Dear colleague,

We would like to inform you about the First International Conference on Durability, Repair and Maintenance of Structures, which will take place at the Faculty of Engineering of the University of Porto (FEUP) in Porto, Portugal, on the 16th and 17th of March 2023 ( This conference will be chaired by Professor Lucas F. M. da Silva (University of Porto, Portugal) and co-chaired by Professor Kenneth Reifsnider (University of Texas at Arlington, USA), Professor António Torres Marques (University of Porto, Portugal) and Professor Masayuki Nakada (Kanazawa Institute of Technology, Japan).

The focus of this conference is the study of the durability, repair and maintenance processes of engineering structures. Novel research works carried out in various topics within these wider themes will be accepted.

Among the topics covered are:


DURACOSYS Conference has been created by Professors Albert Cardon (Free University of Brussels, Belgium), Ken Reifsneider (USA) and Hiroshi Fukuda (Tokyo University of Science, Japan). After the meeting on Durability Analysis of Polymer Based Composite Systems (August 1990, Brussels, Belgium) and the Invited International Informal Seminar on Durability Analysis of Composite Systems (July 1993, Porto, Portugal), the following International Conferences took place:

DURACOSYS 2008 - 8th International Conference on Durability of Composite Systems, held at Faculdade de Engenharia da Universidade do Porto, Portugal, July 16th – 18th 2008, took place after the death of Prof. Albert Cardon, and paid a Tribute to him during the Conference. In fact, besides being a co-founder of these Conferences, Prof. Cardon has devoted his life to Durability of Composite Systems and, above all, became an exemplary professor.

Then, the following sequence occurred:

Some time has passed and it was felt a need to enlarge the scope of the conference although keeping the focus on durability, but including repair and maintenance processes of engineering structures – DRMS 2023 - Durability, Repair and Maintenance of Structures.
