Seismic studies on the Derbyshire dome
The Derbyshire Dome is thought to have been a stable uplifted area since at least Lower Carboniferous times. This project is principally concerned with four 30km seismic refraction lines which crossed the limestone outcrop of Derbyshire and N. Staffordshire in order to investigate the Dome's upper …

Wind effects on a hemispherical dome
… of pressures over the surface of a hemispherical dome is made, and the flow parameters of these experiments are compared. A hemispherical dome is subjected to a flow in the open-throat wind tunnel at VPI&SU, and the resulting pressure measurements are given. An experiment utilizing the 6-ft square …

Triax dome modeling with I-DEAS 4.1
… in today's society, glued-laminated Triax domes are being designed and built. Even though many have already been constructed, no methods have been established to accurately determine the ultimate load capacity or the factor of safety. Several ABAQUS finite element analyses have been …

Parallel lamella dome under wind and snow loads
… and to study the sensitivity of parallel lamella dome under wind and snow loads. The modified Riks/Wempner method is used to perform the prebuckling and postbuckling analysis. The European Convention for Constructional Steelwork (ECCS code) is used as the code of practice for design wind pressures …

Geometrically nonlinear finite element analysis of a lattice dome
… the finite element method modelling of a lattice dome is presented. Linear analyses and geometrically nonlinear analyses of the dome are performed. In addition, a buckling load prediction method is studied and extended to the multiple load distributions. The results obtained from linear analyses …

Adapting the OpenRelativity toolkit to multi-perspective dome projection
… thesis investigates the combination of a full-dome planetarium experience with the intuitive explanations and visuals of the OpenRelativity game engine. From its inception, OpenRelativity was meant as a toolkit to produce many learning experiences, and this thesis represents the latest attempt …

A comparative study of structural material for dome construction
… Space structures, and more specifically, the dome structural system is an efficient way to achieve this desired goal. The benefit of domes is that it can be shaped in such a way so that the members are only under axial stresses. Typical construction materials for large span braced domes are …
