“…These characterisations can be considered consistent with those reported in Kappos and Panagopoulos [24]. In particular, old code types can be considered consistent with low code and Moderate code in Kappos and Panagopoulos [24].…”

In seismic risk mitigation policies, fragility functions of existing buildings play a fundamental role. In this paper, a procedure to develop analytical fragility curves for Moment Resisting Frame Reinforced Concrete buildings is presented. The design of the selected building typologies was performed according to the codes at the time of construction using force-based methods and the state\ud of the practice at the time of construction. A total of 216 building classes were defined, considering different ages, number of storeys, infill panels, plan dimensions, beam stiffness, and concrete strength. The investigated buildings can be considered low-engineered buildings, using no seismic codes or old seismic codes. The seismic capacity of the selected models representing the existing RC buildings has been evaluated through non-linear dynamic simulations. Seismic response has been analyzed, considering various peak and integral intensity measures and various response parameters, such as ductility demands and Interstorey Drift Ratio (IDR). A new relationship among structural performance, damage levels and interstorey drift ratios for each studied type is introduced, which is calibrated using the damage levels described in EMS98. It is important to highlight that in this study, different thresholds of IDR have been associated with different typologies, considering their different ductility member levels after their different structural responses. Fragility Curves (FCs) for the studied structural types are set up, developed and discussed

This paper analyzes the seismic vulnerability of vernacular Newari buildings in Nepal. Based on the damage statistics and failure modes recorded during 1934, 1988, 2011, and 2015 earthquakes, damage probability matrices and seismic fragility functions are derived in this paper. Notable seismic features of the Newari buildings are identified and reported using forensic approach. The result of this study highlights that the vernacular Newari buildings are highly vulnerable in the case of minor to major earthquakes; however, the seismic features have contributed to downscale the damage extent.

Abstract. This paper reports the seismic vulnerability of vernacular Newari buildings based on the damage observations during four major earthquakes (1934, 1988, 2011 and 2015) that struck Bhaktapur city. Some specific features that contributed to 10 collapse prevention in traditional masonry buildings are also highlighted in this paper. In this paper, we have outlined the insights of each earthquake using forensic interpretations and the recommendations by various researchers after 1934 and 1988 earthquakes are compared in terms of their implementation. With the help of damage database recorded during 1934, 1988 and 2015 earthquakes, we have created damage probability matrices and empirical fragility functions for traditional masonry structures. The fragility functions and damage probability matrices derived in this study highlight that most of the vernacular 15Newari buildings are likely to be collapsed in the case of strong to major earthquakes.
