Modelling and Seismic Response Analysis of Italian Code-Conforming Base-Isolated Buildings

ABSTRACT

This paper reports on results of nonlinear analyses performed within the RINTC project on an RC building isolated with different systems (High Damping Rubber Bearings, High Damping Rubber Bearings and Flat Sliding Bearings, Friction Pendulum System) and designed according to the Italian design code. The seismic response has been evaluated under different seismic input levels of two sites with different hazard and by considering two Limit States: Global Collapse and Usability-Preventing Damage. The influence of seismic stoppers and modelling uncertainties is also evaluated. Results permit to compute the implicit collapse risk and to identify critical aspects of current design procedures.     

Women’s changing domestic responsibilities in neoliberal Africa: a relational time-space analysis of Lesotho’s garment industry

Since 2001 when Lesotho embraced the neoliberal African Growth and Opportunities Act that offers preferential access to the US market, its garment industry has expanded dramatically to become the nation’s leading employer. Elsewhere, large-scale employment of women in low-paid factory jobs has entailed spatial restructuring of gender and age relations. Lesotho is a distinctive context, with socio-spatial relations historically adjusted to male labour migration, high levels of contemporary male unemployment and alarming AIDS prevalence. Based on semi-structured interviews with 40 female factoryworkers and 37 dependents, this article applies a relational time-space analysis to explore how financial and spatio-temporal aspects of factory employment articulate to alter women’s relationships with those for whom they have culturally determined responsibilities: their children, those suffering from ill health and their (generally rural) home communities. The analysis highlights that such employment is not merely adding to women’s responsibilities, but transforming how they are able to undertake social reproduction, as practical, social and emotional roles are converted to largely financial obligations.     

Castles,castellans and the structure of politics in Poitou, 1152– 1271

By the middle of the twelfth century Poitou had been divided into small units of local control, known as castellanies. A castellany was the territory surrounding a castle; within it the castellan exercised military, judicial and economic powers. Between 1152 and 1271 the control of castles in Poitou experienced a development of three stages, moving from single-castellany holdings by the province's fifty leading families via regional lordships pieced together by four of these families to country-wide hegemony by the count. The progressive consolidation of castle-holding corresponded to the development of political life. The chaotic political conditions of the second half of the twelfth century were replaced by the leadership of the regional lords after 1200, which in turn gave way to the unchallenged authority of the count after 1242. The logic of this tripartite development explains the achievement of Alphonse of Poitiers, count from 1241, in turning Poitou from a region of chronic turbulence into a well-governed country. This paper emphasizes the role of the regional lords as the bridge between extreme fragmentation of authority and effective centralization.

From Herders to Wage Laborers and Back Again: Engaging with Capitalism in the Atacama Puna Region of Northern Chile

Towards the end of the nineteenth century, indigenous Atacameño society transited from an agro-pastoralist to a more diversified capitalist-based economy due to a growing mining industry in northern Chile. The puna herders engaged in the new capitalist order as wage laborers in sulfur mines and llareta (Azorella compacta) exploitation companies. In this article we show how indigenous knowledge acted as cultural capital that enabled the herders to work as laborers. This operation led to horizontal treatment among the different agents in the taskscape that those “herder-laborers” inhabited, including those incorporated by industrial capitalism.
