<span>Reinforced concrete</span> dapped‐end beams for existing bridges: Reliability of finite element models Open
Half‐joints in reinforced concrete girder bridges are generally considered critical elements, susceptible to degradation and potentially impacting the overall structural behavior. An Italian project carried out by ReLUIS interuniversity co…

Experimental Behaviour of Tensioner for Rigid Hangers of Arch Bridges Open
In steel tied arch bridges where the hangers are made of rigid bars, the replacement of damaged hangers is rather complex. In fact, while generally the cable hangers are already prepared with anchors at the ends and their replacement trace…

Seismic Retrofit of Concrete Buildings Damaged by Corrosion: A Case Study in Southern Italy Open
A case study of a building in southern Italy, subjected to high degradation by corrosion and waiting to be assessed for retrofit interventions, is presented. The owner required modifications to the building configuration, including a new l…

Seismic Vulnerability of Segmental Bridges with Drop-In Span by Pushover Analysis Open
Insight into the application of pushover analysis to prestressed concrete segmental bridges built in the 1950s–1970s by cantilevering with medium-large span length is provided. Seismic assessment must be carried out considering the whole s…

Experimental Investigation on Innovative Stress Sensors for Existing Masonry Structures Monitoring Open
Historical masonry structures often suffer gradual deterioration that in many cases can compromise the safety levels and the operating conditions of the buildings. In this context, Structural Health Monitoring (SHM) is an effective tool fo…

Monitoring of stress distribution in damaged small-scale masonry walls by using two innovative sensors Open
Structural Health Monitoring (SHM) represents a strategic solution for the preservation of cultural heritage buildings. Existing masonry structures often suffer reductions in mechanical performances due to physiological aging of material c…

Assessment and strengthening of reinforced concrete bridges with half‐joint deterioration Open
Existing Niagara‐type concrete cantilever bridges, which in Italy are called Gerber bridges, suffer from degradation due to reinforcement corrosion and a consequent reduced load‐bearing capacity. The assessment of these structures is there…

Effects of corrosion on a steel bowstring bridge in marine environment: A case-study of assessment and retrofit Open
The case-study of a steel bowstring bridge set in a marine environment and highly damaged by corrosion is presented. The bridge was built in 2004 and was repainted for corrosion protection in 2010. Despite the recent construction and the m…

Steel and composite tied-arch bridges: a conceptual approach to structural design Open
The behaviour of tied-arch bridges with composite decks (bowstring bridges) is overly sensitive to the different choices made by the designer in the first phases of the conceptual approach, mainly in the design of the arch and the deck. Th…
