Abstract:
An innovative option to reinforce existing masonry buildings or to increase the load-bearing capacity of
new ones subjected to lateral loading caused by wind or earth pressure is to apply textile reinforcement in render on
the masonry surface or in mortar in the bed-joint. This idea is based on the new material “textile reinforced
concrete” (TRC). However, due to the specific characteristics of masonry compared to concrete, it is necessary to
find suitable textiles for the use in combination with the masonry unit, mortar and render. To achieve a deeper
knowledge on the performance of this composite material, an extensive experimental study is currently carried out.
The main objectives are to identify suitable reinforcing materials as well as to describe the load-bearing and
deformation behavior of textile reinforced masonry under lateral load and hence to derive a design model. Within
this study tests are conducted on small-scale composite specimens under tensile, shear and flexural load, from which
the needed parameters for the design model shall be defined. Basic part of these tests is the investigation of the bond
behavior between textile reinforcement and mortar/rendering under tensile load, for which a new test method for
TRC was implemented. From large scale tests on masonry walls subjected to lateral loading, the effectiveness of
strengthening masonry externally with textile reinforced render will be assessed.
