Fill = 5.00000 Ft.
Tire patch width = 20.00000 In.
Equiv. strip width = FILL*1.75+TPATW/12+16 = 26.41667 Ft.

Number of cells = 1
Top Slab thickness = 12.0000 In.
Bottom Slab thickness = 12.0000 In.
Exterior Wall thickness = 12.0000 In.
Design Span(c-c walls) = 15.0000 Ft.
Design Height(c-c slabs) = 6.0000 Ft.
Fill Height(top of slab) = 5.0000 Ft.
Wearing surface thickness = 10.0000 In.
Loads based on 1 foot unit width
Soil Structure Interaction Factor = 1.1500
Earth Weight for fill computations = 0.1380 Kcf
Weight of Fill without wearing surface = 0.5750 Klf
Weight of Wearing Surface = 0.1208 Klf
Weight of Top Slab = 0.1500 Klf
Weight of Extra Uniform Dead Load = 0.0000 Klf
Uniform Dead Load on Top Slab = 0.8458 Klf
Weight of Walls divided by culvert width = 0.0938 Klf
Uniform Dead Load on Bottom Slab = 0.9396 Klf
Soil pressure at center of top slab = 0.3300 Klf
Soil pressure at center of bottom slab = 0.6900 Klf
Soil pressure due to live load surcharge = 0.0600 Klf
Impact Factor on Top Slab & Walls = 0.0000
Impact Factor on Bottom Slab = 0.0000
Axle Load Distribution Factor on:
Top Slab & Walls = 0.0757
on Bottom Slab = 0.0757
Note:
1. The weight of the walls is computed by taking the
interior wall thickness plus twice the exterior wall
thickness and multiplying by the clear height of the
culvert and the weight of concrete. That result is
divided by the span length times the number of cells
plus the wall thicknesses.
2. The soil pressure computations use the fill height
and the culvert height for appropriate values for
lateral earth pressures. Wearing surface, fill
height, and slab thickness are used in vertical dead
load computations.
3. The distribution width and associated distribution
factor for the top slab is computed according to
3.24.3.2 for fill depth less
than 2 ft. and 6.4 for fill
depths over 2 ft.

For a HS20T Vehicle
Description AASHTO HS20-44 (MS 18) TRUCK (US)
The number of simulated axles based on fill = 26
The number of simulated axles is calculated based
on the longitudinal distribution length of each axle
divided by the simulated axle spacing of 1 foot
and the simulated axle weights are calculated by
dividing the vehicle axle weights by the number of
simulated axles per vehicle axle.

Notes:
1. Area of steel is the maximum required for all
limit states. The strength computations are shown in
the results at critical sections table.
2. Design thickness shown in the following table is
based on the appropriate cover minus half the diameter
of the bar in the above table or one-half
the diameter of a #6 bar. The actual half bar diameter
is used once the steel has been selected
and the #6 bar is used in design iterations.
3. For a Design review run the actual bar stresses shown
can be the stress at either side of a member corner or
the stress at the middle of the slab for a multiple cell
group. The required As is actual in a Design review.
4. If the user wishes to ignore crack control the allowable
steel stress is set at 0.95 Fy. This limit will likely
not control the design, but it if should, this will
control yielding under service loads.

Warnings:
1. For exterior corners, BRASS-CULVERT does not perform a check on both
the exterior wall and top or bottom slab.
BRASS-CULVERT only checks the location that it has determined
requires a greater area of steel. Because of
this, BRASS-CULVERT may check one location for a particular culvert
(e.g. top of the wall) and a different
location (e.g. left end of top slab) for the same culvert with a
different depth of fill.

Notes:
1. Flexure rating value of n/a indicates no live load effect on the
member
2. SS value adjacent to steel area indicates a simply supported culvert
and a steel area is not required
3. AASHTO 8.16.4.2
Po -- Axial capacity at zero eccentricity (no moment)
Mu -- Flexural Capacity without an axial load
Pbal -- Axial load at balanced strain
Mbal -- Moment at balanced state of strain
4. The phi factors are included
5. Coin. is the coincident axial force
6. The plane of computation for shear is a "d" distance
from the face of the supporting member
7. The plane of computation for moment if haunches are
used is based on AASHTO 8.8.2
8. The plane of computation for moment if haunches are
not used is based on the user input
9. An asterisk next to the Design Moment indicates the
Moment is greater than the All Mom. Value
10. An asterisk next to the Shear Value indicates the
Shear is greater than the Allowable Shear
11. Rating factors computations consider the effect of
axial force. The Allowable Moment value is used
with the maximum soil pressure.
12. The load combinations and envelope of critical action
combinations are shown in the
C:\BRASS\Culvert\ODOT\R120568.ooo file.
13. For fills less than 2.0 feet, Article 3.24.4
applies, and shear is assumed to adequate because
the section has been designed for moment.

Warnings:
1. For exterior corners, BRASS-CULVERT does not perform a check on both
the exterior wall and top or bottom slab.
BRASS-CULVERT only checks the location that it has determined
requires a greater area of steel. Because of
this, BRASS-CULVERT may check one location for a particular culvert
(e.g. top of the wall) and a different
location (e.g. left end of top slab) for the same culvert with a
different depth of fill.

The number of simulated axles based on fill = 23
The number of simulated axles is calculated based
on the longitudinal distribution length of each axle
divided by the simulated axle spacing of 1 foot
and the simulated axle weights are calculated by
dividing the vehicle axle weights by the number of
simulated axles per vehicle axle.

Warnings:
1. For exterior corners, BRASS-CULVERT does not perform a check on both
the exterior wall and top or bottom slab.
BRASS-CULVERT only checks the location that it has determined
requires a greater area of steel. Because of
this, BRASS-CULVERT may check one location for a particular culvert
(e.g. top of the wall) and a different
location (e.g. left end of top slab) for the same culvert with a
different depth of fill.

The number of simulated axles based on fill = 27
The number of simulated axles is calculated based
on the longitudinal distribution length of each axle
divided by the simulated axle spacing of 1 foot
and the simulated axle weights are calculated by
dividing the vehicle axle weights by the number of
simulated axles per vehicle axle.

Warnings:
1. For exterior corners, BRASS-CULVERT does not perform a check on both
the exterior wall and top or bottom slab.
BRASS-CULVERT only checks the location that it has determined
requires a greater area of steel. Because of
this, BRASS-CULVERT may check one location for a particular culvert
(e.g. top of the wall) and a different
location (e.g. left end of top slab) for the same culvert with a
different depth of fill.

Description OHIO LEGAL LOAD 5C1 TRUCK (US)
The number of simulated axles based on fill = 35
The number of simulated axles is calculated based
on the longitudinal distribution length of each axle
divided by the simulated axle spacing of 1 foot
and the simulated axle weights are calculated by
dividing the vehicle axle weights by the number of
simulated axles per vehicle axle.

Warnings:
1. For exterior corners, BRASS-CULVERT does not perform a check on both
the exterior wall and top or bottom slab.
BRASS-CULVERT only checks the location that it has determined
requires a greater area of steel. Because of
this, BRASS-CULVERT may check one location for a particular culvert
(e.g. top of the wall) and a different
location (e.g. left end of top slab) for the same culvert with a
different depth of fill.

Description AASHTO ALTERNATE MILITARY LOADING (US)
The number of simulated axles based on fill = 13
The number of simulated axles is calculated based
on the longitudinal distribution length of each axle
divided by the simulated axle spacing of 1 foot
and the simulated axle weights are calculated by
dividing the vehicle axle weights by the number of
simulated axles per vehicle axle.

Warnings:
1. For exterior corners, BRASS-CULVERT does not perform a check on both
the exterior wall and top or bottom slab.
BRASS-CULVERT only checks the location that it has determined
requires a greater area of steel. Because of
this, BRASS-CULVERT may check one location for a particular culvert
(e.g. top of the wall) and a different
location (e.g. left end of top slab) for the same culvert with a
different depth of fill.
