Demolition of a 65‐year‐old box‐girder prestressed concrete bridge located in Northern Sweden

چکیده

Abstract A new bridge was built in Kalix, northern Sweden, to replace an existing prestressed concrete box‐girder that had been service for over 60 years. The old a total length of 283.6 m divided into five spans: 43.9 m, 47.0 94.0 and m. It constructed using the balanced cantilever method with segments having lengths around 3.0 need replacement arose from recommendations extracted assessment bridge's state capacity. In addition construction bridge, its necessitated creation evaluation demolition procedure bridge. This be carefully designed avoid damaging stability‐related issues but also prevent debris falling Kalix River, which is part Natura 2000 protected area. paper discusses various considered while developing strategy, including use bed‐rock anchored tendons, intermediate support fixing at specific locations, proper position equipment supported by among others. problem disposing demolished material discussed.

Optimization of Precast Prestressed Concrete Bridge Girder Systems

60 A practical approach to the optimal design of precast, prestressed concrete highway bridge girder systems is presented. The approach aims at standardizing the optimal design of bridge systems, as opposed to standardizing girder sections. Structural system optimization is shown to be more relevant than conventional girder optimization for an arbitrarily chosen structural system. Bridge system...

First Smart Prestressed Concrete Highway Bridge in Canada

Deterioration of concrete members due to corrosion of steel reinforcements is one of the major problems which reduces the service life time of bridges, especially in Canada due to the use of de·icier applications. The cost of correcting corrosion-induced distress in bridges is high compared to the capital cost of the structure. To overcome this problem, the City of Calgary has decided to constr...

Effects of Temperature Variations on Precast, Prestressed Concrete Bridge Girders

The monitoring of a precast, prestressed girder bridge during fabrication and service provided the opportunity to observe temperature variations and to evaluate the accuracy of calculated strains and cambers. The use of high curing temperatures during fabrication affects the level of prestress because the strand length is fixed during the heating, the coefficients of thermal expansion of steel ...

Hysteretic Behavior of Prestressed Concrete Bridge Pier with Fiber Model

The hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier were researched. The effects of the prestressed tendon ratio, the longitudinal reinforcement ratio, and the stirrup reinforcement ratio on the hysteretic behavior and seismic characteristics of the prestressed concrete bridge pier have been obtained with the fiber model analysis method. The analysis show...

An Investigation on Transversely Prestressed Concrete Bridge Decks

This study is concerned with the development of design specifications for the use of transverse post-tensioning in concrete bridge decks. The ultimate goal behind this proposal is to improve the durability of concrete bridge superstructures. Experimental results from previous studies are used to validate the analytical models implemented in the development of the design specifications. It is fo...
