DESIGN OF ANCHOR BOLTS EMBEDDED IN CONCRETE
The nominal axial tensile strength, B an, for headed and bent-bar anchor bolts is taken as the smaller of Equation 11, nominal axial tensile strength governed by masonry breakout, and Equation 12, nominal axial tensile strength governed by anchor yielding. For bent-bar anchors, the nominal axial tensile strength must also be less than that

Different sizes of rebar
The minimum yield strength of standard rebar is 60,000 psi in the USA. If the rebar is not properly placed then the strength of the concrete will be minimized. The concrete's tensile strength can be reduced by 20 percent even if there is an inch extra in spacing. Rebar is needed by the tensile strength of concrete.
• Tearing Strength: the force required either (1) to start or (2) to continue to propagate a tear in a fabric under specified conditions. • Tensile Strength: for geotextiles, the maximum resistance to deformation developed for a specific material when subjected to tension by an external force.

holes is 24 times the thickness of the thinner part (but not more than 12 in.). • Specification J3.6 indicates that the design tension or shear strength of bolts is φ FnAb - Table J3.2 gives the values of φ and Fn - Ab is the unthreaded area of bolt. - In Table J3.2, there are different types of bolts A325 and A490.
Casing Design Calculations From A To Z
Casing Design Calculations For Tensile Strength. The tensile load of the pipe is the weight of the casing which acts to pull the pipe apart. The tension is always the greatest at the surface and decreases with depth due to the casing weight below the point of interest.

Behaviour of grouted anchors
the spall depth is dependent only on the bond strength, the tensile strength of concrete and the hole diameter. With θ = 45 o and using typical values of u/f t, from 3-5, the predicted theoretical concrete spall depth should be between 1-1.5 times the diameter of drilled hole. It has to be noted that the above equations are based on

Structural Bolting Structural Bolting
• When high‐strength bolts are to be tensioned, minimum limits are set on the bolt tension. See AISC Table J3.1 • Tension equal to 70% of the minimum tensile strength of the bolt • Purpose of tensioning is to achieve the clamping force between connected parts. 16

Pull test standards and methods Background The quality of a crimp joint depends on the mechanical strength of the joint as well as its electrical conductivity. If results from pull force tests are within an allowed range, it assures that the proper crimp force has been applied during the crimping process.

wildlife. A ten- (10) strand, high tensile, non-energized fence will cost approximately 2/ 3 of an equivalent woven wire fence. These fences are constructed of 12 ½ gage, class 3 wire, with a minimum tensile strength of 160,000 pounds per square inch (psi), galvanized steel wire. Wire tension for high tensile fences shall be minimum 150-300 lb.

Tensile strength—UHPC has a tensile strength of 1,700 psi, while traditional concrete typically measures between 300 and 700 psi. Flexural strength—UHPC can deliver more than 2,000 psi in flexural strength; traditional concrete normally has a flexural strength of 400 to 700 psi.
• High strength low alloy (HSLA) steel (50,000, 60,000 and 80,000 PSI yield strength) • Heat treated steel (110,000 and 120,000 psi yield strength). Each type has different repair procedures. The frame rail material can be determined by inspecting the frame and consulting the dealer vehicle lineset ticket and the sales data book.

on the hole. As a rule, the strength of the fastener should be such that its total shear strength is approximately equal to the total bearing strength of the sheet material. [Figure 4-2] Torsion Torsion is the stress that produces twisting. While moving the aircraft forward, the engine also tends to twist it to one
Introduction to Tensile Testing
Tensile properties often are measured during develop-ment of new materials and processes, so that dif-ferent materials and processes can be compared. Finally, tensile properties often are used to pre-dict the behavior of a material under forms of loading other than uniaxial tension. The strength of a material often is the primary concern.
