| Abstract: | The strain characteristics and crack patterns of four specimens of reinforced concrete eccentric beam-column joints with spread-ended beam under reversed cyclic loading are investigated by using the nonlinear finite element method. The performance of the joints are studied as the width of the spread-ended beam varies,and the conditions of displacement of plastic hinge at the end of the beam are discussed. The results of finite element analysis are compared with the actual failure situation of the specimens,and the method of determining the position of the plastic hinge is presented. |
