Three‐dimensional testing of fasteners

Abstract: Experimental results of tests to investigate the load‐bearing behavior of anchor channels embedded in concrete and subjected to loads in three‐dimensional (3D) interaction are presented. For testing, a variably adjustable rig is introduced in which arbitrary 3D loads are applied with just one hydraulic cylinder. Investigations focus on concrete failure. The test program includes variable load angles and anchor channels installed at the edges and at corner of concrete prisms. In both configurations a significant impact of the loading direction regarding the channel axis is found. Mathematically interaction is captured with trilinear and Lamè curves. Therein, the experimental findings are reflected by individual model parameters that yield the best fit in regression. For both configurations, an optimal prognosis model is derived which covers all 3D load situations in assured quality. Moreover, the tests prove the general suitability of the developed rig, which thus qualifies for application in other experimental settings.
