This paper presents the development and analysis of a bridge bearing database consistent with 2020 Italian Guidelines (LG2020), currently enforced by law for risk classification management existing bridges. The was developed putting together contribution 24 research teams from 18 universities in framework project foreseen agreement between High Council Public Works (CSLP, part Ministry Transportation) consortium ReLUIS (Network Earthquake Structural Engineering University Laboratories)....
The upgrading of bridges located in seismic areas and built according to obsolete codes is becoming a priority task for highway administrations. Among the possible strategies, use fiber-reinforced plastic (FRP) jackets gaining widespread acceptance. In this paper, design equation proposed determine optimal thickness FRP jackets, enhance ductility existing reinforced-concrete (RC) bridge piers with circular cross sections. procedure stems from definition an index, given as ratio target...
Lattice discrete particle models (LDPM) effectively relate concrete heterogeneity in terms of coarse aggregate–paste structure to damage patterns and load-displacement response. Interest this type model is enhanced by its ability overcome issues that plague traditional methods, such as mesh dependence need for energy regularization. Herein, an experimental procedure developed identify the mechanical parameters defined at mesoscale. The bounding surface LDPM modified accept mesoscale inputs....
In this paper, a new intensity measure of earthquakes for probabilistic seismic analysis is presented skewed highway bridges. Three different cases bridges with skew angles (<TEX>$0^{\circ}$</TEX>, <TEX>$30^{\circ}$</TEX> and <TEX>$45^{\circ}$</TEX>) are considered. Well-known measures (e.g., PGA, <TEX>$S_a$</TEX>) evaluated critically discussed based on sensitivity analysis: efficiency, practically, proficiency sufficiency considered in detail. The analyses demonstrated that the have to...
Versatility and high performance in terms of specific stiffness strength, as well non-corrosive sensitivity, make FRP (Fiber-Reinforced Polymer) cables a viable alternative to steel ones the development prestressing systems. On other hand, orthotropic brittle nature FRPs could trigger premature failure cable anchorage system, for which several solutions have been proposed so far civil structural applications. In this context, after preliminary state art, work introduces split wedge (ϕ = 12...
In this study, we try to compare different intensity measures for evaluating nonlinear response of bridge structure. This paper presents seismic analytic fragility a three-span concrete girder highway bridge. A complete detail modeling parameters and also its verification has been presented. Fragility function considers the relationship intensities ground motion probability exceeding certain state damage. Incremental dynamic analysis (IDA) subjected from medium strong motions. suite 20...
A simple probability-based method is presented for assessing the state of existing bridges under scenario earthquakes in order to define their current safety level and eventually decide need strengthening interventions. The based on probabilistic description bridge capacity, expressed terms input peak ground acceleration, fulfill a predefined performance level. All uncertain quantities influencing response are treated as random, so that also random. damage function introduced yields actual...
The experimental characterization of historical bell towers and wall belfries can provide important information for the calibration numerical models as well to implement proper restoration strategies. Within this framework, presented study is concerned with dynamic assessment an ancient belfry dating back 1537. structure part "Santa Maria in Aracoeli Church" (Rome, Italy), heritage construction placed on summit Capitoline Hill, close building that hosts Major's office.
