Moment‐Rotation Curves for Bolted Connections

Abstract

A physically based mathematical model that can predict the moment‐rotation relationships of bolted extended end‐plate eave connections, using the connection dimensions as inputs is presented. The model recognizes the bounds within which the relationship must lie, viz. the initial (elastic) stiffness, the plastic moment capacity and the strain‐hardening stiffness of the connection. Comparison is made to a series of test results for a range of bolted end‐plate moment connections.
