The effects of eyebar shape and pin/hole tolerance on its ultimate strength

Abstract

The present paper addresses the problem of the nonlinear elasto-plastic behaviour of an eyebar or pin-connection under increasing quasi-static load with reference to the effects of shape and pin/hole tolerance on the ultimate strength. The study uses ABAQUS to model the geometric and material nonlinearities of the eyebar and the boundary nonlinearity due to the increasing contact between the pin and plate-around the hole. The results are compared with those of other investigators and are found to be accurate. The effect of shape on ultimate strength is found to be limited. For an eyebar with given hole and plate dimensions, there appears to be an approximately linear reduction in strength due to an increase in pin/hole tolerance within the range of parameters investigated. © 1993.
