Bridge (Buffeting etc.)

Computer Simulation of Buffeting Responses for Long-span Continuous Rigid-frame Bridge with Over-height Pier

The continuous rigid frame bridges are more sensitive to wind action with the increase of bridge span and pier height. In order to calculate the wind induced buffeting responses, the fluctuating wind field at bridge site are simulated by harmonic synthesis method and the wind loads are also derived based on the simplified quasi-steady theory, the time-history dynamic responses of the bridge are...

Wind buffeting of large telescopes.

Unsteady wind loads due to turbulence within the telescope enclosure are one of the largest dynamic disturbances for ground-based optical telescopes. The desire to minimize the response to the wind influences the design of the telescope enclosure, structure, and control systems. There is now significant experience in detailed integrated modeling to predict image jitter due to wind. Based on thi...

Analysis of Long Span Bridge Response to Winds: Building Nexus between Flutter and Buffeting

In current bridge aeroelastic analysis frameworks, predictions of flutter instability and buffeting response to wind fluctuations are treated as two separate procedures. The flutter instability is analyzed through the solution of a complex eigenvalue problem, offering information on how the self-excited forces influence bridge dynamics, especially the modal damping, and eventually drive the bri...

Introduction etc

Bilateral and multilateral development cooperation agencies are to an increasing extent promoting and adopting a sector-wide approach (SWAp) in their development cooperation. The Swedish International Development Cooperation Agency (Sida), for example, joined their first sector-wide approach cooperation in the late 90s, and today they are involved in SWAps in countries in Africa, Asia and Latin...
