Dec 1, 2012 · Experimental and theoretical studies of drag embedment plate anchors recently carried out in Tianjin University are summarized in this research paper, which involve a series of important topics relevant to the study of drag anchors. The techniques for measuring the trajectory and movement direction of drag anchors in soils, the
Nov 15, 2021 · This would be a handy joint type to have since embed plates are a fairly common condition with projects having concrete walls. We normally switch over from RAM Connection to programs from the various post-installed anchor vendors (DeWalt, Simpson, Hilti, etc) since they usually have headed studs as an option even though they're not manufacturing those.
installed anchors (Fig. 3) with shallow embedment have become very popular for anchoring suspended mechanical, electrical, and air conditioning equipment, and piping and conduit applications in buildings. In most cases, cast-in Fig. 1: Anchorage of nonstructural loads with shallow embedded anchors. This example shows a redundant system with four
These test series had 24 total tests in 406-mm thick test slab specimens using 12.7-mm diameter studs. The first two tests in a series used studs with an effective embedment depth (hef) of 67.7 mm; longer studs with hef= 124 mm were used for the second two tests.
Use of Headed Studs Embedded in a Grout Beam. Do not count on the full capacity of the stud as documented in AISC 360-10, which is intended for shear transfer from a beam into a slab which provides significant lateral confinement to the concrete in the vicinity of the shear stud.
Program Assumptions and Limitations: 1. This spreadsheet program is intended to analyze and design the embedment of four headed concrete anchors affixed to a rigid plate. Shear and tension embedment strength is calculated per Appendix D of ACI 318. The bearing capacity is calculated per Section 10 & 11 of ACI 318.
