Evaluación de la salud estructural de las pilas del puente peatonal de Nulti

Abstract

The research on the assessment of the structural health of the piles of the Nulti Pedestrian Bridge highlights their importance for the safety and stability of the structure. Various non-destructive tests, such as Topography, Ultrasonic Testing, Iron Scanner, Ambient Vibration, and Schmidt Hammer Testing, were conducted to detect possible damage.

The results revealed that the concrete structures, specifically the piles, exhibited displacements but were functional despite the time elapsed since their construction and the impact of a heavy-duty vehicle.

The SAP software was employed to model the piles with their current characteristics for a more detailed analysis. Analyses such as Modal-Spectral, Time-History, and Static Nonlinear Analysis (Pushover) were performed, enabling the assessment of the piles under maximum capacity, identification of possible future failures, and solutions proposal to strengthen their structural resistance.

In addition to the mentioned tests and analyses, visual inspections were conducted, and a preventive and corrective maintenance plan was developed to ensure that the piles remain functional in the long term.
