Average Crack Spacing of Overlay-Strengthened RC Beams
No full textThe research is focused on evaluating the average crack spacing of overlay-strengthened reinforced concrete (RC) beams. The current equations in different structural codes for predicting the average crack spacing of RC beam with multilayered-reinforcing bars is proved to be inapplicable for overlay-strengthened RC beam, although these two kinds of beams are both with reinforcement in multi-layers. Therefore, a simple, practical and new analytical model that is capable of predicting the average crack spacing of overlay-strengthened beams is developed. An overlay-strengthened beam element is analyzed based on equilibrium and compatibility equations to formulate the average stresses of concrete, overlay and tension reinforcement. A series of verification comparisons with the experimental investigations, which involved various types of beam elements, are performed to verify the validity and reliability of the model. The proposed model performs satisfactorily with respect to measured response from the experimental database

From the 'Rescue of the Nation State' to the Emergence of European Spaces. EUIJ-Kansai Workshop on "New Research Horizons of the History of European Integration", May 10, 2008, Toyonaka (Osaka)
No full textThe aim of this paper is to make some contribution to the discussion on the future direction of the historical research on the European integration processes. What I intend to do here is, broadly, to link the contemporary European studies to the Historical studies, and concretely, to emphasise the transnational dimension of European integration. This exercise should be read as presenting my "wish list" to the Integration Historians
A Design Proposal for Concrete Cover Separation in Beams Strengthened by Various Externally Bonded Tension Reinforcements
No full textPrevious research has shown that the application of externally bonded reinforcements (steel plates, fiber-reinforced polymer (FRP) laminates, overlays, etc.) to strengthen reinforced concrete (RC) beams can lead to brittle debonding failures before the ultimate load is reached. The aim of this study is to develop an analytical approach for the flexural strengthening of existing structures using various types of external reinforcements and predicting the debonding failure. In this study, an analytical model is developed to predict concrete cover separation failure in beams with overlay strengthening that is also applicable to strengthening using other reinforcements, such as steel plates and FRP laminates. An experimental database with various types of beam specimens is used to verify the model's validity and reliability. A concept for determining the effective strengthening capacity in a strengthening design is presented and the main parameters affecting the strengthening capacity are investigated. Finally, a design proposal is presented for the flexural strengthening of RC beams with respect to concrete cover separation failure. This proposal contributes to the application of external flexural strengthening in practical design
