The shear failure of railway bridge piers has become the main feature of modern bridges. In order to study the shear resistance of railway bridge piers, three models were designed in this paper, including two piers model with a ratio of 1:5 based on Chenglan Railway bridge prototype piers and a test research model. Through the pseudo-static test study on the shear resistance of piers, the failure process of the specimen was given. It was indicated that that A1 and A2 specimen were typical bending failure and possessed enough ductility. And A3 specimen was typical flexure-shear failure. Before loading to yield displacement, stirrup provided little shear strength. After loading to yield displacement, the shear strength provided by stirrup increased gradually with the development of cracks. When the stirrup yielded, its restraint to the core concrete was weaken rapidly, which resulted in the rapid destruction of the bridge pier.
