Abstarct: In recent decades, the inadequate performance of frxames and infills during earthquakes, particularly in light of the damages observed in the 2017 Kermanshah earthquake (Sarpol-e Zahab county), has highlighted the importance of studying and retrofitting these non-structural elements. Analysis of existing documentation and evidence from this earthquake indicates that a significant portion of the damages resulted from unstandardized or non-existent anchoring of infills, which had serious consequences for building occupants.
The present research aims to retrofit clay block infills both in-plane and out-of-plane using mesh fibers and shotcrete. In this study, the details and dimensions of the frxame and infill have been designed and implemented baxsed on real samples at a 1/2 scale (due to laboratory constraints). In total, six experimental specimens were constructed, comprising two main groups: a) In-plane testing: concrete frxame without infill, concrete frxame with infill, concrete frxame with clay brick infill featuring wall posts and reinforced with alkali-resistant glass mesh fibers and shotcrete; b) Out-of-plane testing: infilled frxame without mesh fibers and shotcrete, concrete frxame infilled with clay bricks isolated from columns (two sides open), concrete frxame infilled with clay bricks using wall posts without mesh fiber and shotcrete reinforcement, and concrete frxame infilled with wall posts reinforced with mesh fibers and shotcrete. It should be noted that in the construction of the infills, full-scale (unmodified) clay bricks were utilized.
The main objective of this research is to control the behavior and retrofit concrete frxames and infills both in-plane and out-of-plane while achieving high-capacity energy dissipation. It is expected that by creating an efficient mechanism, damage from cyclic loading both in-plane and out-of-plane can be prevented, such that energy dissipation occurs significantly.
