TL;DR: An orthopaedic method and anchor assemblies for anchoring a linkage such as a rod or cable used for fixation or reduction is described in this paper, which includes an anchor plate and a slotted anchor bolt that captures the plate in a one-piece assembly for convenient installation.
Abstract: An orthopaedic method and anchor assemblies for anchoring a linkage such as a rod or cable used for fixation or reduction. One assembly includes an anchor plate and a slotted anchor bolt that captures the plate in a one-piece assembly for convenient installation. The base of the anchor bolt lies below the plate, and a cap or nut tightens down to secure a linking member, e.g., a rod or cable, in the slot, simultaneously clamping the bolt to fix both its position and its orientation on the plate. One occipital plate has lateral arms that hold the anchor bolts, and a Y-shaped embodiment is mounted in an inverted orientation to position the anchor bolts well down in soft tissue for more effective wound closure. A cable connector is used together with an anchor plate, vertebra anchor screws and fixation rods to secure ends of a cable at the level of one or more vertebrae, providing a versatile and highly stable system for alignment, fixation and fusing of the cervical and thoracic spine. The cable connectors have an open-sided channel that fits onto and securely clamps to an already-positioned fixation rod, with an eyelet or other structure providing a rigid and fixed securing point for a cable that is threaded about the vertebrae under tension. Methods of fixation are described.

TL;DR: In this article, the authors evaluated the tensile breakout capacity of anchor bolts in plain and steel fiber-reinforced normal-and high-strength concrete members and found that the average ratio of measured strengths to those predicted by the Concrete Capacity (CC) method for anchors in plain concrete members was increased from 1.0 to 1.17 with increasing member thickness.

TL;DR: An osteosynthetic anchor bolt has a shaft which has at its front end an external thread having a major diameter greater than the diameter of the shaft and at the rear an internally threaded socket to accept a compression screw as discussed by the authors.
Abstract: An osteosynthetic anchor bolt has a shaft which has at its front end an external thread having a major diameter greater than the diameter of the shaft and at the rear an internally threaded socket to accept a compression screw. The profile of the external thread is designed in such manner that there is maximum possible resistance to axial pressures acting on the anchor bolt frontally, laterally or both.

TL;DR: In this paper, an experimental and analytical study of steel column base plates subject to axial loads and moments is presented for a total of 16 tests were made in which the variables were the anchor bolt size, the base plate thickness, and the ratio of moment to the axial load.
Abstract: The results are presented for an experimental and analytical study of steel column base plates subject to axial loads and moments. A total of 16 tests were made in which the variables were the anchor bolt size, the base plate thickness, and the ratio of moment to axial load. The results of these tests were used to review the two methods of design presently used, one based on the behavior at working load, and one based on the failure load. Both generally produced reasonable predictions of the capacity for the range of variables in this study. The investigation has demonstrated the need for limits of applicability for the two design methods.

TL;DR: In this paper, a post-tensioned pile anchor is used to create a void or highly compressible space between a drilled or driven pile anchor and the bottom of a foundation cap.
Abstract: A post-tensioned pile anchor foundation and method therefor creates a void or highly compressible space between a drilled or driven pile anchor surrounding a post-tensioned anchor bolt or tendon and the bottom of a foundation cap. The void or space can be formed by compressible spacers or void forming elements placed between the top of the pile anchor and the concrete cap. As the anchor bolt or tendon is post-tensioned against the cap, the void forming element is compressed or crushed, allowing the pile anchor to be pulled upwardly toward the cap, developing pull out resistance, and the cap to be pulled downwardly against the surrounding soil to provide a secure foundation for a tower or other structure to be supported thereon.
