How much does a girder bridge cost?
Costs for concrete I-beam bridges range more widely than costs for steel plate girder and rolled steel beam bridges, which have tight pricing ranges. As shown below, costs for concrete I-beam bridges can range from roughly $100/sq. ft all the way to about $580/sq. ft providing for price uncertainty.
What is a concrete girder?
(gûr′dər) n. A beam, as of steel, wood, or reinforced concrete, used as a main horizontal support in a building or bridge.
What is prestressed concrete girder?
Precast prestressed girders are a type of concrete girder that facilitates the rapid construction of a bridge using girders fabricated off-site and then transported and erected into place at the job site.
How much does it cost to build a bridge in South Africa?
the average bridge construction cost was about ZAR15 000 per square meter in South Africa. According to Kruger, this has now risen to around ZAR20 000, making the replacement value of a typical 100m-long, 14m-wide bridge around ZAR28 million.
How much it cost the beam bridge?
How much money does it take to build a beam bridge? As shown below, costs for concrete I-beam bridges can range from roughly R1501. 83/sq. ft all the way to about R8710.
How much are steel beams for a bridge?
Expect steel beams to cost between $0.90 and $1.60 per pound.
What is the length of each girder?
Each girder has a cantilever length of 48 m and an I- shaped cross-section with dimensions shown in the figure. The load on each girder (during construction) is assumed to be 9.5 kN/m, which includes the weight of the girder. Determine the maximum bending stress in a girder due to this load.
What is span of girder?
Plate girder can be used for spans between 10 metres and more than 100 metres (33 feet to more than 330 feet). Stiffeners are occasionally welded between the compression flange and the web to increase the strength of the girder.
What is precast girder?
Precast / Prestressed Bridge Girders are a dominant structural component used to support bridge decks and traffic loads for short to medium span bridges. They provide a low-maintenance, durable and cost-effective solution for both State and County bridges.
How much does it cost to build a land bridge?
While each project is unique and final prices vary, plan on approximately $175 to $350 per square foot of installed bridge.
What does construction cost include?
Construction Cost means and includes the cost of the entire construction of the Project, including all supervision, materials, supplies, labor, tools, equipment, transportation and/or other facilities furnished, used or consumed, without deduction on account of penalties, liquidated damages or other amounts withheld …
What is the price of a beam?
To get a rough idea for the construction cost of rcc beam per sq m, you can get a hint from this formula, however, in general, it is assumed that to construct an RCC beam the approx cost is around Rs 5000 to 5500 per square meter, where the cost for steel, labour, shuttering and material is included.
What is the difference between girder and beam?
Beams are intended to bend to resist and redistribute the load. Girders, on the other hand, are more rigid, as they are there to support the beams and provide the main horizontal support for the structure. The girder is built to support significant, all-encompassing loads such as structural pillars or beam responses.
What size is a girder?
Girder spans also range from 15 feet to 45 feet in 5-foot increments for each of the beam spans noted.
What size are girders?
How thick should a girder be?
Assuming an 8.5-inch composite deck and 2 inch haunch, the minimum steel plate girder depth will be = 67.2 inches – 10.5 inches = 56.7 inches; assuming a minimum top flange of 1 inch and a bottom flange of 1 ½ inches, the minimum web depth will be close to 54 inches.
