- In the first part of this study, five models from different country design codes such as Japan (AIJ 1985, JSCE 2009), USA (AASHTO-LFRD 2007, AISC 2010), China (GB50017-2003) and Europe (EC-4 2004) for predicting the shear capacity of headed studs are compared to the results from the modified push-out specimen used to represent the local behaviour, at full scale, of headed stud connectors within composite wall systems. Furthermore, the load-slip behaviour of the modified push-out specimen was compared with the expressions from Ollgaard et al. (1971), An and Canderwall (1996), Xue et al. (2008) and Abbass et al. (2011). Few experiments were performed by Saari and his co-workers on the modified push-out specimen due to cost limitations and no finite element modelling was included within their research. Within the available literature it was found that the only numerical study on this experimental study was conducted by Mirza and Uy (2010). The limitation of this paper was that no cracking and crushing propagation results were presented. Therefore, in the second part of this work the development of a detailed full scale three-dimensional finite element model is presented. The FE model was constructed in such a manner as to facilitate further parametric analyses.
