Abstract
A connector for use in constructing an earth stabilizing structure with the capability of yielding horizontally to excessive impact loads. The connector comprises a slotted metal plate which may be used to form connections along a horizontal reinforcing member or between the reinforcing member and a facing element. The slot has a larger transverse dimension at one end and narrows toward its opposite end. A bolt, pin or connecting arm having a cross-sectional dimension which allows for insertion into the widest end of the slot, but which provides resistance upon movement toward the opposite end of the slot, is inserted through the slot, providing a connection between the metal plate and another component of the earth stabilizing structure. As the bolt, pin or connecting arm is moved toward the narrow end of the slot, it engages the edges of the slot and provides full design strength by mechanical interference. As an additional load beyond the anticipated design load is imposed, the bolt, pin or connecting arm is forced toward the narrow end of the slot, deforming the edges of the slot as it moves. After slipping, the connection returns to a condition of safe stress. The metal plate …
