“…This methodology is adopted for its simplification and reliability when estimating the damage that has occurred for a specified seismicity. Significant advances in the development of fragility curves for heritage structures have been made [35,43,46,51,52,54]. The details of the methodology adapted to generate the fragility curve from the pushover analysis for the heritage bridge structure are described next.…”

The masonry bridges on the Kalka Shimla Mountain Railway line, which have multiple arch galleries in the form of Roman aqueducts, are spectacular. The Kalka Shimla Mountain Railway line is situated in severe seismic zones (Indian Standard 1893:2016). This research assesses the seismic vulnerability of masonry arch Bridge No. 541 situated on the Kalka Shimla Mountain Railway line. This bridge is the tallest on the route. In particular, it assesses the seismic vulnerability of the bridge using finite element (FE) analysis. For this purpose, an FE model for the bridge is developed using the ABAQUS FE-based environment. The experimental field study conducted on the bridge using an ambient vibration test (AVT) and dynamic parameters (frequency and mode shapes) is evaluated by operational modal analysis (OMA). Further, the FE model is updated by modifying the elastic mechanical property of the stone masonry to match the analytical modal frequency with the results of the AVT and OMA. The updated model is then used to perform a pushover analysis and nonlinear dynamic analysis to estimate the seismic performance of the bridge. Furthermore, fragility curves are developed for the bridge to estimate the damage state for specific seismicity. The study shows that the bridge is vulnerable to Zone IV seismicity and needs some retrofitting in specific locations such as the pier–abutment joints.

Heritage structures are valuable monuments to describe the culture and traditions of the country. These heritage structures get deformed in today's scenario by natural or artificial disasters. Hence, to preserve these heritage structures, restoration was introduced to restore the ancient building with new binding agents. Rehabilitation can take place only by analysing the properties of existing structures. Based on the existing structure properties, the alternative binding agent selected; can regain the same strength and shape of the heritage structures. Based on these, the restoration of Alamparai fort was performed by analysing the fort materials using mortar strength analysis by core-drilling, double punch test, and small-scale masonry test. The arch properties are also analysed by performing seismic analysis based on the mortar strength properties. The stability analysis of the organic and existing materials shows that Gur and haritaki is the best agent for restoring the fort. Hence, the mortar strength and seismic analysis of these materials performed using diagonal shear test and seismic modelling of the fort. The proposed material strength tests results indicate that the Gur and Haritaki is the best agent to restore the fort. The fort was restored with these materials; it survived in Nivar cyclone crossed on 26th November 2020.

Ancient structures were constructed by considering only vertical static loads. The seismic response of ancient masonry structures depends on their material properties, the geometry of the structure, the types of connections between various structural components, the stiffness of the floors and the strength of the non-structural elements. The rich and diverse architectural traditions across India provide evidence of the structural efficiency and technological skill of Indian craftsmen and builders. Studying the structural behaviour of Indian heritage buildings has national importance. In this study, the seismic vulnerability of the Amritesvara temple was evaluated. Built in 1196 and is located 260.8 km from Bengaluru, India. This study involved a shake table test of the temple. Experiments were conducted at the Earthquake and Vibration Research Centre, Bengaluru. According to the size and payload capacity of the shaking table, a 1:3 scale model was adopted. The model was subjected to various peak ground accelerations from 0.05 to 0.1 g. The dynamic properties of the model were evaluated through the experiments. The experimental results were used for validating the numerical model, which was used to conduct further investigations on the prototype.
