Dr Mithila Achintha is currently a University Lecturer in Structural Engineering at the University of Southampton.

My research focuses on computational, theoretical and experimental investigations on designing sustainable structures through innovative and efficient use of construction materials: concrete, Fibre Reinforced Polymer (FRP), and glass

Research Profile

I have over 14-year research track record in the field of novel and efficient use of glass, fibre reinforced polymer (FRP) and concrete in structural and facade engineering research and practice. I have established an internationally recognised research activity at Southampton University in the field of sustainable infrastructure materials and systems where I have been awarded and managed a total research funding/contracts approaching £490k, including funding from external sources (a total of ~£430k).

We have well established research collaborations with world-renowned UK and international research groups and a number of industry partners. My research group pioneered the field of modelling the effect of residual stress in commercially available construction sector glass by developing an experimentally validated finite element modelling technique (published in Exp Mech 2015). In the field of glass structures, we introduced the use of GFRP interlayers in anneal glass as a mean of enabling a ductile behaviour (published in Constr. Build. Mater. 2017). For the first time, we explored the potential use of FRP fabric as reinforcement in concrete beams (published in Mag. Concr. Res. 2017) as a mean of developing structurally efficient concrete structures.

Our research centred on the implications and challenges for structural engineering posed by the need for greater material and carbon efficiency in the built environment. Our current research interests aim to explore the use of sustainable infrastructure materials and systems and optimisation of structures.

Bogdan Balan completes PhD on ‘Analysis of Strength of Glass’

Bogdan Balan successfully defended his PhD thesis “Analysis of Strength of Glass”. The direct output of Bogdan’s PhD project is an experimentally validated finite element modelling technique that enables designers to incorporate the effect of residual stress in glass structural designs where the existing design guidelines unable to take into account for the residual stresses explicitly. Bogdan successfully modelled the residual stress distributions in float and tempered glass, and then stress evolutions in various key practical glass structural members under applied loads. In the second half of the thesis, Bogdan developed a novel form of glass–glass fibre reinforced polymer (GFRP) hybrids which are stronger and ductile compared to conventional laminated glass. The findings of Bogdan’s research will help industry to improve safety and economy glass structures.

Dr Mithila Achintha speaks at AGM of IStructE Southern Regional Group

Dr Achintha delivered a talk at the AGM of the Southern Regional Group of the Institution of Structural Engineers (IStructE) on 14th November 2016. Dr Achintha’s talk entitled “Recent Advances in Structural Glass Research” where he presented examples of novel forms of strong and ductile glass structural members and advanced numerical methods that can be used for design of complex glass structures.

Bogdan Balan’s work presented at CGC5

PhD student Bogdan Balan’s work on “Experimental and numerical investigation of float glass–GFRP hybrid beams” was presented at the Challenging Glass Conference 5 held in Ghent, Belgium.

Dr Mithila Achintha joins IStructE Façade Engineering and the Structural Use of Glass Study Group

Dr Achintha joined the “Façade Engineering and the Structural Use of Glass Study Group” of the Institution of Structural Engineering (IStructE). The Study Group aims to disseminate and advance knowledge in façade engineering and structural glass by bringing together consulting engineers, architects, contractors, manufacturers and researchers. Currently, Dr Achintha is a part of the Steering Group and an author of a forthcoming publication “Structural aspects of cladding”.

Book chapter on “Sustainability of glass in construction” published

A book chapter “Sustainability of glass in construction”, authored by Dr Achintha, is available in a new text book “Sustainability of construction materials ”, published by Woodhead Publishing. The chapter starts with a general introduction to applications of float glass as a building construction material, followed by a description of physical, optical, chemical and thermal properties of glass. Features and benefits of using glass in buildings, such as daylighting, solar control, low emissivity, thermal insulation, noise/vibration control, self-cleaning and fire resistance are discussed in details. The sustainability of glass as a construction material, and recycling and reuse of glass are also discussed. Discussion on structural glass design, technical guidelines and recommendations for structural glazing and joints are also presented. The chapter concludes with a section on future trends. Further details can be found on the Elsevier website .

Invited research seminar at the University of Oxford

Dr Achintha delivered an invited research seminar at the Department of Engineering Science, University of Oxford on 6th June 2016. His talk was entitled “Structural Glass: From Brittle Glass to Ductile Glass–GFRP Hybrids”. For more information on the Abstract of the talk visit the University of Oxford website.

Research collaboration with SIMTech and A*STAR (Singapore)

Dr Achintha has secured funding from the Agency for Science, Technology and Research (A*STAR), Singapore for a fundamental research project on load-bearing glass-adhesive joints. The research project is conducted in collaboration with Singapore Institute of Manufacturing (SIMTech).

Dr Mithila Achintha elected to HEA Fellowship

Dr Achintha was recently elected to Fellowship at the Higher Education Academy (HEA) . HEA is a British professional institution promoting excellence in higher education. HEA Fellowship is an international recognition of a commitment to professionalism in teaching and learning in higher education and demonstrates that practice of a Fellow is aligned with the UK Professional Standards Framework .

Research award from the Institution of Structural Engineers

Dr Achintha has recently secured Institution of Structural Engineers (IStructE) Research Award , which is the largest grant IStructE makes through the institution’s Research Fund. This funding was used to demonstrate the efficacy of thin, prefabricated glass fibre reinforced polymer (GFRP) laminates to prestress glass panels, and thereby to enable the development of strong and ductile glass structures using commercially available annealed glass. The grant was award based on the high quality of the research and its fulfilment of the industry focussed research challenge themes of the IStructE.

Dr Achintha appointed to steering committee of Composites UK Construction Sector Group

Dr Mithila Achintha was appointed to the steering committee of the Construction Sector Group (CSG) of Composites UK . As a steering committee member, he aims to facilitate a forum for discussion of common issues of working with fibre-reinforced polymer composites (FRPs) in construction industry and to find solutions to current difficulties, as well as outward facing dissemination of best practice. CSG also oversees the completion and publication of the FRP Bridge Design Guide.

Research award from Institution of Civil Engineers

Dr Achintha has recently secured the Institution of Civil Engineers (ICE) Research and Development Enabling Fund Award for the research proposal entitled “Intelligent Structural Forms for Concrete Structures”. The funding was used to support the experimental works of a recently completed PhD project and a MSc research project . The projects experimentally investigated the load response and the failure behaviour of rectangular prismatic concrete beams reinforced with an innovative and efficient combined flexural and shear reinforcement system made from carbon fibre reinforced polymer (CFRP) fabric. It is anticipated that the findings of this research could be effectively used in other applications such as non-prismatic concrete geometries and as permanent formwork/reinforcement in thin concrete members where the flexible characteristics of dry CFRP fabrics are most useful.
