Strengthening of Infilled Reinforced Concrete Frames with TRM: Study on the Development and Testing of Textile-Based Anchors

Abstract

The paper presents a technique for strengthening of reinforced concrete infilled frames with textile-reinforced mortar (TRM) jacketing. The key objective of the study is to examine different methods of masonry infill-concrete connection by developing and testing textile-based anchors at the interface between masonry wallettes and concrete. The parameters examined include mainly the type of boundary conditions at the masonry-concrete interface, the geometry and fiber volume of anchors and the type and number of layers of the textile. It is shown that the anchors developed in this study enable the transfer of substantial tensile forces between masonry and concrete and that their magnitude may be estimated on the basis of anchor properties.
