measured wind pressure data, the data was preprocessed by dividing the data into abrupt change points to remove baseline shifts caused by abrupt changes. The results show that the algorithm proposed in this paper is efficient, and provides flexibility in dividing abrupt change points, laying a foundation for further extracting useful information from the data. This algorithm can also be applied to data processing with similar characteristics in other applications.
