小尺寸钢筋混凝土梁模型实验研究

Under the limit of equipment and budget of experiment, it is necessary of using small size specimen to study the performance of reinforced concrete components. In this paper, the research on model test of small specimen was carried out. First, the size of the small specimen was decided due to the limitation of equipment. Then, the steel bars in small specimen were designed. Finally, the four point bending test of the small specimen of concrete beam was carried out. The result shows that the typical failure of concrete beam could happen and the small specimen can be used to study the mechanical performance of concrete beam.
