Testing of confined masonry walls with different connection details

According to the Eurocodes horizontal and vertical confining elements should be bonded together and anchored to masonry by manner of construction (toothing) or by mechanical connectors (dowels). Both methods cause problems during construction and it is a common practice, at least in Eastern Europe, in trying to avoid them. The authors studied the influence of three different types of connection details between the masonry panel and r/c tie-columns on the resistance and displacement capacity of confined masonry walls within a scope of the Croatian project "Seismic design of infilled frames". Confining elements around the masonry wall increased stiffness and lateral load capacity. Connection among the masonry wall and ties increased ductile behaviour of the confined masonry. Existing equations for calculation of the lateral strength in EC6 are either under- or over estimating the observed values.
