Debris-flow impact plays a significant role in the failure of bridges mountainous areas posing risk to human life and leading high reconstruction costs. The aim this study is measure quantify frontal forces debris flows on bridge superstructures based laboratory experiments with special regard comparison two different profiles presence / absence pier. To end, we conducted 20 experiments, measur...

Many dental practitioners do not use adhesive bridges because of concerns over high failure rates. Techniques for these restorations should be based on the fundamental principles of bridge design which require rigid, accurately fitting frameworks and careful control of the occlusion. The abutments generally require little if any tooth preparation. Greater security will result from more extensiv...

The construction of integral bridges is one the most effective methods to reduce bridges’ and in-service costs. However, there are associated geotechnical problems with their abutments backfill due integrated abutments. main goal this study evaluate quantify benefits geogrid reinforcement for reducing backfill’s problems. For purpose, using small-scale physical modeling, reinforcing an abutment...

Presented here is a granular soil model created to investigate the soil pressures which develop behind integral bridge abutments. The problem is introduced along with a brief summary of the fundamental behaviour, the model produced, and the initial validation. The paper looks at the initial outcome of the final validation procedure where experimental behaviour of an abutment is compared to the ...

It is reported that the inclined pile could be either beneficial or detrimental for abutment they support in condition of liquefaction—induced lateral displacement. To clarify effect on seismic response bridge abutments undergoing displacement, numerical analyses were carried out damaged was supported by piles and displaced riverwards 100 mm–150 mm due to soil liquefaction during 2011 Great Eas...

This paper presents the fully base-isolated highway bridge benchmark problem. The highway bridge benchmark problem consists of two phases: (1) Phase I—the bridge deck being base isolated only at the abutments and the center bent being integral with the pier (without isolation), and (2) Phase II—the bridge deck being fully base isolated at both the bent/pier and abutment locations. In both phase...

The aim of the retrospective study was to assess the clinical and radiographic outcome of the dental implant surgery and prosthetics. It was conducted at the Aga Khan University Hospital, Karachi, and comprised of medical charts and radiographic records of patients visiting between 2010 and 2015. Variables such as implant dimensions, final prosthesis, method of retention, loading protocol and p...

Bridges are potentially one of the most seismically vulnerable structures in the highway system during earthquake &#10 &#10events. It is known that the seismic performance of transportation systems plays a key role in the post-earthquake emergency management. Hence, it is necessary to evaluate both physical and functional aspects of bridge structures. The physical aspects of the seismic perform...
