ABSTRACT

This chapter presents the numerical simulation of the nonlinear behaviour of Textile Reinforced Mortar (TRM)-strengthened masonry panels under in-plane actions. It explores a numerical investigation on the tensile behaviour of TRM composites and shear performance of masonry panels after strengthening with TRMs. TRMs are expected to fulfil moisture compatibility and reversibility requirements for strengthening of masonry and historical structures. The TRM composites were modelled using quadrilateral 8-noded curved shell elements for mortar and embedded grid reinforcement for the grids. Analytical models for TRM-strengthened shear walls do not exist yet. A precise analytical model considering all possible failure modes in TRM-strengthened masonry walls can be of great interest. The performance of strengthened masonry walls was investigated by performing static nonlinear analysis. Two key components of TRMs are the matrix and fibre mesh or grid. The matrix is generally a lime-based or a cement-based mortar. Cement-based mortars are more suitable for structural strengthening of existing reinforced concrete and possibly existing masonry buildings.
