91, Aglantzias Ave.
Dr Nicolas Hadjipantelis is Lecturer in Structural Engineering at the Department of Civil and Environmental Engineering at the University of Cyprus, where he is conducting research in the area of Steel Structures and is teaching courses related to steel structures and structural stability at both undergraduate and postgraduate level.
 
Dr Hadjipantelis is the founder and leader of the Steel Structures Laboratory at the University of Cyprus, which comprises a state-of-the-art Wire Arc Additive Manufacturing (WAAM) system. Dr Hadjipantelis has several years of experience in the research area of WAAM, specifically in the production, testing, modelling, and development of design rules for WAAM structures.
 
Before joining the University of Cyprus in August 2020, Dr Hadjipantelis has worked for two years as a Research Associate at Imperial College London in affiliation with The Alan Turing Institute, which is the United Kingdom's national institute for data science and artificial intelligence.
 
Dr Hadjipantelis holds a PhD in Steel Structures from Imperial College London, for which he was awarded an Imperial College President’s Scholarship. As part of his undergraduate studies at the University of Bristol, where he obtained a first class honours MEng degree in Civil Engineering, he studied and conducted research for an academic year at the University of California, Berkeley.
 
Dr Hadjipantelis is an Associate Member of the American Society of Civil Engineers (ASCE), a Graduate Member of the Institution of Structural Engineers (IStructE), a Full Member of the Cyprus Scientific and Technical Chamber (ETEK), a Full Member of the Cyprus Association of Civil Engineers (CYACE).

Research philosophy
 
My research philosophy is based on three pillars: Innovation, Quality and Impact.
Innovation fosters novel and create ideas, which quality work transforms into recognised research excellence, which has a positive impact on the wider society, the physical environment and the built environment.
 
Research areas
 
My research activity lies in the field of steel structures and includes the following research areas:
 
(1) Metal 3D printing – Wire Arc Additive Manufacturing (WAAM)
(2) Prestressed steel structures
(3) Cold-formed steel structures
(4) Hot-rolled steel structures
(5) Structural stability
 
Methodologies
 
(1) Experimentation – e.g. full-scale, member and material testing
(2) Numerical modelling – e.g. finite element modelling (GMNIA)
(3) Analytical modelling – e.g. energy methods and structural mechanics
 
Research output
 
My research output is published in high-impact peer-reviewed journals, including the Journal of Structural Engineering (ASCE), Engineering Structures, Thin-Walled Structures and the Journal of Constructional Steel Research, and is presented at key international conferences.
 
Wire Arc Additive Manufacturing
 
Dr Hadjipantelis has recently set up a Wire Arc Additive Manufacturing (WAAM) facility in the Steel Structures Laboratory of the University of Cyprus.
WAAM is a metal 3D printing technique that employs a robotic arm in conjunction with a welding machine to print metallic components of any desired geometry and size in a layer upon layer fashion, as shown below. The facility is used to produce specimens that are tested in the laboratory with the aim of demonstrating the benefits of using WAAM in construction.
 
You can watch a presentation by Dr Hadjipantelis outlining the use of WAAM in construction in this video (in Greek).
 
WAAM UCY
 
Dr Hadjipantelis has actively participated in the final full-scale loading tests on the MX3D Bridge, the first metal 3D printed pedestrian bridge in the world.

Prestressed steel structures
 
Dr Hadjipantelis is conducting research work in the area of prestressed steel structures. Dr Hadjipantelis has proposed a novel concept, whereby the load-carrying capacity and serviceability performance of cold-formed steel beams are enhanced by utilising prestressing techniques. The prestressing force is applied by means of a high-strength steel cable, which induces initial stresses in the beam that are opposite in sign to those introduced during the subsequent loading stage.
 
Prestressed CFS beams
 
In a recent study, Dr Hadjipantelis has also examined the use of externally anchored prestressed cables to enhance the stability of steel truss compression elements.
