Dear Colleagues,

The residual strength of reinforced concrete (RC) structures exposed to high and elevated temperatures due to fire is one of the main concerns of researchers in this field. Although valuable studies have been concentrated on this context, more efforts are still required since there has been a developing trend to present new concrete generations along with sustainable mixtures containing waste and recycled materials (aggregates and powders). Moreover, to improve the regulations and specifications of fire-resistant RC buildings containing new concrete generations, a detailed analysis of the material's resistance to high temperatures should be performed either in the laboratory or with advanced software. Also, analyzing damaged concrete structures and finding a practical and efficient way to improve the performance of the damaged structure are the other concerns of researchers in this field.

Accordingly, this Special Issue (SI) of “Buildings” intends to publish experimental and numerical studies on RC members with thermally-damaged concrete considering new concrete generations. The main objectives of the present SI are design criteria, fire tests, damage analysis, and repair. Submissions in the fields of both experimental and numerical studies are welcome. The addressed areas of research include, but are not limited to:

• Studying the effect of concrete composition on the structural performance of RC structures exposed to high temperatures.
• Determine the effect of nanomaterials (within concrete mixtures or used as coating agents) on improving the residual strength of concrete.
• Investigate the effect of new aggregates (industrial or recycled waste aggregates) on affecting the thermal expansion of hardened concrete.
• Numerically study the effect of high temperatures on large-scale RC members and multistory buildings.
• Finding efficient materials to repair thermally damaged concrete.
• Using different non-destructive techniques (NDT) to determine the internal damage to RC members exposed to fire.
• Presenting practical approaches for fire safety design of RC structures.

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.
