“…These aesthetically pleasing, strong, minimum maintenance bridges have withstood the test of time and have contributed greatly to Rapid construction of arch bridges using the innovative FlexiArch Long, Kirkpatrick, Gupta, Nanukuttan and Mc Polin our present infrastructure. Considerable development of the system has taken place since the original paper by Long et al (2008), but the full potential for application to short/medium span bridges has yet to be realised.…”

Masonry arches are strong, durable, aesthetically pleasing and largely maintenance free, yet since 1900 there has been a dramatic decline in their use. However, designers, contractors and clients now have access to a new method of constructing arches incorporating precast concrete voussoirs interconnected via polymeric reinforcement and a concrete screed. No centring is necessary, as the FlexiArch, when it is lifted, transforms under the forces of gravity into the desired arch shape. After discussing general aspects of innovation, the basic concept of the arch bridge system is presented along with technological advances since it was patented. Experiences gained from building over 40 FlexiArch bridges in the UK and Ireland and from model and full-scale tests carried out to validate the system during installation and in service are described. Thus under load the system behaves like a traditional masonry arch and existing analysis methods can be used for design and assessment.

Ageing is an inherent feature of nature. Yet it seems to be a rather new topic in both science and engineering. The main reason for increasing attention for ageing as a topic is the growing awareness that, particularly in industrialized countries, ageing of our assets is a financial burden for the society and affects the overall sustainability of our planet. In this contribution, the urgency and challenges of ageing of concrete structures are addressed. The complexity of ageing problems will be illustrated by looking in more detail to the evolution in concrete mix design and the consequences thereof for the long-term performance of concrete structures. Emphasis will be on ageing of concrete infrastructure and justification of research on ageing phenomena. Keywords: infrastructure; sustainability; ageing; mix design; autogenous shrinkage; codes.

Sin embargo, parece ser un tema bastante nuevo en la ciencia y la ingeniería. La principal razón para aumentar la atención por el envejecimiento como tema es la creciente conciencia de que, en particular en los países industrializados, el envejecimiento de nuestros activos es una carga financiera para la sociedad y afecta la sostenibilidad global de nuestro planeta. En esta contribución se abordan la urgencia y los desafíos del envejecimiento de las estructuras de concreto. La complejidad de los problemas de envejecimiento se ilustra examinando con más detalle la evolución del diseño de la mezcla de concreto y sus consecuencias para el rendimiento a largo plazo de las estructuras de concreto. Se hace hincapié en el envejecimiento de las infraestructuras de concreto y en la justificación de la investigación sobre fenómenos ...

“…4.6. 'Flexiarch' as a sustainable form of construction for small to medium span bridges Due to long service lives exhibited by masonry arch bridges (thousands of years as opposed to several decades for reinforced and pre-stressed concrete bridges), a novel flexible concrete arch system was developed at Queen's University Belfast [18]. This system has the potential to be highly sustainable due to the low or zero amount of steel reinforcement.…”

h i g h l i g h t sSignificant research synergy exists between UK and China in the field of sustainable solutions for the built environment. Considerable opportunity exists to deploy UK-based knowledge to leading Chinese universities and research institutions. Proof-of-concept studies in China confirmed the applicability of UK-based tests for structural durability assessment. The reported work is aimed at enhancing the structural health performance of concrete bridges in marine environments. The international collaborative programme described is of interest and benefit to other organisations active in this field.
