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

Abstract

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.
