摘要

Yield line mechanism analysis has been widely used to study steel members and connections that involve local collapse mechanisms. In the application of the yield line method, a fundamental requirement is to determine the reduced plastic moment capacity of an inclined yield line under axial force. This paper reviews various theories dealing with inclined yield lines. Comparisons between these theories are presented. The paper also summarizes some basic or simple yield line mechanisms that may be adopted directly to solve more complicated problems. The application of yield line mechanism analysis is included, covering steel plates, open-section members, closed-section members, void-filled members, welded connections and bolted connections. It is shown that this method can be used to study post-collapse behaviour, load-carrying capacity, ductility, rotation capacity and energy absorption.
