This paper provides a discussion and thoughtful application on large sample of the procedures for classification existing bridges recently adopted in Italy defined within Italian Guidelines classification, risk management, safety evaluation monitoring early published Operating Instructions. Focusing at territorial level, first logic flows to base structural are shown, resulting definition “structural warning class”, providing motivations that support criteria such procedures. Then,...
Rack supported warehouses (RSWs) are structures that, as currently designed, were proved to be characterized by very limited sources of ductility and prone quasi brittle failures that mainly involve key components diagonal-to-upright base connections. Therefore, in high seismicity areas they often protected with seismic isolation, which is surely effective but greatly complicates the execution phase. As an alternative path, a dedicated design approach presented this paper, exploiting...
This study presents a methodology for deriving probabilistic model estimating the braking force that is, on contrary, traditionally based deterministic approaches in bridge design codes. The stochastic resorts to Weight-In-Motion (WIM) dataset collected from provincial road observing real traffic load distributions terms of vehicle gross weight and length, inter-vehicle distance. Using Monte Carlo simulations, convoys are generated calculating resultant force, by assuming deceleration...
The present work aims to provide an in-situ inspection methodology for prestressed concrete bridges with post-tensioned cables (PT bridges). adoption of non-destructive techniques (NDT), already widely employed in other engineering fields, is proposed, providing reliable information a relatively low impact on the existing infrastructure. For each specific topics (i.e. cables' layout detection, defect localization and quantification, estimation residual prestressing force) proposed...

This is Part 2 a more extensive publication dealing with results such presents experimental measurements analyses in order to determine motion subjected actions produced by two largest six bells. numerical...
Abstract A refined component model is proposed to predict the inelastic monotonic response of exterior and interior beam‐to‐column joints for partial‐strength composite steel–concrete moment‐resisting frames. The joint typology designed exhibit ductile seismic through plastic deformation developing simultaneously in column web panel shear, bolted end‐plate connection, flanges bending steel reinforcing bars tension. can handle large deformations consistent with high ductility Slip between...
The Emilia, May-July 2012, earthquake has dramatically highlighted the only hazards facing people in insufficiently secured workplaces, but also socio-economic consequences of interruption production activities. After event, order to guarantee suitable safety levels, Italian government asked for a generalized seismic retrofit buildingsaffected by under consideration. Considering that Emilia is one most industrialized region, number industrial buildings be verified could however lead not...
A 142-m, three-span continuous footbridge over the Esino River (Italy) is considered as a case study to illustrate number of challenging aspects in its static and dynamic design. The adoption an optimized steel deck with variable cross section together use external prestressing tendons central span allows substantial reduction structural weights. resulting requires proper model for assessment behavior up ultimate limit state well attention vibration control under pedestrian loading at...
Abstract This paper presents the results of a multi‐level pseudo‐dynamic seismic test program that was performed to assess performance full‐scale three‐bay, two‐storey steel–concrete composite moment‐resisting frame built with partially encased columns and partial‐strength beam‐to‐column joints. The system designed develop ductile response in joint components joints including flexural yielding beam end plates shear column web panel zone. ground motion producing damageability limit state...
Abstract In the last few years, construction of new high-speed (HS) railways across Europe, as well in many other countries, has required different bridges and viaducts. Together with classical concrete solutions, steel–concrete composite typologies have been developed, giving light cheap structures. Despite these studies applications, some concerns still remain about definition reliable models for evaluation their actual dynamical behaviour under HS train passage. particular, influence...
