000015577 520__ $$2eng$$aThe in-plane behaviour of one-bay single-storey reinforced concrete (R/C) frames was numerically examined when they were subjected to cyclic seismic-type horizontal loading and their retrofitting scheme included jacketing of their columns together with a cast-in-place infill R/C panel as an encasement. This numerical study examined the influence of the presence of such an encased R/C panel, being connected with the surrounding frame with or without steel ties, on the overall behaviour of such a system. From the preliminary numerical analysis results it can be concluded that such an encasement results in a considerable increase of the stiffness and the bearing capacity of the studied system, especially when steel ties are present at the interface. Moreover, the placement of steel ties also moderates the amplitude of the forces that are transferred at the narrow column-to-beam joint regions in a direction normal to the interface through the contact/gap mechanism, and consequently, mitigate the possibility of crushing the encased panel and/or parts of the columns or beams at these regions. Consequently, it can be concluded that the presence an encased R/C panel being connected by the appropriate steel ties with the surrounding R/C frame, has an overall beneficial effect on the behaviour of this type of structural system subjected to seismic type loading An experimental sequence was also performed in order to quantify the behaviour of such steel tie connections at the interface under a stress field that is expected to develop at this part of the encasement during seismic type loading. Such measured behaviour is in agreement with the assumptions made concerning the behavioural characteristics of these steel ties in the preliminary numerical analysis
