All estimates associated with moment and shear computed based on actual material properties.
: initial crack load (measured), : yield load by Park’s method (measured), : peak load (measured), : yield displacement (measured), : peak displacement (measured), : failure displacement (measured), : drift corresponding to the yielding, : drift corresponding to the yielding, : ductility (/ = deformation capacity), and : strength increase ratio.
