In current wind design practice, static wind loads are usually defined to obtain, by simple static analyses, the extreme values of any structural response that would be formally obtained with a strict dynamic buffeting analysis.
India's dynamic economy, buffeted by the broader global slowdown and uncertainty about Europe, is wobbling precariously: the rupee has weakened badly, economic growth is slowing and private investors are spooked by governmental inaction or timidity on a long list of reforms on economic issues including pensions, land acquisition and foreign investment in retail.
Mr Pei describes a "buffet" dynamic among bureaucrats, whereby "if you restrain yourself, you won't get anything to eat".
The design of the bridge for wind was carried out based on extensive numerical analyses and wind tunnel tests: extreme wind climate analysis for typhoon, dynamic wind load (buffeting) analysis, computational fluid dynamics (CFD) analysis and sectional model tests etc.
Such turbulent flows may cause severe dynamic aeroelastic problems like wing and/or fin buffeting on fighter-type aircraft.
Special attention is placed on the determination of static deformation with consideration of geometric nonlinearity, and its influence on the dynamic modal properties, aerodynamic modal damping and buffeting response.
Research considering dynamic structural interactions in the presence of shock buffet is also highlighted, with a particular emphasis on the emergence of a frequency synchronisation phenomenon.
There are several different phenomena giving rise to dynamic response of tall structures under wind such as buffeting, vortex shedding, galloping and flutter.
The proposed methodology, based on the standard multi-mode approach for bridge buffeting, was used to compute the power spectral density of the buffeting modal forces and to derive the dynamic bridge response in the case that measurement errors in the aeroelastic loading were anticipated.
Just as she demonstrated in "Seabiscuit," Ms. Hillenbrand is a muscular, dynamic storyteller, never using an ordinary verb when a "teeming," "buffeted" or "porpoising" will do.
