Abstract: A study of the resultants of the inertia and drag-force intensities induced by waves on offshore structures is made. The relationships between these resultants and the corresponding modal forces that govern the structural ...

Abstract: The magnitudes of the effects of the sea-surface fluctuations on the response of wave-excited offshore structures are assessed. Such fluctuations are accounted for by using the linear wave theory in combination with two ...

Abstract: The behavior of unsymmetric buildings excited by incoherent seismic ground motions is studied, and the assessments and information reported make it possible to gain valuable insight into the resulting dynamic response. The ...

Abstract: A practical analytical study is reported that leads to an improved definition of the correlation coefficient for seismic responses of structures. In contrast to definitions currently available, including the widely used ...

Abstract: A practical technique to protect structures against the effects of earthquakes is examined and proposed for use in design. The technique involves the bundling of slender steel members to form columns that are stiff and ...

Abstract: Examinations are made of the dynamic effects associated with modal responses of deep‐water, wave‐excited offshore structures. Such examinations are intended to assess the influences that variations in several parameters ...

Abstract: A recent study suggested that the use of numerical integration methods would generally lead to the erroneous prediction of chaotic behavior for an unforced Duffing’s oscillator. It is shown ...

Abstract: A new analytical expression is proposed for the prediction of the buckle propagation pressure for deepwater offshore pipelines. The expression accounts for the influences of the main factors ...

Abstract: A relatively simple approach is first presented for the approximate analysis of the collapse of circular rings under external pressure. It accounts for geometrical and material nonlinearities, and is able to approximate ...
