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.     

Competition,cooperation and resistance: women in the political field in Iraq

After the fall of Saddam Hussein's regime in April 2003 many women supported the process of transition and became active in political parties and coalitions. A wide range of groups were also formed which pursued women's rights agendas and, in many cases, included a call for peace and reconciliation and charity activities for women and children. However, female political action and the field of women's rights remain divided by the same multiple boundaries of belonging which affect Iraqi society itself; women operate in specific ethnic and denominational, local and regional settings, and they support nationalist, secularist, left‐wing or Islamist agendas. Women's rights—whatever the direction—can be of major or minor concern. This article outlines female political action and draws attention to the key issues which are discussed, in particular, by secular feminists in Iraq. In so doing, the article highlights how women in Iraq have not only lost, as a wide range of observers argue, but have also benefited from the restructure of the political landscape. Female political activists are still faced with old and new social, cultural, legal and political obstacles. The article argues that when women support narratives that leave men's superiority untouched, they are not simply victims of men or ‘false consciousness'; women either compete and cooperate, or they reject ideological narratives and power relations, while pursuing agendas of individual interest. Yet, despite competition among women and women's groups, and women's loyalty to agendas controlled by men, radical overtones that resist male domination can be heard— and should be supported.
