摘要

As the steel grid reinforced earth walls become higher and larger, the required reinforcement length becomes longer, and subsequeutly it is indispensable to connect reinforcements from the economical viewpoint. An effective mechanical connection between steel grid reinforcements has already been proposed by the authors. In this paper, the failure strength and failture mode of mechanical connections between steel grid reinforcements are examined, changing diameters of connection bars. The effect of connection bar stiffness on the failure strength of mechanical connections are discussed based on tension test data. As the results, the connection bar stiffness plays an important role on the failure strength and failure mode of the mechanical connections. The failure strength increases as increasing the diameter of connection bar, however, a suitable diameter of connection bar exists for the mechanical connection from the viewpoint of failure mode.
