The measuring points of the longitu

The measuring points of the longitudinal reinforcement and stirrup strain were mainly arranged via the reinforcement of the plastic hinge region at the bottom of the bridge column. The strain gauges for longitudinal reinforcement were arranged on the four faces of the column at positions corresponding to 50, 200, 400, 600, and 1,200 mm above the bottom of the column. The strain gauges for the stirrup were arranged on the four faces of the column at positions corresponding to 50, 100, 200, 300, and 400 mm above the bottom of the column. Figures 7–9 show the measuring point layout of reinforcement and concrete strain.
