Relationship of the interaction load capacity of anchors on their number and anchoring system

Baryłka A., Tomaszewicz D.

Archives of Materials Science and Engineering

2021

Vol. 112, nr 2

55--62

Purpose: The article presents the possibilities of using anchoring systems in the walls of three-layer large slab panel buildings. The use of diagonal anchors allows to increase the effective anchorage depth, which significantly increases the durability of the façade textured layer. Design/methodology/approach: Pilot tests have confirmed the necessity to use an anchor system in various configurations. Findings: The documents used included the conclusions of the pilot tests on the real object and the main experimental tests carried out on concrete samples. Research limitations/implications: The design of new anchorage systems and the proposed theoretical models for estimating their theoretical load capacity are based on the Guidelines contained in the European Technical Approvals. Practical implications: Single bonded anchorages used in engineering practice require evaluation in order to increase the durability of larger areas of the façade textured layer. Originality/value: The possibility of differentiating system anchors makes it possible to use them in very thin structural layers (diagonal anchors).

W pracy przedstawiono wyniki badań in situ na kotwach stalowych różnej długości, mocowanych w murze zabytkowym przy użyciu różnych rodzajów klejów (dwóch epoksydowych i trzech z podatnych polimerów). Wyniki badań zaprezentowano w formie wykresów siła-przemieszczenie z obliczoną energią zniszczenia w każdym przypadku. Zalety i wady sztywnego i podatnego mocowania kotew poddano dyskusji. Przyczyną podjęcia niniejszych badań była awaria zakotwienia taśm CFRP mocowanego na żywicy epoksydowej w budynku zabytkowym.

There was presented in the paper results of investigation in situ on steel anchors of various lengths, fastened in historical masonry wall by 5 kinds of adhesives. Two of them were epoxy resin and three of them were flexible polymers. Research results were presented in form of force-displacement curves with calculation of damage energy of each tested case. Advantages and disadvantages of stiff and flexible adhesives were discussed. The presented case study of CFRP anchorage system fastened in masonry wall using of epoxy adhesive, examined by failure of a historical building, was the reason for the decision on testing of anchor adhesives.
