Tenders are invited for Construction Of 40.00 mtr span prestressed concrete Box Girder
Bridge at RD C/O link road from Pharal Chachian to village Narial autual name construction of link road to village Narial Panola to village Chachian to connect Hamota Banoli road Km.
There were delays, but the safety record was great and quality was never an issue."<br />The bridge is an extradosed (combining elements of both a prestressed box girder
bridge and a cable-stayed bridge) stay cable segmental concrete box girder
bridge whose main spans measure 600 feet.
Due to closed cross-section geometry of the box girder
bridges, they exhibit a high torsional rigidity which is beneficial in many situations.
Steel box girder
has many advantages, such as much lighter, easy shaped, and can save construction time, and is now become the most common type of the main beam of large span cable-supported bridge.
Cracks appeared on box girder
of the bridge as blasting excavation of nearby Yesanhe Hydropower Station was going on.
The nonlinear temperature distribution will lead to tensile stress along the depth of the sections and also lead to strain difference between the areas outside and inside the box girder
, which are considered to be responsible for thermal cracks and damage .
Segmentally erected box girder
bridges are widely used in order to achieve economy and to obtain high longitudinal and torsional stiffness (Trivedi, 2014; Kwak and Seo, 2002; and 2004).
Seliem  compared old Egptian code (ECP 201-2003) with the new ECP 201-2012 (based on traffic load on bridges of EN 1991-2) by taking concrete I shaped, box shaped and composite girder stated that box girder
yield almost same in both the codes despite the increase in vehicular live loads of ECP 201-2012.
Stevenson knew the exposed site of the bridge and enclosed the trains in a box girder
The high torsional strength of box girder
makes it particularly suitable for sharp curve alignment so as to accommodate to topography along traffic lines, skewed piers and abutment, superelevation, and transitions such as interchange ramp structures.
Steel box girder
bridges are an important and widely used bridge type.
Segmental construction techniques will be required to support the designs created for the bridge, and sources suggest a 1,400m segmental twin box girder
bridge will be installed on the Deira side of the project.
