Abstract: The wave forces computed at the displaced position of offshore structures may introduce additional drift forces. This contribution is particularly significant for compliant offshore structures that ...

Abstract: The nonlinearity in the wind loading expression for a complaint offshore structure, e.g., a tension leg platform (TLP), results in response statistics that deviate from the Gaussian distribution. ...

Abstract: A statistical analysis of the moment capacity of a tubular reinforced‐concrete (R/C) section is performed. The moment capacity of the cross section is estimated utilizing a second‐order stress‐strain relationship for ...

Abstract: In this paper, a new method is proposed for the expansion of nonlinear drag forces in terms of multivariate Hermite polynomials correct up to the second order. The drag‐force formulation includes the effect of instantaneous ...

Abstract: Two independently emerging time-frequency transformations in Civil Engineering, namely, the wavelet transform and empirical mode decomposition with Hilbert transform

Abstract: Recently, there has been growing utilization of time-frequency transformations for the analysis and interpretation of nonlinear and nonstationary signals in a broad spectrum of science and engineering applications. The ...

Abstract: Time-frequency transformations have gained increasing attention for the characterization of nonstationary signals in a broad spectrum of science and engineering applications. This study evaluates the performance of two ...

Abstract: The Civil Engineering community has long needed methods of accurate global displacement measurement for use in construction and more recently in the areas of structural health monitoring. Global Positioning Systems (GPS) ...

Abstract: In order to detect intermittent first- and higher-order correlation between a pair of signals in both time and frequency, a wavelet-based coherence and bicoherence technique was developed. Due to the limited averaging in ...

Abstract: Turbulence-induced changes in aerodynamic force characteristics on an oscillating rectangular prism were investigated in this study. It encompassed examination of aeroelastic quantities, i.e., flutter derivatives, and the ...
