Invited Paper SEISMIC PERFORMANCE OF A FLEXURAL FAILURE TYPE REINFORCED CONCRETE BRIDGE COLUMN BASED ON E-DEFENSE EXCITATION

摘要

This paper presents a 3D shake table experiment on a large scale reinforced concrete bridge columnnusing E-Defense. The model was a typical reinforced concrete column which was built in the 1970s innJapan. Collapse of this type of column was one of the major causes of the extensive damage during then1995 Kobe, Japan earthquake. A 7.5 m tall, 1.8 m diameter column model was excited twice by a near-fieldnground motion which was recorded during the 1995 Kobe earthquake. Both experimental response andnanalytical correlation are presented.
