Eccentric compression testThe last example treats the failure of a concrete prism subjected to eccentric compression, testedby Debernardi and Taliano [41]. The geometry and loading set-up are shown in Figure 16(a).The specimen with a relatively large eccentricity of 36:8 mm is modelled by a thin layer of linearthree-dimensional elements, in order to circumvent the need for special stress-return algorithmsfor plane-stress conditions and at the same time keep the computational time low compared to aCopyright # 2005 John Wiley & Sons, Ltd.
