2. Tieback (geotechnical) - Wikipedia

   en.wikipedia.org/wiki/Tieback_(geotechnical)

   The magnitude of total anchor force required in the tieback can be determined by analyzing the soil and groundwater properties as well as sources of external loads applied to the system. [ 2 ] The bond length of the tieback must extend beyond the potential critical failure surface of the soil.

3. Anchor bolt - Wikipedia

   They can be further divided into two categories: [3] torque controlled: the anchor is inserted into the hole and secured by applying a specified torque to the bolt head or nut with a torque wrench. A particular sub-category of this anchor is called wedge type. As shown in the figure, tightening the bolt results in a wedge being driven up ...

4. Rail fastening system - Wikipedia

   en.wikipedia.org/wiki/Rail_fastening_system

   Rail anchors, also called anticreepers, are spring steel clips that attach to the underside of the rail baseplate and bear against the sides of the sleepers to prevent longitudinal movement of the rail, either from changes in temperature or through vibration. Anchors may be attached and removed either by hand with hammers, or by an anchor machine.

   A typical lag screw can range in diameter from 4 to 20 mm or #10 to 1.25 in (4.83 to 31.75 mm), and lengths from 16 to 200 mm or 1 ⁄ 4 to 6 in (6.35 to 152.40 mm) or longer, with the coarse threads of a wood-screw or sheet-metal-screw threadform (but larger).

7. Anchorage in reinforced concrete - Wikipedia

   en.wikipedia.org/wiki/Anchorage_in_Reinforced...

   Because the actual bond stress varies along the length of a bar anchored in a zone of tension, most international codes of specifications [2] [3] [4] use the concept of development length rather than bond stress. The same concept applies to lap splice length mentioned in the codes where splices (overlapping) provided between two adjacent bars ...
