Modeling and Seismic Response Analysis of Italian Code-Conforming Reinforced Concrete Buildings

ABSTRACT

This study investigates the seismic response of reinforced concrete buildings designed according to the current Italian building code. Number of stories, site hazard, presence and distribution of masonry infill panels, and type of lateral resisting system are the key investigated parameters. The main issues related to design and modeling are discussed. Two Limit States are considered, namely Global Collapse and Usability-Preventing Damage. The main aim of the study is a comparison between the seismic response of the buildings, investigated through nonlinear static and dynamic analyses. Irregularity in the distribution of infill panels and site hazard emerge as the most influential parameters.     

TheConvergence of the Italian Regions and Unemployment: Theory and Evidence

We explore the links between the halt of the convergence process of Italian regions at the beginning of the 1970s and the increase in regional unemployment dispersion. We consider a neoclassical exogenous growth model with an imperfect labor market and show that during the transitional dynamics the imperfections of the labor market negatively influence the output growth rate. In particular, the model implies that centralized bargaining is likely to set a national minimum wage that is too high with respect to the labor productivity of the less developed regions, resulting in a negative impact on their per capita output growth. We test the implications of the model on a regional panel data set using the GMM framework. Both our market distortion measure and the unemployment rate are found to significantly lower the growth rate of per capita output.     

Italian welfare as seen from the standpoint of the International Labour Organization (1944–68)

The evolution of Italian welfare cannot be properly understood unless it is viewed within a scenario that goes beyond the national one and accounts for both the different state experiences and geopolitical and supranational conditioning. By adopting a supranational standpoint, the aim of this article is to offer some new sources of reflection on the role of the International Labour Organization (ILO) in conditioning and assessing the Italian welfare model starting from the end of the Second World War to the 1960s. I intend to linger both on the ILO’s role in urging the development of modern social security systems and the adoption of certain welfare measures and on the representation and assessments carried out by the ILO regarding the actual development of the Italian welfare state.
