Abstract

This study mainly focused on the experimental evaluation of pipe-shape shear connectors for multi-beam box girder bridges. The multi-beam box girder bridges are a structure to the integration with the box girders placed adjacent to each other. They are generally connected by shear keys and loop joints to resist the shear force at their interfaces, and lateral tendons for applying the compression force. However, if the integration effect decreases with time, the relative deflection between adjacent girders occurs and it causes the reflective cracks on the deck along the interfaces. Furthermore, the efficiency of constructing multi-beam box girder bridges decreases when loop joints are used because it is complicated to form the required connections using couplers. Therefore, this study evaluated behavior of pipe-shape shear connectors which are superior in workability and ductility than loop joints by push-out tests and pull-out tests.
