Sort By:   

  Experiment-1: Specimen I-1: Column with Interlocking Spiral Reinforcement and Larger Cross-Section Dimensions Ratio
Dates: August 31, 2006 - September 06, 2006
Description: Shake table tests were conducted on interlocking spiral columns constructed based on the Japan Road Association and Caltrans design criteria. The specimens were subjected to several levels (percentages) of the ground motion records from the JR Takatori...

  Experiment-2: Specimen I-2: Column with Interlocking Spiral Reinforcement and Smaller Cross-Section Dimensions Ratio
Dates: August 31, 2006 - September 06, 2006
Description: A 1/6 scaled interlocking spiral reinforcement column was tested on a shake table at several ground motion levels. This specimen had a ratio of short to longer cross-sectional dimensions of 0.64. The center-to-center distance was 1.3 times the radius...

  Experiment-3: Specimen R-1: Rectangular Column with Hoop Reinforcement and Larger Cross-Section Dimensions Ratio
Dates: August 31, 2006 - September 06, 2006
Description: The third out of four specimens tested was a column rectangular in cross-section with typical hoop reinforcement. It had a 0.7 ratio of short to longer cross-sectional dimensions and the tie spacing was 37mm. It was also designed and constructed based...

  Experiment-4: Specimen R-2: Rectangular Column with Hoop Reinforcement and Smaller Cross-Section Dimensions Ratio
Dates: August 31, 2006 - September 06, 2006
Description: The final specimen tested was specimen R-2. This was a rectangular column with hoop reinforcement, with a ratio of short to longer cross-sectional dimensions of 0.64 and a tie spacing of 37mm. This specimen was also constructed based on the Japan Road...
