Abstract

This paper studies the structural response of masonry walls strengthened with externally bonded composite materials to resist in-plane shear loading. The paper focuses on the parametric sensitivity of various aspects of the response to the geometrical and mechanical properties of the mortar joints. The impact of these parameters, which inherently involve diversity and uncertainty, on the global and, particularly, the local responses of the strengthened masonry assembly is examined. To achieve this, a multi-layered specially tailored finite element formulation is adopted. A super-element approach is used for the reduction of the computational load. The numerical and parametric studies quantify the sensitivity of the structural response and designate cases in which substandard but yet realistic and reasonable estimation of the elastic and geometrical properties may lead to a critical underestimation of the interfacial stresses and the stress resultants in the FRP system.
