A framework for robustness assessment in the context of corroded RC structures

Structural robustness is an emergent concept related to the structural response to damage. At the present time, robustness is not well defined and much controversy still remains around this subject. Even if robustness has seen growing interest as a consequence of catastrophic consequences due to extreme events, the fact is that the concept can also be very useful when considered on more probable exposure scenar...

A reliability-based measure of robustness for concrete structures subjected to ...

This work is a contribution to the definition and assessment of structural robustness. Special emphasis is given to reliability of reinforced concrete structures under corrosion of longitudinal reinforcement. On this communication several authors’ proposals in order to define and measure structural robustness are analyzed and discussed. The probabilistic based robustness index is defined, considering the reliab...

Robustness analysis of deteriorating reinforced concrete slabs

Corrosion of reinforcement bars in concrete structures is the most significant deterioration mechanism in these structures. Corrosion is extremely difficult to predict and, consequently, can be regarded as an unpredictable event. Following this, robustness assessment methods can be employed to define the susceptibility of a structure to corrosion. In this work, robustness is measured in terms of the remaining s...

Robustness of corroded reinforced concrete structures. A structural performance...

Structure and Infrastructure Engineering, 1-17 ; The aim of this work is to provide new contributions in order to define more accurately the structural robustness concept, particularly when applied to corroded reinforced concrete (RC) structures. To fulfill such task, several robustness indicators are analyzed and discussed with special emphasis on structural performance based measures. A new robustness defini...

Robustness of corroded reinforced concrete structures

Short Term Scienti c Mission, COST ACTION TU-0601 ; The deterioration of existing structures has been a growing concern in the last decade. Signi cant attention has been paid to the deterioration of bridges, since signi cant costs in repair and replacement are expected in the next decades. At the same time structural robustness seems to be an emergent concept related to the structural response to damage. At th...
