1、Designation: C1577 13aStandard Specification forPrecast Reinforced Concrete Monolithic Box Sections forCulverts, Storm Drains, and Sewers Designed According toAASHTO LRFD1This standard is issued under the fixed designation C1577; the number immediately following the designation indicates the year of
2、original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This specification covers single-cell precast reinforcedcon
3、crete box sections cast monolithically and intended to beused for the construction of culverts and for the conveyance ofstorm water, industrial wastes and sewage.NOTE 1This specification is primarily a manufacturing and purchas-ing specification. However, standard designs per the AASHTO LRFDBridge D
4、esign Specifications are included and the criteria used to developthese designs are given in Appendix X1. The successful performance ofthis product depends upon the proper selection of the box section,bedding, backfill, and care that the installation conforms to the construc-tion specifications. The
5、 purchaser of the precast reinforced concrete boxsections specified herein is cautioned that proper correlation of the loadingconditions and the field requirements with the box section specified, andprovision for inspection at the construction site, are required.1.2 The values stated in inch-pound u
6、nits are to be regardedas standard. No other units of measurement are included in thisstandard.2.

15、ments for Precast Concrete Box Sections Under Earth, Dead and HL-93 Live Load ConditionsNOTE 1Design earth loads and reinforcement areas are based on the weight of a column of earth over the width of the box section multiplied by asoil structure interaction factor as defined in Appendix X1.NOTE 2Con
16、crete design strength 5000 psi.NOTE 3Steel areas are based on an HL-93 live load without the lane load as permitted byAASHTO, using either the design truck or the design tandemand taking the controlling case.NOTE 4The design earth cover indicated is the height of fill above the top of the box sectio
17、n. Design requirements are based on the material and soilproperties, loading data, and typical section as included in Appendix X1. For alternative or special designs, see 7.2.NOTE 5Design steel area in square inches per linear foot of box section at those locations which are indicated on the typical
18、 section shown in Fig. 1.NOTE 6The top section designation, for example, 3 ft by 2 ft by 4 in. indicates (interior horizontal span in feet) by (interior vertical rise in feet) by(wall and slab thickness in inches).NOTE 7In accordance with the acceptance criteria in 7.2, the manufacturer is not prohi
19、bited from interpolating steel area requirements or submittingindependent designs for fill heights between noted increments.NOTE 8The “M” dimension given in the tables is the required distance that As1shall be extended into the top and bottom slabs if it is used asreinforcement for the negative mome
20、nt in these areas. This distance is based on the location where the negative moment in the slab becomes zero, plusan additional development length. Because the live load can be applied at any location along the top slab as the truck drives over it, it is possible forthe “M” dimension to exceed one-h
21、alf the length of the slab.NOTE 9(Advisory)The reinforcing areas are based on 4 inch circumferential wire spacing. Under design conditions where crack control governs,an analysis following the design criteria in Table X1.1 with closer steel spacing may result in a reduction in steel area over those
