Dr Konstantinos Skalomenos is Lecturer of Structural Engineering. His research is mainly directed towards cognizing the structural response under earthquakes, controlling the structural vibration and damage, and coping with large-scale disasters.

Dr. Skalomenos has expertise in conducting both analytical and experimental research. He is seasoned to determine the demand as well as to quantify the structural capacity. A good balance between both aspects is what he would like to pursue in his academic life.

His specialization is on steel and composite steel/concrete structures. Currently, he conducts research on advanced computational modelling for collapse analysis and effective experimentation of structures; conceptual development of resilient structural technologies adopting cutting-edge materials and manufacturing methods; design and implementation of low-disruption retrofitting schemes for aging infrastructure upgrades.

Biography

Dr. Konstantinos Skalomenos graduated from the Department of Civil Engineering of the University of Patras, Greece, in 2007. He received his M.Sc. in 2009 and Ph.D. in 2014 from the same University. As part of his Ph.D. thesis, he conducted analytical research on the seismic performance and design of concrete-filled steel tubular columns/moment resisting frames (CFT-MRFs). After his Ph.D. studies, he moved to Japan in 2015 as international post-doctoral research fellow of Kyoto University awarded by the Japan Society for the Promotion of Science (日本学術振興会 JSPS). In 2017, he was appointed as Specially Apptd. Assistant Professor of the Disaster Prevention Research Institute (DPRI), Kyoto University, where he studied the ultimate failures of steel and composite structures as experimentalist. He joined the University of Birmingham as Lecturer in 2019.

Dr. Skalomenos' research has been funded from the Grants-in-Aid for Scientific Research of JSPS fellowships, Collaborative Research Programs and New Exploratory Research Grants of DPRI, the Japan-ASEAN Science, Technology and Innovation Platform (JASTIP-Network) as well as from Industrial Partners of Kyoto University, such as the Neturen Co. Ltd and Nippon Steel & Sumitomo Metal Co. Ltd.

Dr. Skalomenos' professional experience includes roles as Construction Quality Engineer in the infrastructure management and construction company of Hellenic Telecommunications Organization (O.T.E Estate S.A.) in 2008-2011, and in the Engineering Directorate of the Hellenic Army Supreme Military Support Command in 2012. In 2013-2015 he worked as Structural Engineer in a University-led project for the assessment and retrofitting of old r/c office building structures.

Over the last few years, Dr Skalomenos has worked on the organization of international workshops with colleagues from EU and UK Universities and disaster prevention research institutes of Greece, China and Japan. He has also served for 1½ years in the administrative council of the Greek Society of Civil Engineers, and for 5 years in national representative bodies of the Technical Chamber of Greece (TCG) with roles related to promoting science and technology in the civil engineering profession and education.

Teaching

Dr Skalomenos has taught a variety of Civil and Structural Engineering modules at undergraduate and postgraduate levels.

Postgraduate supervision

Currently, Dr Skalomenos is mentoring Ph.D. and Master students. Their research is related to:

  • Ultimate behavior of new-type cold-formed steel hollow section columns
  • Multi-state damage retrofit of steel and composite structures and reliability assessment

He is interested in supervising postgraduate students in the research fields of structural engineering and structural dynamics emphasizing on infrastructure resilience, structural and material efficiency, and implementation.

Research

Towards a novel structural design where the fundamental knowledge of structural mechanics will balance the inherent benefits of material properties.

Current research activities

Dealing with buckling failures

Steel sections are susceptible to local buckling while steel members often buckle globally under large compression stresses. A large variety of new construction steels ranged from low-yield point steels (fy=100~200MPa) up to ultra-high-strength steels (fy=700~1000MPa) as well as the use of concrete as a buckling-restrained material are introduced together with efficient member configurations to strengthen steel structures stability and improve performance.

Connections failure modes

An advantage of steel and composite structures is their quick assembly at predefined connection locations. However, connections often fail prematurely triggering significant structural instabilities, and finally, overall collapse of structures. The present project conducts experimental research to quantify the actual capacity and failure modes of gusset plate connections in steel braced frames and develops new ductility-based design methodologies within the framework of Eurocodes and AISC codes.

Reliable and robust design methods

The robust design of structures is a fundamental step to reach resiliency. This research develops a new design method on the basis of analytical and experimental response databases. Optimum empirical equations and design flowcharts are developed to directly link the targeted local deformations of members, hence damage, with the desired overall structural response and code-based design forces.

Retrofitting of building structures

Existing old structures and infrastructures is the Achilles’ heel of our built world. These types of structures should be treated very carefully to bring them up to current safety standards with low cost and minimum disturbance. This project implements steel and composite materials as the basis for developing lightweight and ductile retrofitting technologies for both the super-structure and foundation.

Research Advanced Tools

Hybrid analysis/test platform

Testing individual components of a structure separately in the Lab ignores their actual interaction and loads transfer. To explore actual behavior the present research develops a hybrid analysis/test platform that combines advanced finite element simulations with a multi-axial actuator loading system. The system updates both the loads and deformations to the test substructure interactively with the remain analytical substructure (online test).

City disaster simulator

Nowadays cities tend to be more vulnerable to natural hazards. The present research is conducted in collaboration with the Institute of Engineering Mechanics (IEM) - Earthquake Administration of China. A simulation platform, named YouSimulator, is introduced to model, assess and visualize the performance of urban areas and cities against fire and earthquake disasters based on multiple data resources and modern scalable analysis techniques.
