DESIGN NOTES
<br />SPECIFICATIONS:
<br />DESIGN: A.A.S.H.O. DATED 1957 WITH REVISIONS AND AS SUPPLEMENTED
<br />BY BRIDGE PLANNING AND DESIGN MANUAL.
<br />SECTIONS DESIGNED FOR CULVERT IN A TRENCH ON HARD
<br />FOUNDATION, OR CULVERT UNTRENCHED ON YIELDING
<br />FOUNDATION. FOR CULVERTS ON PILES OR ROCK
<br />FOUNDATIONS SPECIAL DESIGN WILL BE REQUIRED.
<br />LOADING:
<br />LIVE LOAD = H2O-S16-44 OR ALTERNATIVE WITH 30% IMPACT FOR ALL COVER
<br />DEPTHS. NEGLECT LIVE LOAD WHEN ON SINGLE SPANS, COVER
<br />IS MORE THAN WAND EXCEEDS SPAN, AND ON MULTIPLE SPANS
<br />WHEN COVER EXCEEDS DISTANCE BETWEEN EXTERIOR WALLS.
<br />CULVERTS AT GRADE TREATED AS A BRIDGE, WITH THE WHEEL LOAD
<br />ON THE INVERT SLAB DISTRIBUTED OVER 7.5' TRANSVERSLY AND
<br />THE BREADTH OF THE CULVERT LONGITUDINALLY.
<br />WHEEL LOADS DISTRIBUTED UNIFORMLY OVER A SQUARE, THE
<br />SIDES OF WHICH ARE 1.75 TIMESTHE DEPTH OF FILL, BUT
<br />NOT LESS •TRANSVERSLY THAN THE DIMENSION FOR GRADE TOP
<br />ON THE TOP SLAB, AND NOT LESS THAN 7.5' ON THE INVERT
<br />SLAB. WHEN SUCH AREAS FROM SEVERAL CONCENTRATIONS
<br />OVERLAP, THE TOTAL LOAD SHALL BE CONSIDERED AS UNIFORMLY
<br />DISTRIBUTED OVER THE AREA DEFINED BY THE OUTSIDE LIMITS
<br />OF THE INDIVIDUAL AREAS, BUT THE TOTAL WIDTH SHALL NOT
<br />EXCEED THE TOTAL WIDTH OF THE SUPPORTING SLAB.
<br />DEAD LOAD: EARTH LOAD OF 120 LBS. PER CU. FT. AND AN EQUIVALENT
<br />FLUID PRESSURE OF 36 LBS. PER SO. FT. ( BOTH REDUCED
<br />30% FOR BALANCED DESIGN) .
<br />DISTRIBUTION OF WHEEL AT GRADE; E =. 175S + 3.2
