Capacity Assessment of Corroded Reinforced Concrete Structures

Dear Colleagues,

It is widely accepted that the occurrence of corrosive phenomena on steel reinforcement is closely linked to the degradation of structural integrity and durability of Reinforced Concrete (RC) buildings. However, the assessment of structural capacity of corroded RC elements consists of a complex task in the engineering field, since it depends on several variable factors, such as the chloride or CO₂ concentration, the temperature and humidity conditions, the porosity and mixture of concrete, the chemical composition of steel reinforcement, the type of corrosion (uniform of pitting), the residual cross-section of corroded rebars, the respective seismic building regulations of different countries, etc.

Taking into account the negative consequences of corrosion on the durability of RC structures, as well as the high financial costs for rehabilitation and repair of the aged structures, the need to enhance the existing design codes considering the corrosive factor is raised. In this context, this Special Issue of Buildings aims to strengthen the scientific progress that has already been achieved both by adding evidence upon the assessment of the mechanical behavior of corroded steel reinforcement, the degradation of concrete durability, the loss of steel–concrete bonds and on the other hand, by proposing methods of dealing with the structural degradation and proposals for the restoration of strengthening of damaged structural elements.

Topics to be covered in this Special Issue include:

• Monitoring of corrosion level via surface concrete cracking;
• Measurement of critical chloride concentration, in the laboratory and on site;
• Assessment of corroded RC structures;
• Modelling the corrosive factor in RC elements;
• Coatings to enhance durability of structures exposed to chloride-induced corrosion;
• Bond-slip degradation due to corrosion;
• Case studies and applications.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Buildings is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
