A parametric study for the behaviour of steel plate-anchor assembly embedded in concrete under cyclic loading

Saiwal Krishna

Abstract


Steel plate-anchor assembly embedded in concrete is a common type of connection system used for connecting structural steel members to concrete members. These assemblies are subjected to different loading cases depending on their use. Since the behaviour of such assemblies is quite complex and depends on a number of factors associated with different components, it was decided to adopt finite-element technique to obtain a reasonably accurate analytical solution for the dynamic response. The objective of this study has been to primarily consider the criticality involved in designing the steel-concrete connection that is, the plate anchor assembly, for safe transfer of loads considering that the concrete base can be designed for its adequate strength. A finite element model has been developed and analysed using ABAQUS/CAE 6.5. The finite element model has been validated with experimental data from past studies. The model has been analysed by varying different parameters. Variations of the magnifications of internal stresses in different components of the assembly under cyclic loading over those in case of a static loading have been studied. Finally, a set of design guidelines for determination of magnification of stresses in different components of the assembly, in the context of allowable stress design have been developed.
