Appendix 5.5.d Characterization of Wind Loading of Telescopes
Ground-based telescopes operate in a turbulent atmosphere that affects the optical path across the aperture by changing both the mirror positions (wind induced vibrations) and the air refraction index. Although the characteristics of the atmosphere are well understood in the inertial range, the validity of the homogeneous, isotropic field assumption is questionable inside the enclosure and in t...
متن کاملParallels between wind and crowd loading of bridges.
Parallels between the dynamic response of flexible bridges under the action of wind and under the forces induced by crowds allow each field to inform the other. Wind-induced behaviour has been traditionally classified into categories such as flutter, galloping, vortex-induced vibration and buffeting. However, computational advances such as the vortex particle method have led to a more general p...
متن کاملSensitivity of Overpass Bridges to Wind and Traffic Loading
bridges are planned for construction on the U.S. 59 in Houston, Texas. Each bridge will be of the tied-arch type and will be constructed on-grade over cut areas with clear spans of 228 f t (69.5m). To expedite construction, unique procedures are planned which use existing bridges as platforms for final fabrication of the tied arches. This procedure requires consideration of wind loadings on the...
