EXPERIMENTAL BEHAVIOUR AND NUMERICAL MODELLING OF SMOOTH STEEL BARS UNDER COMPRESSION

Many existing reinforced concrete buildings located in seismic regions are characterised by internal steel reinforcement made of smooth bars and stirrups with inadequate spacing. These bars could be subjected to significant compression and eventually buckle. This paper deals with a comprehensive experimental campaign investigating the compressive behaviour of smooth bars for different values of the ratio L/D, L being the restraints distance and D the bar diameter. The stress-strain relationship is then modelled ranging from an elastic-plastic behaviour identical to that in tension (L/D=5) to the elastic buckling behaviour (L/D>20). The comparison between the experimental results and the outcomes of the model confirms the accuracy of the proposed stress-strain relationship.     

From Informal Recreation to a Geography of Achievement: Women's Soccer in South Australia

Since its inclusion amongst Olympic sports in the 1990s, women's soccer has grown impressively worldwide. Despite its rapid global expansion and growth in the number of playing participants, the sport has been neglected by geographers. In Australia, which is currently the fifth women's soccer country in the world as per registered players, the popularity of the sport has grown significantly in recent years. Perhaps even more strikingly, however, the approach to the sport has changed, to focus on the achievement of results. The shift in the purpose of women's soccer, from a solely social and recreational activity to an achievement sport, is a result of the increasing links between the local women's soccer systems and the global world of sport. The paper examines an exemplar of South Australia, and in particular the Adelaide metropolitan region. Here, in the last 30 years, women's soccer has evolved from a geography of foundation, defined by informal organisation and localised scope, to a geography of achievement, characterised by an institutionalised focus on the production of players, the introduction of higher-profile ‘sportscapes’, a broader pattern of clubs distribution, and a new set of connections with global women's soccer. The current geography of achievement links local and global women's soccer scenes. On the other hand, it funnels access to the achievement level of South Australian women's soccer to a limited central area of Adelaide's metropolitan region. The paper also draws attention to the part that social capital, and especially ‘bridging’ social capital, played in enabling the evolution of Adelaide women's soccer. The role of social capital as a contributing element of the development of sporting systems is a topic that deserves further investigation.     

The Spatial Organisation of Women's Soccer in Adelaide: Another Tale of Spatial Inequality?

Although sport is considered an important component of Australian society and a precious vehicle of social interaction, sports geography remains in many ways a neglected field of investigation. Nevertheless, geographical studies of sports can add valuable insights to more acknowledged geographical discourses. They can also contribute to regional sporting success. This paper analyses the current spatial organisation of women's soccer in Adelaide and outlines the unequal spatial expression of its recent professionally‐oriented approach, the achievement phase. A significant proportion of Adelaide's female population experiences limited opportunity to participate fully in the sport. The sport therefore fails to maximise its human resources and its spatial organisation constitutes a limit to the competitiveness of South Australian women's soccer as a system. The paper uses the concept of social capital to explore the unequal engagement of four sub‐regions in women's soccer. Many of the areas experiencing relative exclusion from women's soccer are the same ones that suffer the most from disengagement from the global economy. In those areas, socio‐economic disadvantage is matched by limited opportunities for self‐fulfilment through sport, and the effectiveness of social networks is weaker. This work aims to provide information for South Australian women's soccer institutions to foster enhanced equity in terms of access to the sport in metropolitan Adelaide. It also provides a base from which to investigate the reasons behind sub‐regional differences in the ability to produce quality players, knowledge that, if applied to these less productive areas, may contribute to the general enhancement of overall sporting outcomes.
