- An analytical study on the seismic behavior of multi-span continuous bridges with buckling-restrained braces
Abstract
This study is aimed at investigating the effect of damper braces for improving seismic behavior of multi-span continuous bridges. For this purpose, two arrangements are devised. One way is to connect the girder and the top of pier by buckling-restrained brace. Another way is to connect the girder and the base of pier by buckling-restrained brace. Then elasto-plastic response analyses are carried out to confirm the influence of differences between two ways. As a result, it is found that maximum response displacements of the girder and the damage of steel piers are significantly reduced by installing the buckling-restrained braces between the girder and the base of pier. Finally the demand of a buckling-restrained brace is discussed.
