Abstract

In this study, hysteretic behavior of RC beams with and without significant
gravity load effects are investigated. To this purpose, an experimental program is
carried out in which gravity loads are applied by force controlled test procedure
whereas cyclic loads are applied by displacement controlled test procedure. The
results of tests with gravity load effect are compared with the results of control
specimens with increasing displacement loading profile. Experimentally observed
damage states and deformation demands are compared with the respective values
proposed by Turkish Seismic Design Code. It is found that, the loading procedure
with significant gravity load effect leads to the formation of unidirectional plastic
hinges. Besides, the deformation capacities of the specimens are found to be
much higher than the code based deformation capacities.
