Multivariate façade strengthening systems of textured layers in large slab panel buildings

This article presents the solutions of bonded anchors used to strengthen façade textured layers in the walls of three-layer large slab panel buildings in Poland. Large slab panel building systems that are found in Poland have been characterized. The use of new bonded anchors is preceded by diagnostics of the walls of three-layer large slab panel buildings. The author presents two-stage diagnostics: non-destructive methods, measurement of reinforcement parameters and its condition using a Profometer type device, and destructive methods by performing an opencast with a drilling rig. A review of previously used bonded anchorages in Poland was carried out. Proposals for the use of anchor groups in various configurations with different angles of inclination of the diagonal anchors were also presented in order to achieve the most durable effect possible.

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

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).
