Drift-sensitive non-structural damage to masonry-infilled reinforced concrete frames designed to Eurocode 8

Fragility functions for masonry infill walls with in‐plane loading

“…Most of current seismic codes are force‐based and, therefore, primarily rely on checking that structural elements have sufficient strength and give secondary importance to lateral deformations and to the performance of nonstructural components . For this reason, although an important body of work has addressed the assessment of the strength of masonry infill walls and their influence on building response, very few studies have been devoted to estimating the progression of in‐plane damage as a function of lateral deformations being imposed on them (see, eg, Ricci et al).…”

Seismic Vulnerability Assessment: Reinforced Concrete Structures

“…On the other hand, experimental tests (e.g., Mehrabi et al 1996;Colangelo 2003) and postearthquake damage observations (e.g., Ricci et al 2011;De Luca et al 2014b;Manfredi et al 2014) have shown that this kind of elements can have a significant impact on both damage and loss analysis of RC structures, especially in the Mediterranean area, in which this kind of structural typology is quite common. Notwithstanding the fact that damage observations based on experimental tests are available in literature and macro-modeling approaches and component modeling backbones as well are available in literature, still characteristic parameters for infill fragilities are characterized by significant differences according to different authors (e.g., Gu and Lu 2005;Özcebe et al 2012;Colangelo 2013). The point is that in the case of damage analysis of infills, authors do not even agree on damage states' qualitative definitions.…”

“…and the feasibility of repair. As an example, Table 4 provides damage description at different damage states according to different authors; see Colangelo (2013). Significant differences can be found in damage descriptions and, as consequences, also in the fragility function parameters estimated from each description (see also Colangelo 2013).…”

“…In particular, behavior of RC elements and their modeling still requires significant experimental and numerical efforts. Behavior of non-ductile RC elements (e.g., characterization of axial load failure) should be better characterized on the basis of higher number of experimental tests in order to better characterize Table 4 Damage state definition for masonry infills according to Colangelo (2013) Damage state Damage description (Colangelo 2013) Damage description (Gu and Lu 2005) Damage description (Özcebe et al 2012 both modeling issues and damage analysis issues in terms of median and logarithmic standard deviation. Same considerations can be made on beam-column joints and masonry infills.…”

Drift-Based Fragility Assessment of Masonry Infills

“…Most of current seismic codes are force-based and therefore primarily rely on checking on the strength of structural elements giving a secondary importance to lateral deformations [18]. As a consequence, that there is an important body of work addressing the assessment of the strength of masonry infill walls and their influence on building response, whereas very few studies have been finalized to estimating damage evolution based on imposed lateral deformations (see e.g.…”
