Sustainability has become an increasingly important component of requirements for the rehabilitation bridge structures. Responsible use our limited natural resources is essential future generations, so whole process must be taken into account, in terms structural integrity. The environmental impact these types structures major – demolition and reconsideration e.g. reinforced concrete structure ...

Population growth followed by the dramatic increase and demand for new services created an urgent and overwhelming need for infrastructures of civil engineering structures. However, the current infrastructure work using various techniques and conventional materials for construction will not solve the traditional and continuous deterioration of concrete structures due to corrosion of steel. One ...

Abstract The Kintaikyo Bridge, with its elegant wooden arches, has a unique pier shape and continues to be loved by residents visitors alike. Although this bridge is an active footbridge important landscape element along the Nishikigawa River river beach, rationality or irrationality of piers remains unknown. This paper intended clarify engineering characteristics for first time conducting 1/12...

Abstract Bridge construction is one of the cores traffic infrastructure construction. To better develop relevant bridge science, this paper introduces main research progress in China and abroad 2021 from 12 aspects. The content consists four parts first part about structure analysis theories, including concrete high-performance materials, steel bridges, composite girders cable-supported theorie...

Accepting the challenge of the future in the field of civil engineering smart structure applications, the province of Manitoba is undertaking the responsibility of constructing the first bridge in Canada totally prestressed and reinforced for shear by cru:bon fibre reinforced plastic (CFRP) reinforcement. Portion of the concrete deck slab is also reinforced exclusively by FRP reinforcements. Th...

A concise state-of-the-art survey of fiber-reinforced polymer ~also known as fiber-reinforced plastic! composites for construction applications in civil engineering is presented. The paper is organized into separate sections on structural shapes, bridge decks, internal reinforcements, externally bonded reinforcements, and standards and codes. Each section includes a historical review, the curre...

Cyclodextrin glycosyltransferase (CGTase) catalyzes the formation of cyclodextrins from starch. Among the CGTases with known three-dimensional structure, Thermoanaerobacterium thermosulfurigenes CGTase has the highest thermostability. By replacing amino acid residues in the B-domain of Bacillus circulans CGTase with those from T. thermosulfurigenes CGTase, we identified a B. circulans CGTase mu...

Cable-stayed bridges have emerged as the dominant structural system for long span bridge crossings during the past thirty years. That success is due to a combination of technical advancements and pleasing aesthetics attributes. The interaction of the various structural components results in an efficient structure which is continuously evolving and providing new methods to increase span lengths....

The development of systems practitioners in engineering has revealed the need to bridge between the research methods teaching of engineering management and soft systems approaches. Whilst action research might be viewed implicitly as the research strategy of systems practice we argue that engineering management research methods, in the broadest sense, require practical linking with soft systems...
