Abstract: Modal properties of light roofs such as cable roofs backed by cavities with openings are theoretically investigated. Taken into account are the interaction between the roof and the air enclosed by the cavity, the air outside ...

Abstract: This paper examines the response of hemispherical, air‐supported structures to turbulent wind, both theoretically and experimentally. Wind‐tunnel tests were conducted on an aeroelastic model of a hemispherical, air‐supported ...

Abstract: This paper complements the theoretical study of the same subject. The aim is to verify the theory formulated in the companion paper. Free vibration of large‐span, self‐supported, lightweight roofs backed by cavities with ...

Abstract: Wave forces on fixed offshore structures due to short‐crested seas are investigated using the directional spectra and an alternative model accounting for spatial correlation of water particle motions in terms of coherence ...

Abstract: A plane strain transmitting boundary for axisymmetrical dilation problems is presented. Such a boundary can facilitate both analytical and finite element investigations of dynamic interaction of an embedded footing or a ...

Abstract: Stiffness constants and constants of equivalent viscous damping are presented for single, vertical piles in the form of tables and charts. The soil shear modulus is either constant or varies with depth according to a ...

Abstract: Dynamic experiments with a large group of closely spaced, small piles were conducted in the field in order to verify the different theories available and to examine the applicability of some simplified approaches such as ...
