“…In the last few decades, many researches have been conducted to investigate the efficient measures to mitigate the risk of earthquakes on buildings. Regarding to masonry buildings, the attention was relatively low with prime focus on historical buildings [1][2][3][4][5][6][7][8]. Investigations showed that the building is susceptible to heavy damages and collapse when subjected to the specified moderate to high seismic intensities.…”

Masonry buildings in seismic active regions experienced severe damages and collapses during earthquakes. Many researches were published concerning the seismic assessment of masonry buildings. Almost, all previous studies focused on historical buildings located in different regions in the world. This paper evaluates the seismic performance of ordinary residential masonry buildings located in three different regions in Iraq with various seismic intensities. Masonry buildings included houses, public and commercial buildings are common construction practice in Iraq. A three dimensional finite element modeling was adopted for the investigations in which nonlinear static pushover analyses were conducted to derive capacity curves of the building models. The finite element model was verified against experimental results presented in the literature. Capacity curves were compared with seismic capacity demands derived for each building model in both perpendicular principle axes. Two house building models with semi-regular and irregular plan layouts were considered in the investigations. The influence of the strength of the local clay bricks and the quality of the mortar on the seismic performance of the buildings was considered. Investigations have demonstrated that the plan layout and the strength of bricks and mortar are significantly influencing the seismic performance of the considered masonry buildings. For the considered models, the base shear capacity of the semi-regular house and that for the irregular house model have increased up to 233 % and 100 %, respectively by increasing strength of clay bricks from 9 MPa to 18 MPa. Using cement sand mortar with a compressive strength of 15.2 MPa rather than lime mortar that have compressive strength equal to 3.1 MPa contributes in increasing building shear capacity up to 20 %. Seismic vulnerability of masonry buildings in the considered cities with low to medium seismic intensities could be averted by using relatively high strength mortar and brick as well as adopting regular plans.

“…The diversity of modelling needs has driven to the development of several approaches with different levels of detail regarding the material discretization (Roca et al 2010). Finite Elements (FE) continuum macro-mechanical modelling approaches are commonly adopted to address simplified and practice-oriented simulations of masonry walls subjected to in-plane and out-of-plane actions (Saloustros et al 2017b;Saloustros, Cervera, and Pelà 2019;Pantò et al 2019;Kouris and Kappos 2012;D'Ambra, Lignola, and Prota 2016;Endo et al 2015;Bilgin and Korini 2014;Spyrakos and Francioso 2012). Macro-models do not make any distinction between units and mortar joints, and masonry is represented as a continuous homogeneous material in a simplified manner.…”

Existing heritage buildings are often composed of diverse materials and structural typologies, representing a challenge for structural analysis tasks. This work investigates the combined use of simple Lumped Plasticity Models (LPM) and macro-mechanical Finite Element (FE) approaches to evaluate the seismic response of structures composed of timber frames and masonry walls. The calibration of these engineering models is derived from a wide set of nonlinear static analyses reproducing benchmark experiments on timber and masonry specimens. The LPM and FE models are used eventually to appraise the seismic response of two existing timber-masonry hybrid buildings, located in the historical centre of Valparaíso, Chile. The nonlinear analyses performed with these models predict the accelerationdisplacement capacity of the buildings under seismic-like horizontal loading, revealing their potential local and global failure mechanisms.

“…Particularly, Bilgin and Huta 2018, [1] have shown that the URM is the dominant building typology of the country for both public and private buildings during the socialist era . Most of these current masonry buildings were designed considering merely gravity loads without any consideration of earthquake resistant design rules [2]. Furthermore, previous studies [3][4][5][6][7][8][9][10][11] and earthquake inspection reports have shown that masonry structures are very susceptible to seismic movements.…”

Recent earthquakes occurred in many parts of the world have shown that unreinforced masonry [URM] buildings constructed according to older codes may constitute an important source of risk. It is known that the mechanical response of the masonry structures depends on several factors including the compressive and shear strength of its constituents, bricks shape as well as the volumetric ratio between the wall texture and components. In this study, the effects of the material choices of a particular type of masonry buildings were studied. The typology chosen in this study represents a typified masonry building of the current Albanian building stock; these buildings were mostly built between 1977-78 and thus were designed without considering the seismic requirements proposed in today's modern codes. This template building has been constructed in different regions of the country with the same architectural and structural configuration in two versions; red clay bricks and silicate bricks. The aim of this study is to investigate the influence of these two different materials on the seismic response of the selected masonry building. The evaluation is based on the use of nonlinear static analyses, performed by using TREMURI software. In order to estimate the reliable seismic response for this typology, extensive research in terms of historical information, structural characterization and the definition of the inherent material parameters has been executed. Upon the evaluation of the obtained results, in contrast to the type of buildings constructed by clay masonry, calcium silicate one showed a stiffer and slightly stronger response. However, at similar values of in-plane, lateral drift they exhibited more brittle response yielding unforeseen damage during seismic excitations.
