“…In the following decades several other nonlinear models were developed and some of them are already available to practitioners and make now possible to carry out reliable nonlinear pushover analysis of masonry structures [3] [4]. These methods, generally based on the equivalent frame approach [5][6] [7] and the macro-element discretization (single 2-node elements modeling structural members such as piers and spandrel beams), require a limited computational burden since the number of degrees of freedom and elements in the structural model is limited.…”

“…These elements are connected by rigid offsets and modelled by proper constitutive laws in order to take into account the mechanical nonlinearity (Dolce, 1989). Several studies have been done by different researchers; (Lagomarsino et al, 2006;Gambarotta and Lagomarsino, 1997;Penelis, 2006;Calderini and Lagomarsino, 2008;Belmouden, 2009). In these approaches, a nonlinear macro-element model, able to reproduce earthquake damage to masonry structures and failure modes observed during experimental testing, has been implemented with similar approximations.…”

Abstract. This study evaluates seismic capacity of the unreinforced masonry buildings with the selected template designs constructed per pre-modern code in Albania considering nonlinear behaviour of masonry. Three residential buildings with template designs were selected to represent an important percentage of residential buildings in medium-size cities located in seismic regions of Albania. Selection of template designed buildings and material properties were based on archive and site survey in several cities of Albania. Capacity curves of investigated buildings were determined by pushover analyses conducted in two principal directions. The seismic performances of these buildings have been determined for various earthquake levels. Seismic capacity evaluation was carried out in accordance with FEMA (Federal Emergency Management Agency) 440 guidelines. Reasons for building damages in past earthquakes are examined using the results of capacity assessment of investigated buildings. It is concluded that of the residential buildings with the template design, with the exception of one, are far from satisfying required performance criteria. Furthermore, deficiencies and possible solutions to improve the capacity of investigated buildings are discussed.

In this paper a novel equivalent planar-frame model with openings is presented. The model deals with seismic analysis using the Pushover method for masonry and reinforced concrete buildings. Each wall with openings can be decomposed into parallel structural walls made of an assemblage of piers and a portion of spandrels. As formulated, the structural model undergoes inelastic flexural as well as inelastic shear deformations. The mathematical model is based on the smeared cracks and distributed plasticity approach. Both zero moment location shifting in piers and spandrels can be evaluated. The constitutive laws are modelled as bilinear curves in flexure and in shear. A biaxial interaction rule for both axial force -bending moment and axial force -shear force are considered. The model can support any shape of failure criteria. An event-to-event strategy is used to solve the nonlinear problem. Two applications are used to show the ability of the model to study both reinforced concrete and unreinforced masonry structures. Relevant findings are compared to analytical results from experimental, simplified models and finite element models such as Drain3DX and the ETABS finite element package.
