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...

Adaptive Space Frame Analysis: Part I, a Plastic Hinge Approach

This is one of two companion papers presenting new procedures for the efficient largedisplacement analysis of steel frames in the elasto-plastic range. Emphasis is given in this paper to the development and improvement of a plastic hinge approach utilizing the concept of adaptive mesh refinement. In the companion paper, such a concept is discussed in the context of a more accurate approach acco...
