Seismic vulnerability assessment of reinforced concrete bridge piers with corroded bars

Dario De Domenico et al.

Summary: Reinforced concrete structures in aggressive environments, like bridge piers near the sea experiencing chloride attacks, may have increased seismic vulnerability. A phenomenological model is developed to describe the seismic behavior of corroded RC elements, taking into account the mechanical degradation of concrete and steel caused by corrosion. The model is validated and then used for the seismic vulnerability assessment of a specific bridge in Italy, where the RC bridge piers are exposed to carbonation and chloride-induced corrosion. The proposed approach is computationally efficient and applicable to other existing RC bridges in corrosive environments.

Damages and Failures of Structures in Izmir (Turkey) during the October 30, 2020 Aegean Sea Earthquake

Tuba Gurbuz et al.

Summary: This study conducted a site investigation in the earthquake-hit area of Izmir, Turkey, after the Aegean Sea earthquake. The investigation found that the earthquake caused severe damages to buildings, including collapses and heavy damage. The paper discusses the seismic vulnerabilities of structures and presents recommendations for preventing such failures. Additionally, the study also investigated non-structural damages and outlined seismological aspects and characteristics of the recorded strong ground motion.

Seismic vulnerability assessment of reinforced concrete bridge piers with corroded bars

Dario De Domenico et al.

Summary: In this study, an easy-to-use phenomenological model is developed to describe the seismic behavior of corroded reinforced concrete (RC) elements. By validating the model through experimental tests and conducting numerical analyses, the seismic vulnerability of RC bridges in corrosive environments is assessed.

Concentrated plasticity modelling of RC frames in time-history analyses

Eleonora Bruschi et al.

Summary: This study examines the impact of modeling decisions in concentrated plasticity formulations on the behavior of reinforced concrete frames in time history analyses. By investigating the sensitivity of estimated structural response on certain assumptions, it compares the results between different formulations and highlights the differences in predictions, particularly regarding inter-story drift ratio and maximum base moment. Ultimately, it suggests that improving the agreement between concentrated and distributed plasticity formulations may be achieved through adopting an effective area moment of inertia dependent on axial load.
