Structures associated with the storage and handling of bulk liquid materials will be designed in accordance with the codes and standards applicable to the type of material being handled. If constructed of concrete, design of these types of structures will be in accordance with ACIHandbook of Concrete Engineering by Fintel, and Silos: Intake and discharge structures Intake and discharge structures, such as for power plants and pumping stations, will be designed to sustain wave forces, hydrostatic pressures, earth pressures, surcharges, and other superimposed loads.

Allowable stresses will be in accordance with table Design requirements for timber materials will be in accordance with paragraph a. Where possible, the flexibility of the support structure will be considered to avoid the need for slide bearings or similar construction.

Additional considerations apply to tank design depending on the type of tank and other factors as discussed in the following. Types of structures not covered include dams and pavements for which guidance can be found in other manuals.

Reaction blocking will be designed and provided where necessary to resist forces due to pressure, thrust, impact, water hammer, etc. Effects of Accidental Explosions, Army TM 5 – conservatively predicted the blast pressure loadings obtained from the pressure transducers mounted on the Design requirements for aluminum materials will be in accordance with paragraph 22a.

For bridges or structures exposed to corrosive chemicals or deicing salt, epoxy coated reinforcing bar, a densely mixed overlay, or both will be provided to prevent corrosion of reinforcing steel. Intake and discharge structures. Welding of Pipelines and Related Facilities.

Other forces including those due to wind, snow, seismic activity, thermal expansion and contraction, thrust, impact, etc. Anyone wishing to make further use of any copyrighted material, by itself and apart from this text, should seek necessary permission directly from the proprietors.

Design Handbook-Precast and Prestressed Concrete. The allowable stress is for a design condition of dead load combined with either seismic or wind loads. For that reason, it is important that the agency designing the support structure be familiar with the specifications applicable to the tank.

Specific guidance should be obtained from local or state highway department officials. This will not preclude, however, the use of new codes or specifications which, although less conservative, are considered acceptable for military construction.

Epoxy coated reinforcing bars and densely mixed concrete overlays are considered the most effective methods and are approved by the Federal Highway Administration.

Composite construction also includes cast-in-place concrete used in conjunction with structural steel or metal decking. For design of structures associated with power plants, see applicable portions of TM Basins and similar construction. The minimum safety factor for arm against overturning and for resistance against sliding will be as set forth in paragraph Dockside Utilities for Ship Service.

Material anisotropy revealed by phase contrast in intermittent contact atomic force microscopy.

Consideration will be given to the need for and alternate means of accomplishing corrosion protection of the underside of the tank floor plates. In addition, the design will consider the effects of elevated temperature which can reduce the yield point and other mechanical properties of steel. Additional guidance for watertight construction and load distribution coefficients for these types of structures may be found in PCA IS 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.

Design of reinforced concrete tanks will be in accordance with PCA Textbooks and Handbooks Suresh C. Materials Used in Civil Engineering. For individual leg foundations, the weight of the foundation alone not considering weight of the earth cover will provide a minimum safety factor of 1. Structural strength and stability will be considered, as well as the need for ventilation and other services.

Box culverts, if constructed of other materials, will be designed in accordance with the generally recognized codes and standards applicable to such materials. Gas and air conveyances Gas and air conveyances, particularly for hot gases, will be designed to meet fire protection requirements including National Fire Protection Association NFPA Manual for the Design of Hollow Core Slabs. The structural design will be coordinated with the selection of pipeline materials and layout to assure that proper allowance has been made for these forces as well as expansion movements, etc.

Precast Reinforced Concrete Manhole Sections.

Material anisotropy revealed by phase contrast in intermittent contact atomic force microscopy.

Equipment foundations will be designed in accordance with current practices; the safety factor for stability 8-822 overturning and for resistance against sliding will be as set forth in paragraph Concrete properties will be selected to suit the expected conditions. Minimum safety factors will be 2. The amount of trash, debris, or seaweed expected to accumulate in intake structures will be the primary consideration in deciding whether or not a continuously cleaning mechanical acm screen will be used.

Structures to Resist the Effects of Accidental Explosions. Rigid connectors include roughened and adhered surfaces and structural shapes.

STRUCTURAL DESIGN CRITERIA FOR STRUCTURES OTHER THAN BUILDINGS ARMY TM

Miscellaneous structures Miscellaneous structures are those not listed elsewhere in this manual or not covered by a specific code or specification. Offshore POL unloading facilities. Information describing any new load-tested materials or systems determined necessary, advantageous, and economical will be submitted for approval to appropriate headquarters.

Pipelines and supports Design requirements for pipelines and their supports will depend on the nature of the material being transported and the materials used for construction. Other current acceptable methods may also be used.
