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 [12].
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 [5] 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 construction.
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.
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.
