Abstract:
The reason of abnormality appeared during the displacement measurement in the frame static test is analyzed. Some improvement approachs are put forward，including more smoother contact surface, bigger measuring block and so on. Based on the analysis of the stiffness of the whole frame, the derivation method for calculation the displacement of an abnormal measuring point by using the normal measuring points is proposed. The method is validated by additional two tests which do not contain abnormal displacement measuring points. The results show that the error of the computative method is less than 5％.
