Spectral analysis of multiple cracked beam subjected to moving load

Abstract

In present paper, the spectral approach is proposed for analysis of multiple cracked beam subjected to general moving load that allows us to obtain explicitly dynamic response of the beam in frequency domain. The obtained frequency response is traightforward to calculate time history response by using the FFT algorithm and provides a novel tool to investigate effect of position and depth of multiple cracks on the dynamic response. The analysis is important to develop the spectral method for identification of multiple cracked beam by using its response to moving load. The theoretical development is illustrated and validated by numerical case study.

Nonlinear Dynamic Analysis of Cracked Beam on Elastic Foundation Subjected to Moving Mass

“…D. Froio1, R. Moioli1, E. Rizzi [7] and D. T. Pham, P. H. Hoang and T. P. Nguyen [8] used the nonlinear elastic foundation and New NonUniform Dynamic Foundation applied to analyzed response of beam subjected to moving load and the results show that the influence of velocity has effects significantly on dynamic response of structures. N. T. Khiem, P. T. Hang [9] used a spectral method applied to analyzed response of a multiple Cracked Beam subjected to moving load. Using analytical and finite element methods, Murat.…”
