Damage of adjacent bridge structures due to relative responses, such as pounding and unseating, have been observed in many earthquakes. The isolators in bridge structures are effective in mitigating the induced seismic forces. However,... more
My brief understanding on Non Metallic expansion joints
This patent describes an Apparatus for preventing temperature-induced tension failure of a tubing string of a producing subterranean well extending from a packer set in the well above a formation producing heated fluids to a fixed... more
It gives a basic knowledge of the Expansion joint and its components.
As pontes e viadutos são nomenclaturas pertencentes às OAEs e estruturas utilizadas para transpor o tráfego de veículos, pessoas e trens. Com o objetivo de vencer um vão, seja este composto por cursos d’água, no caso de pontes, ou... more
The pounding responses of the expansion joint in a curved ramp bridge under earthquake conditions. Long term effects of such seasonal temperature changes develop stresses and deformation in the building. Concrete creep and shrinkage... more
Bridges are traditionally built with expansion joints at the ends to allow for longitudinal displacements of the superstructure due to temperature variations. Thus, most conventional bridges possess expansion joints and bearings, which... more
