Shear resistance analytical evaluation for RC beams with transverse reinforcement with two different inclinations
2020
An analysis-oriented mechanical model for shear strength evaluation of Reinforced Concrete (RC) beams with transverse reinforcement with two different inclinations, which required a numerical analysis, is turned into a design-oriented analytical model that can easily be utilized for practical purposes. The model assessed the shear resistance, according to the “lower-bound solution”, employing a numerical procedure that maximizes the element shear strength varying the stresses in the two sets of transverse reinforcement and the magnitude and inclination of the web concrete compressive stress field. The model is formulated with the aim of representing an extension of Eurocode 2 framework to R…
A Methodology to Detect the Deviations of the Project s Budget Compared to Market Prices
2015
[EN] The budget of a project reflects the cost of the investment needed to build an infrastructure, install a system or acquire new materials or supplies. A well-formulated budget in accordance with market prices, allows contractors to prepare offers according to their technical, economic and financial characteristics. On the other hand, it avoids current philosophies that aim to get the contract at any price. Philosophies subsequently used to point out problems and claims during the execution of the project (contradictory prices, delays, etc.) in order to recover some or the entire economic bid carried out during the tendering. In this paper a simple and fast methodology is developed to ch…
A contested financial frontier: banking and empire building in Eritrea, c.1952–73
2021
AbstractThis article provides an account of the relationship between imperial Ethiopia and Eritrea in the realm of banking governance from the start of the federation to the last years of the imperial regime. It looks in particular at the relationship between the Ethiopian administrations and an Italian bank, Banco di Roma, which had its headquarters in Eritrea from 1948 to 1967 before moving to Addis Ababa. The struggle for control of the economic flows generated by the Italian bank is an index of the changes in centre–periphery linkages between Addis Ababa and the sub-regional centre of Asmara. Archival evidence highlights the multifaced nature of Ethiopian governance and the role perform…

Supporting value creation in SMEs through capacity building and innovation initiatives: the danger of provoking unsustainable rapid growth
2009
Value creation comes in many guises, and may be achieved through expansion and efficiency, innovation and novel processes, and closer alignment with customer needs. This article examines the real dangers to firms, especially small firms, which pursue very ambitious capacity growth plans in order to chase market opportunities. Case analysis has unearthed a new phenomenon, which might be termed ‘business gigantism’ – a situation of rapid and unsustainable growth that places severe strains on the firm. This article briefly recounts two case studies where small firms secured substantial funding to support rapid expansion – in both cases via public agencies. In each case, funding was justified b…
Public-Private Partnerships: Agency Costs in the Privatization of Social Infrastructure Financing
2019
Public-private partnerships (PPPs) have been subjected to considerable public debate. In particular, this debate has concerned PPP financing and its implications. Using insights from agency theory, this study aims to develop a theoretical understanding of PPP financing. The following research question is investigated: How does the privatization of financing decrease or increase agency costs in social infrastructure PPPs? A comparative case study consisting of four Norwegian PPP projects with different financial configurations is undertaken. The findings suggest that the private sector is risk averse, increasing the cost of capital. In addition, private financing does not seem to have the i…
Assessing price clustering in European Carbon Markets
2012
Abstract The presence of price clustering in markets is taken as a sign of market inefficiency that can influence trading strategies. In this paper, we study the presence of a concentration in prices in carbon futures markets. Specifically, we analyze the European Carbon Futures Markets and test for evidence of preference for certain prices above others. Our results reveal the strong presence of price clustering in the carbon market at prices ending in digits 0 and 5. These findings support the attraction hypothesis, which endorses a significant clustering on gravitational prices, but also backs the negotiation hypothesis, which advocates greater clustering when trading costs are higher.
Design of RC joints equipped with hybrid trussed beams and friction dampers
2021
Abstract The challenge of this research consists in the first attempt to apply a dissipative friction connection to beam-to-column joints with semi-prefabricated Hybrid Steel-Trussed Concrete Beams (HSTCB) and RC pillars cast in-situ. Nowadays, HSTCBs are widely adopted in civil and industrial buildings and, therefore, it is required to evaluate their compliance with the capacity design criteria and their seismic energy dissipation capability. However, the design of the reinforcement of such beams usually lead to the adoption of large amount of steel within the panel zone which becomes potentially vulnerable to the effects of seismic cyclic actions and dramatically reduce the dissipation ca…
Modeling the energy and environmental life cycle of buildings: A co-simulation approach
2017
Abstract Building simulation is currently looking towards interdisciplinary experiences, aiming to the integration of simulation tools in different technical domains. At the same time, the interest of the building community to high performance buildings has also strengthened the interest on Life Cycle performances of such buildings, due to the reduction in their operational stage impacts. In this context, the paper proposes an integration of building simulation and Life Cycle Assessment through the programming of a TRNSYS component. It can perform Life Cycle Assessment studies, while having as output as well energy balances and energy and environmental payback times. Currently, the tool is …
A Review of Key Performance Indicators for Building Flexibility Quantification to Support the Clean Energy Transition
2021
The transition to a sustainable society and a carbon-neutral economy by 2050 requires extensive deployment of renewable energy sources that, due to the aleatority and non-programmability of most of them, may seriously affect the stability of existing power grids. In this context, buildings are increasingly being seen as a potential source of energy flexibility for the power grid. In literature, key performance indicators, allowing different aspects of the load management, are used to investigate buildings’ energy flexibility. The paper reviews existing indicators developed in the context of theoretical, experimental and numerical studies on flexible buildings, outlining the current status a…
