Ultrasound monitoring for evaluation of damage in reinforced concrete

Damage-Based Seismic Performance Evaluation of Reinforced Concrete Frames

A damage-based approach for the performance-based seismic assessment of reinforced concrete frame structures is proposed. A new methodology for structural damage assessment is developed that utilizes response information at the material level in each section fiber. The concept of the damage evolution is analyzed at the section level and the computed damage is calibrated with observed experiment...

Acoustic Emission for Monitoring Damage Ac- cumulation in Reinforced Concrete Structures

Acoustic emission (AE) analysis is a good tool for monitoring the formation of damage in a structure. A loading experiment with a reinforced concrete beam was carried out and the obtained AE data were analyzed in order to get information about the internal processes of deterioration. Events could be localized, and their estimated source coordinates coincide with the developing crack planes. The...

Damage Assessment of Reinforced Concrete Buildings Considering Irregularities (RESEARCH NOTE)

Structural damage can be controlled in performance based seismic design (PBSD) according to the requirement under a certain hazard level. During strong ground motion (GM) such buildings suffer minor to major damages depending on the shaking level of GM. The available damage assessment methods are complex, tedious and time-consuming procedure. In the present study, a simplified empirical model h...

Probabilistic assessment of the seismic damage in reinforced concrete buildings

The main objective of this article is to assess the expected seismic damage in reinforced concrete buildings from a probabilistic point of view by using Monte Carlo simulation. To do that, the seismic behavior of the building is studied by using random capacity obtained by considering the mechanical properties of the materials as random variables. Starting from the capacity curves, one can obta...
