Research Centre for Civil Engineering Structures

This centre brings together three interlocking groups, all focusing on the analysis of different complex and/or special engineering structures: long-span bridges; tall buildings; and nuclear structures.

'Complex' or 'special' structures are primarily all those that fall outside the scope of current structural design codes of practice. Particularly challenging problems arise when these structures are situated in adverse environments, resulting occasionally in extreme loads to structures (strong wind fronts/ hurricanes, floods, (rogue) sea waves, earthquakes, fire/blast, corrosion, climate change, extreme temperature and humidity). A major challenge for designers is to analyse such complex structures, especially when high performance objectives are set for multiple levels of design actions. Designers have to exercise their best judgement in selecting those methods that can be applied to real-life (as opposed to academic) structures and can produce a reasonable design solution that would lead to high-performance structures without being over-conservative.

The structures forming the focus of the centre present similar challenges that can be addressed in a fairly unified way; existing expertise and infrastructure at City are utilised to give a well-rounded response to problems such as performance-based structural design, use of high-performance materials, and structural monitoring.

Smart Structures and Structural Health Monitoring (SSSHM)

"The choices that we make about infrastructure enable us to shape the type of economy and society that we want for the future. Infrastructure has the capacity to unlock economic potential in individual regions and ensure that growth and opportunities are distributed across the country…"

(UK National Infrastructure Plan 2014, HM Treasury)

A well-identified Grand Challenge in Civil/Structural Engineering is to enhance the resiliency of contemporary engineering structures and infrastructure networks exposed to natural and man-made hazards and to improve sustainability in construction, operation, and decommissioning of structured facilities. Through both fundamental and experimental research, the SSSHM unit pioneers cost-effective solutions to monitor civil engineering structures using wireless sensor networks for design validation, condition assessment, and damage detection. Special attention is focused on sparse data acquisition and processing techniques and on the development and field deployment of innovative fibre optic-based sensors. Further, the SSSHM unit develops innovative passive adaptive and semi-active devices for vibration control and/or energy harvesting in tall buildings and long-span bridges exposed to dynamic loads within a multi-objective performance-based design framework in multi-hazard environments. The unit is committed to world-leading analytical/mathematical, computational, and experimental research to deliver paradigms of 'smart' engineering structures that can sense, react, and adapt to their environment to ensure fit of purpose, users' comfort and minimal environmental impact.

Earthquake Engineering and Seismic Risk Management (EESRM)

"Earthquake engineering is to the rest of the engineering disciplines what psychiatry is to other branches of medicine: It is a study of pathological cases to gain insight into the mental structure of normal human beings.
This aspect of earthquake engineering makes it challenging and fascinating, and gives it an educational value beyond its immediate objectives".

N.M. Newmark and E. Rosenblueth (Fundamentals of earthquake engineering, 1971)

The EESRM Research Unit focuses on the seismic performance of complex or irregular buildings, bridges and other civil engineering structures. The methods used are both experimental (utilising the new facilities of the Structures Laboratory at City) and analytical, using a number of sophisticated nonlinear finite element analysis programs, some of which (ATENA, IDARC) have been substantially enhanced by researchers of the Centre and their co-workers. The Unit also addresses several aspects of Seismic Risk Management, such as prediction of future losses and development of earthquake scenarios, and pre- and post-earthquake assessment techniques for damage structures (buildings, bridges).

Members: Professor Andreas J. Kappos (coordinator), Dr Agathoklis Giaralis, Professor Ashraf Ayoub, Dr Panagiotis Mergos, Dr Alfredo Camara, Professor Tong Sun, Professor Nick Karcanias, Professor George Halikias

Advanced Materials for Civil Engineering Structures

"Inventing is a combination of brains and materials. The more brains you use, the less material you need."

Charles Kettering (1876-1958, holder of 186 patents)

The past two decades witnessed the development of several new materials for infrastructure construction. These include fibre-reinforced concrete using steel or polymeric fibres; the so-called Engineering Cementitious Composites (ECC); reactive powder concrete; nano-reinforced concrete using carbon nano tubes or nano fibres; high-strength reinforcement; shape memory alloys; fibre-reinforced polymers and fibre-reinforced cementitious matrix composites; textile reinforced mortar among others. The overall behaviour of these materials has not been fully explored. In this unit, research will use experimental and analytical techniques to evaluate the constitutive behaviour of these materials under combined mechanical and thermal loading, as well as the structural behaviour under natural and man-made hazards.

Members: Professor Ashraf Ayoub (coordinator), Professor Ranjan Banerjee, Dr Brett McKinley, Dr Tatyana Micic, Dr Feng Fu, Dr Alfredo Camara
