Reinforced concrete stacks will be designed in accordance with ACI Epoxy coated reinforcing bars and densely mixed concrete overlays are considered the most effective methods and are approved by the Federal Highway Administration.
For additional guidelines for concrete bridge structures, adm ACI R. Substation structures and equipment.
Material anisotropy revealed by phase contrast in intermittent contact atomic force microscopy.
In regions of potential seismic activity, particular attention will be given to assure that sufficient lateral support is provided. Design of docks and harbors will, in general, be in accordance with the MIL-HDBK- series which addresses waterfront operational facilities.
The safety factor will be at least 1. Silos, bins, and bunkers. Offshore POL unloading facilities. Storage of corrosive solutions and the effects of temperature in conjunction with corrosive solutions will be considerations in selecting tank materials.
Site wave studies will be performed to determine the effect of wave action on structures. Departments of the Army, 888-22, and Air Force. For that reason, it is important that the agency designing the support structure be familiar with the specifications applicable to the tank. Structures of this type will be designed to avm buoyant forces caused by the presence of water. Water transmission lines Design of water transmission lines will include consideration of items such as maintaining watertightness, avoiding erosive velocities, and providing gradual transitions in crosssection and alignment.
Types of structures not covered include dams and pavements for which guidance can be found in other manuals. Other site structures a.

Fiber-reinforced concrete will be used only if approved by the appropriate headquarters. Equipment supports and enclosures.
Equipment foundations will be designed 88-22 accordance with current practices; the safety factor for stability against overturning and for resistance against sliding will be as set forth in paragraph In general, requirements for materials used in structures other than buildings will be in accordance with paragraph a unless prior approval is amf from the appropriate headquarters. 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 88-222.
Usually, the best way to drain masonry is to put weep holes where they will not adversely affect member strength. Composite construction also includes cast-in-place concrete used in conjunction with structural steel or metal decking. In case of conflicting criteria, the most conservative method will be used.

Design considerations will include forces exerted on the duct system such as those due to gas pressure, dead and live loads, wind loads, snow loads, seismic loads, and loads 88-222 to thermal expansion and contraction. In mine explosions, as in 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.
Reinforced Concrete in Blast-Hardened Structures. Rigid connectors include roughened and adhered surfaces and structural shapes. Water and wastewater treatment structures. Bridge decks subject to repeated applications of deicing salt will require more than additional concrete cover for reinforcing.
There are also a number of options available regarding the type of anchor structure which can be used including anchor wall, batter afk system, earth or rock anchors, etc. Wherever possible, standard, easy-to-get materials will be specified. Minimum safety factors will be 2.
