A new Greek Code is already approved and in force, covering structural assessment, interventions (repair or/and strengthening) and redesign of existing reinforced concrete (RC) structures, in line with the relevant provisions of Euro-Codes, and especially of EC 8-1 : 2004 and of EC 8-3 : 2005(for new and existing structures, respectively). Among the various aspects covered by this extensive Code, admittedly far beyond and more detailed than EC 8, is that of masonry partitioning-infilling walls (made mainly of perforated clay bricks), already existing (plain/unreinforced-URM, with one or two leafs-wythes, previously damaged or not) or enhanced or arranged on purpose for seismic upgrading of old or/and inadequate RC buildings, consisting of engineered masonry panels, unreinforced or even reinforced. According to this newGreek Code (nGCI), a lot of additional (to those of the EC 8) related problems and aspects are at least shortly covered (in a code-like format) and presented/discussed in this paper, such as : Basic principles, i.e. reliability aspects, interaction of URM infills and RC elements or structures, quantitative global and local influence for frames or quasi-frames, possibly adverse local effects, assessment, repair or/and strengthening; Technological and geometrical aspects, i.e. types of infills, existing (non-engineered) or new, geometrical data, presence of one or of two leafs (connected or not), panel's thickness and slenderness, influence of openings and of wedging; Mechanical behavior, i.e. out-of-plane and in-plane response, macro-models based on shear panels or onequivalent com- pression diagonals (struts), mechanical characteristics and typical (default) mean values for design and redesign, influence of past damage and residual characteristics, as well as Methods of analysis, assessment and redesign, i.e. linear and non-linear approaches, static or dynamic ones,verifications in terms of force (global or local behavior factors) or displacement, based on specific performance requirements and levels (no-collapse, significant damage, limited damage). The rationalism, the methodology and the application rules of this new Greek Code on (Structural) Interventions (nGCI) are expected to influence EC 8 as well as the provisions for seismic design of even new framed or quasi-framed common RC structures of low to medium height (i.e. up to max. 10 storeys).
