| Abstract: | This paper introduces shear failure research achievements,in which 5 groups of reinforced concrete beams with different sizes are tested under cyclic loading.In the research,shear behavior such as the hysteretic characteristics,the bearing capacity,the ductility and the energy-dissipating capacity are analysised.In addition,the influence rule of size effect is also studied in this paper.Results show that size effect on the shear capacity of reinforced concrete beam under cyclic loading is very obvious in de... |
