Seismic vulnerability assessment of RC curved bridges piers subjected to bidirectional earthquake

چکیده

Curved beam bridge is a kind of irregular structure, which has the advantage adapting to complex terrain, but it more vulnerable damage than regular under earthquake. This paper investigates vulnerability curved continuous girder bridges action bidirectional earthquake horizontal earthquake, and difference between side pier intermediate analyzed. Fragility assessment performed using an incremental dynamic analysis method subjected wide range as-recorded sequences. A proper engineering demand parameter (EDP) can result in most probability failure at employed this study determined. Result indicates that only considering unidirectional seismic input will underestimate response potential not accurate for performance evaluation bridge. also shows higher pier, serious failure, smaller two piers.

Seismic Damage Assessment of RC Buildings Subjected to the Rotational Ground Motion Records Considering Soil-Structure Interaction

The significance of the seismic rotational components have been overlooked in the seismic evaluation of structural behavior. As researchers have measured seismic components more accurately using sensitive rotational velocity sensor, it was observed that the magnitude of rotational components is considerable and could not be neglected. Hence, some parts of seismic damage or failure of structures...
