The behaviour and design of bolted moment-connections between cold-formed steel members, formed by using brackets bolted to the webs of the section, is considered. The particular problem of the moment-capacity of such joints being lower than that of the cold-formed steel sections being connected because of web buckling, caused by the concentration of load transfer from the bolts, is addressed. In this paper, a combination of laboratory tests and finite element analyses is used to investigate this mode of failure. It is demonstrated that there is good agreement between the measured ultimate moment-capacity and that predicted by using the finite element method. A parametric study conducted using the finite element model shows that the moment-capacity of a practical size joint can be up to 20% lower than that of the cold-formed steel sections being connected. Web buckling so-caused must therefore be considered in the design of such connections. (C) 2003 Elsevier Ltd. All rights reserved.

This paper addresses the potential resurgence of post imperial “dependency theory” of the 1960s and 1970s. Suggesting that the initial premise of the theory was just – the article proposes the reworking of the theory in order to incorporate globalisation processes – namely the importance of global capital generated by Multi National Corporations. By considering that capital is now the “core” we have the idea of a much wider catchment of states “dependent” on global capital. Using Ireland as an example therefore, the article pursues the idea that a dependent state’s ability to implement CSR legislation is inhibited by the constraints of capital.

Policy documents are a useful source for understanding the privileging of particular ideological and policy preferences (Scrase and Ockwell, 2010) and how the language and imagery may help to construct society’s assumptions, values and beliefs. This article examines how the UK Coalition government’s 2010 Green Paper, 21st Century Welfare, and the White Paper, Universal Credit: Welfare that Works, assist in constructing a discourse about social security that favours a renewal and deepening of neo-liberalization in the context of threats to its hegemony. The documents marginalize the structural aspects of persistent unemployment and poverty by transforming these into individual pathologies of benefit dependency and worklessness. The consequence is that familiar neo-liberal policy measures favouring the intensification of punitive conditionality and economic rationality can be portrayed as new and innovative solutions to address Britain’s supposedly broken society and restore economic competitiveness.
