TLDR
A behavioral model for determining the distribution of loads to the individual anchors in a connection is presented in this article, which is based on limit design theory, and the model is reported for 28 tests of multiple-anchor connections loaded monotonically by various combinations of moment and shear.Abstract:
Multiple-anchor connections are commonly used in attaching steel members to concrete. A typical connection includes a steel attachment, the anchors that actually do the connecting, and an embedment of the anchors into the concrete. The behavior and design of these connections is not well-defined by existing design standards. Multiple-anchor connections can be divided into two categories, connections for which strength is controlled by the strength of the anchor steel, and connections for which strength is controlled by the strength of the embedment. Based on experimental research, the behavior and design of connections for which strength is controlled by the strength of the anchor steel is addressed. A behavioral model for determining the distribution of loads to the individual anchors in a connection is presented. The model is based on limit design theory. Experimental results are reported for 28 tests of multiple-anchor connections loaded monotonically by various combinations of moment and shear. Test specimens included steel attachments with rigid and flexible baseplates connected to concrete with threaded cast-in-place or retrofit (undercut and adhesive) anchors.read more

TL;DR: The Building Code Requirements for Structural Concrete (Code) as mentioned in this paper covers the materials, design, and construction of structural concrete used in buildings and where applicable in nonbuilding structures, including the strength evaluation of existing concrete structures.

Experimental investigations on concrete cone failure of rectangular and non-rectangular anchor groups
TL;DR: The aim of this experimental study was to investigate the load-displacement behaviour of tension loaded anchor group configurations that are either only partly covered or not covered by the current design provisions, and to generate an experimental database on the concrete cone failure of anchor groups under tension loading.

Outrigger Beam-Wall Connections. I: Component Testing and Development of Design Model
TL;DR: In this article, the authors investigated cyclic behavior of stud groups under combined action of gravity shear and cyclic diaphragm forces, and found that a design method which closely follows available equations for computing stud capacity results in connections that reach the design loads; however, the mode of failure is stud pullout.

Outrigger Beam-Wall Connections. II: Subassembly Testing and Further Modeling Enhancements
TL;DR: In this paper, two 1/4-scale subassemblies that contain a cantilever wall and two outrigger beams with and without floor diaphragms were subjected to cyclic loading and wall reinforcement around the connection was selected according to the anticipated level of cracking and plastic hinge formation.

TL;DR: In this paper, the authors present the results of an experimental investigation on the behaviour of steel column base connections, which is effected by means of a steel base plate welded to the lower end of the column.
Load-deflection behavior of cast-in-place and retrofit concrete anchors subjected to static, fatigue, and impact tensile loads. interim report
TL;DR: In this article, the authors investigate the design and behavior of single cast-in-place and retrofit concrete anchors under static, fatigue, and impact tensile loads, and anchor types were categorized according to these behavior modes.
