DESIGN OF EXPANSION ANCHORS TO CONCRETE BASED ON RESULTS OF EXPERIMENTAL VERIFICATION

ABSTRACT: This paper deals with the problems of the fastening of steel structures to concrete constructions using the post-installed anchoring elements. The paper is oriented to the presentation of some results of the analysis concentrated to the actual behaviour of the particular type of steel mechanical anchors, so called expansion anchors, during the loading process. Within the frame of the experimental verification, using the realized tests results and their elaboration, the load-carrying capacities for the corresponding failure mechanisms were obtained. Within the frame of the theoretical analysis, using the tests results statistic evaluation, the probabilistic models were created, for the subsequent reliability analysis leading to the derivation of the characteristic and design resistances. The problems mentioned above were solved for some selected failure mechanisms and load-carrying capacities of expansion anchors under tensile force namely, for static loading actions and eventually for dynamic loading actions.
