FRAmed-MAsonry composites for modelling and standardization (FRAMA) In r-c frames infilled with masonry (framed-masonry) the infill walls stiffen the frame and reduce the first-mode period leading to a reduction in drift response to strong ground motion. At the same time, the addition of the masonry w all to the frame tends to increase the base-shear response and reduce the drift capacity of the structure. The increase of lateral force and reduction of drift capacity leads to serious vulnerabilities unless proper proportioning is exercised. For frames with competent walls, the challenge for safe and economical design is to be able to take advantage of the stiffening but to make certain that the increase in lateral forces and reduction in drift capacity do not handicap performance. Available evidence has pointed out that shear strength of the confining column is the ”Achilles’s heel” of the system. Solution of the problem requires understanding the behaviour of masonry and concrete subjected to dynamic and random loading reversals, a challenge that demands testing under reasonably realistic conditions for confident analysis of the problem and its generalization. This is a proposal to investigate the safety and behaviour of buildings with masonry infilled r-c frames through near full-scale dynamic earthquake simulation tests accompanied by supporting pseudo-dynamic tests of structural assemblies and components and by calibrated analytical solutions. The overall goal is to develop pragmatic methods, by cooperative efforts of team members and co-working international body, for design, safety evaluation and standardization. Because framed-masonry serve both architectural and structural demands efficiently, people in seismic regions live and will continue to live in buildings of this type. An organized solution of the safety of such construction is essential. This proposal intends to put the ”framed-masonry” composite up as a full-fledged building type.
