The seismic performance of integral abutment bridges (IABs) is affected by the interaction with surrounding soil, and specifically development forces in embankment-abutment soil-piles systems. In principle, these effects could be evaluated means highly demanding numerical computations that, however, can carried out only for detailed studies specific cases. By contrast, a low-demanding analysis ...

Abstract In Simply supported bridge, superstructure and substructure are separated by the expansion joint bearing. Integral bridge (IB), deck is casted monolithically with abutment wall. bridges have increased redundancy, which improves its seismic performance. Bridge fails may fail due to failure of bearing, non‐availability seating width does not occur in IB. The single pile analysis performe...

The survival rate of 1674 bridges and the influence of several factors on the lifetime of bridges were analysed, based on data from patient records that belonged to a random sample of 40 Dutch general practices. It appears that the 12 year survival rate of the bridges is 87%. There is a significant difference in the survival rate between the bridges that meet and do not meet Ante's law, and onl...

Any type of aesthetic correction in dental practice is always a challenging task, especially when it is complicated with cleft lip and alveolus. Careful examination and correct decision making at early stage of treatment and multi disciplinary approach is always necessary for long term success. This paper described a multidisciplinary approach in managing a 19-year-old female patient with unila...

A dental implant is a surgical component that interfaces with the bone of the jaw or skull to support a dental prosthesis such as a crown,bridge,denture,facial prosthesis or even can act as an orthodontic anchor.A variable amount of healing time is required for osseointegration before either the dental prosthetic (a tooth, bridge or denture) is attached to the implant or an abutment is placed w...

Mohammad Muzzammil Department of Civil Engineering, AMU, Aligarh, UP 202002, India E-mail: [email protected] An accurate estimation of the maximum possible scour depth at bridge abutments is of paramount importance in decision-making for the safe abutment foundation depth and also for the degree of scour counter-measure to be implemented against excessive scouring. Despite analysis of...

This paper proposes a multiaxial macroelement for bridge abutments that can be included in the global structural model of to carry out nonlinear dynamic analyses with very much smaller computational effort than achieved using continuum representations embankment and foundation soil behaviour. The proposed derives constitutive force–displacement relationship within rigorous thermodynamic framewo...
