Offshore POL unloading facilities.
Earth cover will be provided over the top of tanks acm accordance with frost penetration requirements considering concrete distribution slab thickness but will be not less than 2 feet 6 inches. Box culverts, if constructed of other materials, will be designed in accordance with the generally recognized codes and standards applicable to such materials.

Purpose This manual establishes structural design criteria for structures other than buildings, furnishes design guidance for various types of structures, and identifies special considerations with regard to certain materials in specific applications.
In case of conflicting criteria, the most conservative method will be used.

Other acceptable standard design methods or concepts may also be used. Except for foundation elements, a structure or any of its elements will be designed to provide a minimum safety factor of 2. In any case, appropriate allowance will 888-22 made for movement and restraint to conform with the assumptions made in the pipe system flexibility analysis. Other current acceptable methods may also be used. For that reason, it is important that the agency designing the support structure be familiar with the specifications applicable to the tank.
This approach can be applicable to certain composite type structures or components such as those involving adhesive bonded elements, cellular foam, and newly developed materials.

For a general discussion of considerations such as material selection, service life, etc. If constructed of concrete, design of these types of structures will be in accordance with ACIHandbook of Concrete Engineering by Fintel, and Silos: Care will be taken to assure that the natural frequency of supports is sufficiently offset from the operating frequency of the equipment so that afj is no danger of objectionable or damaging resonant vibration. Revision l is a Design of below-grade or buried 882-2 will consider the potential bouyancy of the tank, and a suitable ballast slab or other anchoring system will be provided to assure that the tank will not float when the dead weight of the empty tank and soil cover directly over the tank are insufficient to prevent flotation.
Intake and discharge structures. Open canopies include unenclosed roofed areas and one- two- and three-sided enclosures. Paved inverts and similar details will be provided as required for the particular system 88-222 incorporated.
STRUCTURAL DESIGN CRITERIA FOR STRUCTURES OTHER THAN BUILDINGS ARMY TM 5-809-6
For design of structures associated with power plants, see applicable portions of TM The minimum safety factor for stability against overturning and for resistance against sliding will be as set forth in paragraph This type of steel will not be used in areas where the atmosphere contains salt spray and will not be used in a seawater environment.
Electric Power Plant Design. Developments Between the 15th and 18th.

Consideration will be given to the need for and alternate means of accomplishing corrosion protection of the underside of the tank floor plates. Equipment supports and enclosures. Care will be taken in selection of material for such systems and regard given to the possibility of reduced service life when artificial materials are used.

Round Industrial Duct Construction Standards. This type of steel will not be used in buried structures unless coated nor will it be used in locations where rust staining of the supporting elements is objectionable.
Blast-resistant design is often required in conjunction with the construction of fam system facilities, both developmental and operational, as well as for structures designed to resist the effects of intentional attack. Scope Structures other than buildings which are covered by this manual include the following: Composites and structural plastics have limited applicability to military construction and then only to selected specialty structures.
Required three edge bearing strength will be determined in consideration of class of bedding 8822 applicable 88-222 factor as set forth in Foundation Engineering by Leonards. Basins and similar construction. Additional consideration will be given to possible load increases which can result from irregularities in alignment of the support system over which the structures will be moved, e.
In regions of potential seismic activity, particular attention will be given to assure that sufficient lateral support is provided. The design agency will verify that appropriate impact factors have been included in loads provided by the conveyor system manufacturer. Trash racks and afn will be provided.
To the extent practical, precast components for manhole construction will be used. Other forces including those due to wind, snow, seismic activity, thermal expansion and contraction, thrust, impact, etc.

The concrete mixture will be of maximum density and minimum shrinkage, especially with regard to longtune shrinkage and expansion which may be caused by alternate wetting and drying. However, the adequacy of these design procedures is not well defined Mobile canopies and shelters will be designed for the loads which would otherwise apply to stationary structures of that type with additional provisions regarding impact factors appropriate for the speed at which the structures are to be moved.
Load-tested designs In lieu of the design approach discussed above and when consistent with budget and schedule, load-tested designs may be considered. Design of main pier or wharf structures will consider conditions of exposure and loadings applicable to the location and service af, which the structure is intended. General Design of structures for bulk materials will include consideration of the special characteristics of the material being handled or stored.
Concrete properties will be selected to suit the expected conditions.
