Figure 11. Measured load-deflection histories exhibit sudden drops in force as the post fails in the tensile region. Graph.

This graph shows two distinct lines, the first colored red and labeled Test 418, Grade 1 and the second colored blue and labeled Test 1420, DS-65. The vertical axis of this graph ranges from 0 to 80 and represents Force (kilonewtons) while the horizontal axis ranges from 0 to 250 and represents Deflection (millimeters). Both lines begin at the points of zero on the vertical and horizontal axes.
