Table 15: Energy dissipation according to transverse rebar type (repeated load = 1235 kN) (unit = kN\(\cdot\)mm). of 65% of the ultimate shear resistance. It can be concluded that the energy dissipation models may be generated only depending on the load intensities of the repeated loads for the specimens adopted in this study.
