With the increase of the span and unit area of air-supported membrane structure coal shed,the changes in the internal pressure distribution characteristics become complex.Currently,there is a lack of field verification on the relationship between the internal pressure fluctuations and displacement response changes in large-scale projects,in order to determine whether the theoretical calculation values of structural displacement response are consistent with the measured data.Based on the health monitoring system of the air-supported membrane structure coal shed with the size of 115m×317m located at Yueqing Power Plant,Zhejiang Province,the lifting-pressure maintaining test on the structure before the typhoon was carried out.The displacement responses of seven different measuring points of the structure were measured,and the displacement response characteristics of the structure under the adjustment of internal pressure were analyzed.At the same time,the measured results were compared with the numerical simulation results to verify the reliability of the pressure equivalent analysis method for large-span air-supported membrane structure.
