CONCRETE CULVERT DESIGN AND DETAILING MANUAL2003 03 142DEFINITIONSPage 3DEFINITIONSApron Wall - Also known as a cutoff wall; a vertical non-structuralconcrete wall built across the full width of the ends of box culverts andextending below the level of the bottom slab.Bar Mass - The mass of a reinforcing bar per unit length (kg/m).Bearing Capacity - The maximum load that can be applied to a soil at therespective limit state.Box Culvert - A culvert in the shape of an enclosed rectangle andconsisting of a bottom slab, two wall elements and a top slab.Culvert Extension - A portion of a culvert built beyond the limits of apreviously existing culvert.Designer - Individual(s) designated by the Structural Engineer to use thismanual to design and detail culverts.Fill Height - The vertical distance from the top of the top slab of a culvertto the riding surface of the roadway above it.Geotechnical Engineer - A licensed professional engineer designated aspecialist in the soils or geotechnical field.Haunch - The increase in thickness of a culvert's walls or slabs at thecorners.Header Wall - A vertical concrete wall across the full width of the ends ofa culvert and extending upwards from the level of the top slab.Height - For box culverts this is the vertical distance measured from thetop of the bottom slab to the bottom of the top slab at mid-span. For openfooting culverts this is the vertical distance measured from the level of thetop of the footings to the bottom of the top slab at mid-span.Length - The length of a culvert is the distance between the ends, alongthe longitudinal axis of the culvert.Longitudinal Axis - The longitudinal axis of a culvert is located at thegeometric centroid of the culvert cross-section and is parallel to the wallsof the culvert.
CONCRETE CULVERT DESIGN AND DETAILING MANUAL2003 03 14DEFINITIONSPage 4Non-Rigid Frame Culvert - A non-rigid frame culvert is one detailed sothat there is no intended transfer of bending moment between wall andslab elements.Open Footing Culvert - A culvert in the shape of an open rectangle,consisting of two wall elements supported on footings and a top slab. Notethat there is no bottom slab.Retaining Wall - A retaining wall for the purpose of this Manual is anearth retaining structure consisting of a vertical stem element supportedby a horizontal footing element and built of reinforced concrete.Rigid Frame Culvert - A rigid frame culvert is one detailed so that fullcontinuity of bending moment is assured between the wall and slabelements.Set - A set of longitudinal reinforcing bars refers to the placement of areinforcing bar in a specific location on a cross-section.Skew Angle - The skew angle is the angle between the centreline of thehighway and a line perpendicular to the longitudinal axis of the culvert.Skew Number - The skew number is the angle between the centreline ofthe highway and the longitudinal axis of the culvert, measured clockwise.Skewed End Culvert - A skewed end culvert is one with ends not at aright angle to the longitudinal axis of the culvert. Usually the ends are builtat right angles to the longitudinal axis of the culvert.Span - The span of a culvert is the minimum horizontal distancemeasured between the inside faces of the walls.Standard Culvert - A culvert detailed in accordance with this Manual.Structural Engineer - A licensed professional engineer of Ontariospecializing in structural design.Strut - A member placed between the footings of an open footing culvert.Traversable Grate - A safety grating over the open tapered ends ofconcrete culverts that do not have traffic protection.

CONCRETE CULVERT DESIGN AND DETAILING MANUAL2003 03 14GENERAL INFORMATION4GENERAL INFORMATION4.1INTRODUCTION4.1.1SCOPEPage 7This Manual contains all data necessary to complete the standarddrawings and quantities for concrete box and open footing culverts that fallwithin the size range of "Standard Concrete Culverts" specified in Sections4.2.1 and 4.2.2. Data is also provided to permit the detailing of:i.Simple retaining walls for use with these culverts.ii.Intersecting drains, catch basins and manholes.iii.Culverts with skewed ends.The Manual provides quantities per unit length of culvert but no data isprovided for the calculation of extra quantities for footings, apron andheader walls or for retaining walls. Concrete quantities are in cubicmetres and steel quantities are in kilograms. Provision is made on thedrawings for inserting a breakdown of quantities for progress paymentpurposes. The Designer must compute these quantities.4.1.2DESIGN CRITERIADesign and detailing data contained in this Manual conforms to therequirements of the 2000 edition of the Canadian Highway Bridge DesignCode with the exception of the criteria listed in the Appendix. Calculationsare based on 30 MPa concrete and grade 400 reinforcing steel.4.1.3LIMITATIONSThe following topics are considered to be beyond the scope of thisManual:i.Selection of culvert type and size, and all information usuallyshown on form PH-D-353, or DB-RD-77 or “Design Data Formfor Concrete Culverts”.ii.Culverts with less than 0.6 m fill (require special attention).iii.Culverts with skew angle exceeding 25 .

Single W-beam guardrail with Jong span across culvert, and 4. Nested W-beam guardrail with long span across culvert. The culvert was assumed to have a minimum soil cover of 18 in. (45.7 cm).
An existing SRH-2D model will be used to facilitate the setup for this tutorial. SRH-2D provides two different ways to define a culvert. The recommended method to simulate a culvert in SRH-2D is to couple the FHWA HY-8 culvert model with SRH-2D. This tutorial will demonstrate this. The second approach for simulation of a culvert involves
