本文采用E-Defense软件对某大型钢筋混凝土桥柱进行了三维振动台试验。模型为典型的钢筋混凝土柱，建于20世纪70年代的日本。在1995年日本神户地震中，这种类型的柱的倒塌是造成大面积破坏的主要原因之一。一个7.5米高，直径1.8米的柱状模型被1995年神户地震中记录的近场地面运动激发了两次。给出了实验响应和分析相关性。
This paper presents a 3D shake table experiment on a large scale reinforced concrete bridge column using E-Defense. The model was a typical reinforced concrete column which was built in the 1970s in Japan. Collapse of this type of column was one of the major causes of the extensive damage during the 1995 Kobe, Japan earthquake. A 7.5 m tall, 1.8 m diameter column model was excited twice by a near-field ground motion which was recorded during the 1995 Kobe earthquake. Both experimental response and analytical correlation are presented.
