Prediction of Yield‐line Geometries for Arbitrary Simply Supported Slabs

Abstract

The calculation of limit loads of slabs using the yield-line theory requires the assumption of a kinematical collapse mechanism. In recent years several approaches concerning the optimization of predefined mechanisms have been introduced. Usually they contain semi-automatic procedures which depend on user-defined yield-line predictions. This paper presents a systematic approach and a numerical procedure to find yield-line predictions for arbitrary all-side supported slabs.
