“…Existing literature on the numerical analysis of heritage structures by non-linear analyses documents well the complexity of the task and the uncertainties which remain unresolved in the interpretation of the seismic behavior of heritage masonry structures (see for e.g., [13][14][15][16][17]). The knowledge of structural features of heritage buildings, as well as of the material properties to be used in the safety assessment and retrofitting of existing structures, represents another complex task for engineers due to limitations arising from lack of destructive tests in heritage constructions [18,19]. Historical structures represent a particular time frame and the exact material properties and degradation cannot be adequately modeled.…”

The so-called Greco-Roman monuments, also known as neoclassical monuments, in Nepal represent unique construction systems. Although they are not native to Nepal, they are icons of the early 19th century in the Kathmandu valley. As such structures are located within the heritage sites and historical centers, preservation of Greco-Roman monuments is necessary. Since many buildings are in operation and accommodate public and critical functions, their seismic safety has gained attention in recent times, especially after the Gorkha earthquake. This paper first presents the background of the Bagh Durbar monument, reports the damage observations, and depicts some repair and retrofitting solutions. Attention is paid to the implementation of the different phases of the structural characterization of the building, the definition of reference material parameters, and finally, the structural analysis made by using finite element models. The aim of the contribution consists of comparison of the adequacy of the finite element model with the field observations and design of retrofitting solutions to assure adequate seismic safety for typical Greco-Roman buildings in Nepal. Thus, this paper sets out to provide rational strengthening solutions compatible with the existing guidelines rather than complex numerical analyses.
