( Civil Engineering of Xian University of Technology and Architecture, Xian 710055, China)Abstract: The recorded ground motion was decomposed into a finite number of time series with energy in nonoverlapping frequency bands by discrete wavelet analysis method to explore the displacement response laws of span structures under ground motion. In this process, wave passage effect included in uniform excitation and multi-support excitation was considered. The displacement laws were obtained to multi-support excitation, and the levels for traveling wave excitation and uniform excitation were also calculated respectively, so that the comparison of the displacement response laws in the building to two types of excitations can be made.
Keywords: wavelet; wave passage effect; multi-support excitation; uniform excitation
