The effectiveness of viscous dampers in the seismic retrofitting project of an Italian cantilever bridge

The viscous anti-seismic devices, also called “viscous dampers”, are frequently used to improve the seismic response of structures and in particular of bridges. Unlike other anti-seismic devices, the viscous dampers are characterized by a considerable damping and yield capacity which allows to dissipate a rate of energy induced by the seismic action and to contain, together with the displacements, also the stres- ses that arise in the structural elements. Due to their performance characteristics, the viscous dampers have been used within a huge seismic retrofitting project of an Italian bridge located on A14 highway Bologna- Taranto in the Abruzzo Region, which is the case study outlined in this paper

New procedure for bridge analysis of heavy vehicles transit (NTEO)

Infrastructures such as Bridges and Viaducts can be significantly affected by the effects of Heavy Vehicles (H.V.) transit, which represent an unexpected overload, potentially greater than design stand- ard loads. Moreover, Heavy Vehicle transit authorization is a very onerous activity; as a matter of fact, safety check valuations of all the involved structures are required in reasonable time. NTEO (“New T.E. Online”) is a new H.V. transit authorization procedure, which aims to provide a semi- automatic method for estimating the assessment of several existing structures in the process of H.V. transit. The methodology is focused on the general approach of influence lines, related to the most critical sections of the examined structures (e.g. bending moment in the beam mid-span or shear in the beam support). The traditional definition of influence lines in bridge design is based on the common criteria of transversal distribution of the actions (Courbon, Massonet). Contrastingly, the NTEO procedure uses influence lines extrapolated from an explicit F.E.M. model of each structure involved in the H.V. transit. This choice requires the implementation of many calculation models, but at the same time leads to much more accurate and reliable results than the simplified theories of transversal distribution, especially when these theories can’t be applied. Once models have been created, it is possible to reuse the influence lines for different load scenarios, facili- tating authorizations for the following Heavy Vehicle transit

The effect of heat treatment and impact angle on the erosion behavior of nickel-tungsten carbide cold spray coating using response surface methodology

This study elucidates the performance of cold-sprayed tungsten carbide-nickel coating against solid particle impingement erosion using alumina (corundum) particles. After the coating fabrication, part of the specimens followed two different annealing heat treatment cycles with peak temperatures of 600 °C and 800 °C. The coatings were examined in terms of microstructure in the as-sprayed (AS) and the two heat-treated conditions (HT1, HT2). Subsequently, the erosion tests were carried out using design of experiments with two control factors and two replicate measurements in each case. The effect of the heat treatment on the mass loss of the coatings was investigated at the three levels (AS, HT1, HT2), as well as the impact angle of the erodents (30°, 60°, 90°). Finally, the response surface methodology (RSM) was applied to analyze and optimize the results, building the mathematical models that relate the significant variables and their interactions to the output response (mass loss) for each coating condition. The obtained results demonstrated that erosion minimization was achieved when the coating was heat treated at 600 °C and the angle was 90°

Investigation of the Effect of Low-Temperature Annealing and Impact Angle on the Erosion Performance of Nickel-Tungsten Carbide Cold Spray Coating Using Design of Experiments

This study investigates the solid particle erosion performance of cold sprayed tungsten carbide-nickel coatings using alumina particles as erodent material. After coating fabrication, specimens were annealed in an electric furnace at a temperature of 600 °C for 1 hour. The coatings were examined in terms of microhardness and microstructure in the as-sprayed (AS) and annealed (AN) conditions. Subsequently, the erosion tests were carried out using a General Full Factorial Design with two control factors and two replicates for each experimental run. The effect of the annealing on the erosion behavior of the coating was investigated at the two levels (AS and AN conditions), along with the impact angle of the erodents at three levels (30°, 60°, 90°). Finally, two regression models that relate the impact angle to the mass loss were separately obtained for the two cold spray coatings

Investigation into energy dissipation in equal channel angular extrusion

The field of energy absorption is definitely one the most important in engineering design, as many types of static and dynamic structures, designed and built for different purposes and tasks, require energy absorption capabilities under loading conditions. This thesis is aimed at the introducing experimental and theoretical analyses of a novel and revolutionary technique to dissipate unwanted energy in engineering systems. An extensive literature review on existing energy absorbers was undertaken in relevant application fields such as structural and personal protection. Hence, devices attached to buildings and designed to dissipate energy due to severe earthquakes have been discussed and compared. Types considered, in this review, are mainly based on friction, viscoelasticity and material yielding mechanisms. Furthermore, methodologies to strengthen structures against impacts such as those used in armoured walls are described, and their capabilities assessed. In addition techniques to protect the human body against dangerous loads were reviewed, and important issues for chest and head protection, leg defences in football and safety in motorcycles have been investigated. Experimental results about energy absorption in crash tests have been studied. Also, as an example the use of current technologies to dissipate energy during landing operations in aircrafts have been considered. A classified chart of energy absorption devices in different applications has been produced and referenced. In general most energy absorption devices were shown to be capable to eventually dissipate dangerous and unwanted energy, but poor reusability and predictability after impact were not part of the design process. The research base in this thesis is a novel energy dissipation technique capable of designing Universal Reusable Energy Absorption Devices (UREAD). This technique exploits the principles and working mechanisms that are used in extrusion of deformable materials through intersecting channels. Such mechanism of deformation is known in literature as Equal Channel Angular Extrusion (ECAE). ECAE is one of the severe plastic deformation processes. A theoretical analysis of internal pressure and stresses developed at the interface with the tools has been presented for channels of different geometrical parameters. In addition, energy absorption capabilities have been analysed by the Upper Bound ii method. Also, a numerical solution based on the implementation of the Finite Element Analysis, in ANSYS commercial package was obtained to show the intensity of stress distribution in the deforming material and the tools surrounding it. UREAD devices of different dimensions and geometries were designed, manufactured and tested using an experimental set up constructed for this work. Circular and square cross-sectional channels were tested using various deformable materials. Experimental results were compared with theoretical distributions, and several analogies were highlighted and discussed. Special tools were designed and manufactured to study experimentally the normal stresses at contact surfaces using the so called “Pressure Pin Technique”. Also, an experimental apparatus has been built to simulate the potential implementation of UREAD devices against the occurrence of heavy impacts and the effect of the energy absorber was experimentally measured at the instant of ground impact.EThOS - Electronic Theses Online ServiceGBUnited Kingdo
