- Eleven reinforced concrete cantilever beam specimens were constructed and subjected to different load histories to study the effect of load history on the total energy dissipation capacity of flexural members under inelastic cyclic loading. Major variables included in this study were load history and maximum shear stress applied to the members. Four different load histories and three levels of maximum shear stress were used. Both variables were found to significantly affect the total amount of energy a specimen was able to dissipate prior to failure. The results of these tests indicated that, if member maximum displacement did not exceed 2 percent of its shear span length, severe deterioration of member shear strength would not take place within the number of cycles of load that a structural member could reasonably be expected to experience during a severe earthquake.
