Characterization, Experimental Investigation, and Application of a Sliding Controlled Spherical Bearing

摘要

In this study, a customized spherical bearing combined with a set of sliding-control cables was developed. To verify the characteristics of the developed bearing, an experimental study on both longitudinal and transverse direction was conducted. Test results confirmed the effectiveness of the proposed design. To simulate this system, a 2-link-element simulation method was presented. Comparison showed that the numerical simulation method can match the test results of the bearing properly. Furthermore, a numerical case study featuring an extradosed bridge was presented in which the results implied that the proposed design can control the relative displacement between the girder and pier effectively.
