It requires a specific skill set and special equipment to build box girders
in-house, he adds, noting that beyond the fabrication line, Innovated Industrial has invested in a new automated welding process and uses AWS D14.
In the case of the analysed structure, the curing was carried out through moistening of the fabric covering the horizontal parts of the box girder
The main material in connection with the box girders
was steel rebar, Portland cement, prestressed anchorage and prestressed strand, and the related testing items and methods were as per CNS and ASTM.
In 2006 at BTU and in 2007 at CUT the experimental investigations of a steel knee joint and box girder
respectively strengthened with use of adhesives were carried out.
The steel box girder
spans are continuous and located west of the tied arch spans.
In order to validate the performance of this small box girder
bridge, the two main issues are investigated in experiment for both structural safety and serviceability.
In one of four box girders
of the building massive damage due to leaking drain pipe were found.
3km-long and 36m-wide deck has one of the largest single-cell box girders
used anywhere in the world to build an incrementally launched bridge with prefabricated components.
Since then all viaducts are inspected regularly (viaduct decks are graded twice a year) and the cracks opening in box girders
A composite steel box girders
with a cast-in-place concrete deck will form the $26 million Storrow Drive bridge, which is about 30 meters west of the cable-stayed bridge.
steel box girders
support approximately one-third of the structure
The superstructures of prestressed concrete bridge consisting of two single-celled box girders
