In the reinforcement, there are top slab, bottom slab and outside walls.
Box culvert typical section (6x7), where 6 are inside length and 7 is inside height. Top slab has top main bar and bottom main bar.
Dots signify distribution bars. Bottom slab has top main bar and bottom main bar. Dots signify distribution bars. There’re outside walls with vertical main bars. Dots indicate distribution bars.

New culverts not meeting Design Table requirements and in need of special design. See the Bureau of Local Roads and Streets Manual for guidance on Local Agency culverts. 2.1.3.2 Multi-Barrel Cast-in-Place Concrete Box Culverts For State structures, all new multi-barrel cast-in-place box culverts require a structure number.
There’re bars at 45 degree, known as haunch bars. Wall thickness is 10 inches. Top bar size is #4 @ 6” centre to centre. Bottom bar size is #5 @ 6” centre to centre. Haunch size is #4 @ 12” centre to centre.
Cross-section distribution bars are # 4 @ 12” centre to centre. Vertical bars are # 4 @ 6” centre to centre. Top bars are # 4 @ 6” centre to centre. Bottom bars in bottom slab are # 5 @ 6” centre to centre. Bottom slab is slightly bigger than top slab.
Horizontal length = length – concrete cover
Band is according to slab thickness.
Slab thickness = 10”
Concrete cover (from top and bottom) is 2”
3” band cover is considered
Cut length = length – (2 x concrete cover)
Top bar length = 7.67’
Band = 3”
1’ offset
Concrete cover = 2”
Culvert length = 20’ Box culvert typical section (6 x 7)
r = square root(x2 + y2)
r = square root (1.668 + 1.642)
r = 1.819
Haunch bar total length = 0.5 + 0.5 + 1.819 = 2.819
Numbers = (length – 2 x concrete cover)/spacing + 1
Diameter and length are same in case of distribution bars. [Calculated single time]
Diameter is different in case of top and bottom main bars. [Calculated separately]
Total Length = Bar Length x Numbers x Rows
Weight = d2/52.896
Total Weight = Total Length x Weight/ft

There are many types of construction available in the construction industry; bridge construction is one of them. It is also a part of structural engineering. Bridge mainly builds on the basis of prior imaginary structure.
There are also different kinds of bridges having different kind of structure. Structural engineers or bridge engineers often face difficulties to design structural elements. It is not always possible to design structures with the help of basic bridge structure software. Here the bridge design and analysis spreadsheet comes in handy for the engineers who are associated with bridge engineering.
To achieve quick summary of divergent sections and parts of diversified bridges, the bridge design excel sheet is made. This spreadsheet is particularly aimed for creating the design of different sectors and elements of bridge in accordance with the necessity of engineers.
Here is an important and beneficial list of excel sheets for engineers and construction specialists.
Precast Box Culvert Design
This bridge design excel sheet contains 11 individual excel sheets which are supported with the most recent codes like ACI, AASHTO LRFD, and so on.
