Abstract:

Eccentrically loaded Inverted L-shaped bridge piers have to be used in the construction of elevated highways bridges to avoid the existing obstacles in urban areas. However, their complicated seismic behavior has never been investigated in detail. In order to establish a rational seismic design method, the detailed behavior of the inverted L-shaped CFT (concrete-filled tubular) piers is examined by conducting shake table test on an elevated-girder bridge model supported on this type of piers.
