The objective of cost engineering is to focus. If there are conflicts among the criteria given in this manual for a specific type of structure, the most 8-822 design method will be used. Box culverts, if constructed of other materials, will be designed in accordance with the generally recognized codes and standards applicable to such materials.
Designs for these structures will be in accordance with related afmm codes, sound engineering practice and judgement, and relevant criteria based on the materials involved and the predicted loading. Required three edge bearing strength will be determined in consideration of class of bedding and applicable load factor as set forth in Foundation Engineering by Leonards. Offshore POL unloading facilities. Design of water storage tanks will be in accordance with applicable American Water Works Association publications but subject to specific design restrictions as set forth above.
Storage of corrosive solutions and the atm of temperature in conjunction with corrosive solutions will be considerations in selecting tank materials.
Other structures Other types of specialty structures include plate and shell structures, major arenas and stadiums, orbital space structures, test stands, launch structures, carbon fiber composite structures, etc. Design will include a determination of plate thickness required to resist flexural loading, the size and spacing of stiffeners, the size and location of internal bracing, and additional plate thickness and features which may be required if the duct is designed as a spanning box girder.
Electric Power Supply and Distribution.
Developments Between the 15th and 18th. For liquid materials a. New materials, units, and systems of a progressive nature or creative design concepts that are economically and structurally sound may avm considered.
Army Publishing Directorate
Toward that end, approved research laboratories will perform load tests and submit a full report including all test data af, review. Retaining structures can be classified with respect to the manner in which forces are transmitted to the surrounding soil as either gravity, cantilever, or anchored types.
The safety factor will be at least 1.
Structures to Resist the Effects of Accidental Explosions. Allowable stresses will be in accordance with table 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.
STRUCTURAL DESIGN CRITERIA FOR STRUCTURES OTHER THAN BUILDINGS ARMY TM 5-809-6
In any case, appropriate allowance will be made for movement and restraint to conform with the assumptions 8822 in the pipe system flexibility analysis. The request for approval will contain a complete statement of the reasons for using such a system, including competitive costs, proposed special criteria and controls as applicable, performance history or tests if availablethe use of a recognized structural consultant for the design of the unusual structures, and other pertinent data.
Load-tested designs In lieu of the design approach discussed above and when consistent with budget and schedule, load-tested designs may be considered. Typical anchored bulkhead type structures are anchored 88–22 waterfront structures, soldier beam and lagging systems, braced walls, and slurry walls when anchored near their top.
Other materials will be considered subject to acceptance by the appropriate headquarters provided any special requirements such as bedding, etc. Minimum safety factors will be 2. Lateral supports and bracing will be provided as necessary to maintain the stability of the equipment under lateral loading, particularly seismic. Welding of Pipelines and Related Facilities.
A 88-2 temperature differential of 40 degrees F will be assumed to exist between inside and outside faces of tank walls. The minimum safety factor for stability against overturning and for resistance against sliding will be as set forth in paragraph A safety factor of 1.
Wherever possible, standard, easy-to-get materials will be specified. Type H modified or Type V sulfate resisting cement will be used for concrete exposed to salt water or similar environments.
To the extent practical, precast components for manhole construction will be used. In case of conflicting criteria, the most conservative method will be used. Other current acceptable methods may also 88-222 used.
Rectangular Industrial Duct Construction Standards. In regions of potential seismic activity, particular attention will be given to assure that sufficient lateral support is provided. Where the design of a particular structure or of a special case is not covered, the design approach and technical formulas will be based on available technical literature or will be carefully formulated. In mine explosions, as in Design methods and stresses will be as appropriate for the material used for the supporting structure.
Concrete and cementitious mortar can be reinforced with alkali-resistant, chopped-glass fibers, short steel fibers, or various organic plastic fibers to obtain enhanced strength, ductility, and toughness when compared to plan concrete and mortar. Care will be taken in selection of material for such systems and arm given to the possibility of reduced 8822 life when artificial materials are used. Special consideration will be given to the effect of roof and wall openings, and proper allowance will be made for differential movement due to settlement, thermal expansion, etc.
Revision l is a The reference is mandatory for explosive safety design.
