Numerical Study of Out-of-Plane Behaviour of Timber Retrofitted Masonry Prisms

== Abstract ==

The present study addresses the retrofitting of running-bond masonry walls through the application of oriented strand board (OSB) timber panels aiming to increase the masonry flexural strength and deformation capacity under out-of-plane actions. This paper presents the numerical  analysis  of masonry  prisms  to  complement  the information  provided  by  the experimental  campaign  developed  on  flexural  performances  of  timber  retrofitted  masonries. The  numerical  model  represents  the  masonry  components  (brick  and  mortar)  as  a  three-dimensional volume via volumetric finite elements, i.e. hexahedral 8-node linear brick elements with reduced integration and hourglass control. The nonlinear properties of the mortar joints and the brick units have  been calibrated through  information that resorts from experimental characterization  tests.  The  numerical  damage  pattern  and  load-displacement  capacity  curve are  compared  with  the  experimental  observations.  A  good  agreement  has  been  found  and, therefore, the calibrated model can be employed in parametric studies, to further analyse the efficiency of the proposed timber masonry retrofit technique, and to more complex structural study cases.
