A Study on the Estimation of the Displacement Responses by the Integration of Acceleration Data of Bridges

It is important to measure e dynamic behaviors of the structures and determine the safety and serviceability of those structures by analyzing the gathered data. It is very much easier and more economical to measure the accelerations than displacements in order to obtain the dynamic responses of a structure, but the physical meanings of the displacements are more clear and definite than those of accelerations. In this study, the algorithm which can evaluate the displacements from the measured acceleration data by integration are developed. The calculated displacements are compared with measured data through the laboratory test and the results represent good agreements. This algorithm is applied to the data of real structures.
