“…However, beyond the initiation of cracking, linear elastic analysis fails to adequately represent the structural behaviour, especially in historical masonry. The inferences from the present investigation on mandapam are in line with the conclusions of similar studies in the literature [12,14,15,36]. Some of the salient inferences can be enumerated as follows.…”

“…• The current study, like others in the literature e.g., [15], suggests that FE approach for modelling the seismic response of dry historical masonry structures may not be appropriate, and results from FE approach can be misleading unless they are properly interpreted. This could be an effective tool if FE models are validated with appropriate field testing for dynamic identification.…”

“…Subsequently, the E value was reduced to around 1/10 th its original, in order to match ambient vibration test results, suggesting FE continuum modelling for dry masonry is not appropriate. Researchers have come to similar conclusions on FE modelling of dry masonry towers in Bayon temple, Cambodia [15].…”

The gopuram (multi-tiered entrance gateway) and the mandapam (pillared multipurpose hall) are two representative structural forms of South Indian temples. Modelling and seismic analysis of a typical 9-tier gopuram and, 4-and 16-pillared mandapam of the 16th century AD Ekambareswar Temple in Kancheepuram, South India, are discussed. The seismic input is based on a probabilistic seismic hazard analysis of the archaeological site. Two modelling strategies, namely lumped plasticity and distributed plasticity modelling, and three analysis approaches, namely linear dynamic, non-linear, static and dynamic analyses were adopted for the seismic assessment of the gopuram. Unlike slender masonry towers, the vulnerable part of the gopuram could be at the upper levels, which is attributable to higher mode effects, and reduction in cross section and axial stresses. Finite element and limit analysis approaches were adopted for the assessment of the mandapam. Potential collapse mechanisms were identified, and the governing collapse of lateral load, calculated based on limit theory, was compared with the seismic demand as a safety check. Simple relations, as a means of rapid preliminary seismic assessment, are proposed for the mandapam.

“…The strengthening materials that were used at the time have deteriorated, however, such that it has become necessary to consider conducting a re-restoration. Behavior measurements and structural analyses of the masonry of the central tower that have been conducted by JSA/JASA so far show no signs leading to the collapse of the tower [1][2][3][4]. In addition, based on the structural analysis of the central group of Towers of Bayon, there is little risk of these collapsing immediately [5][6][7].…”

Bayon temple, built in the latter half of the 12th century, is one representative temple of the Angkor monuments. To shed light on the foundation structure of the central towers that stand on the elevated terrace, archaeological excavation and boring tests were conducted. Based on these surveys, a unique foundation structure was revealed under the central towers. It was confirmed that there is no laterite or sandstone support structure directly beneath the upper structure, and that there is only compacted soil at a thickness of approximately 16 m above the natural sedimentary soil. On the other hand, a laterite masonry 6 m thick and 7–9 m wide was confirmed from around the compacted soil. In other words, the heavy load of the central towers is supported by compacted soil that is constrained from the sides by a laterite structure. In addition, the boring surveys provided new insights into the low structural property of the backfilled soil after the past excavation survey below the central tower and the extension process of the elevated terrace supporting the central towers. Delivered information about the foundation structure and material of central towers, including soil property, water table, water contents, and bearing capacity will be valuable for the future structural assessment of this temple.

“…Researchers have conducted many studies to analyze the vibrations of historic buildings . The dynamic characteristics of structures have been measured using field tests based on the ambient vibration exactions [1,2,5]; the identified modal parameters were then used to update the finite element (FE) model of the target structure [8,[13][14][15]21], which was in turn used to develop the prediction methods. Breccolotti et al [10] established a methodology for predicting the vibration levels induced by railway traffic.…”

A prediction method in the frequency domain is proposed for predicting the vibrations of historical timber building induced by traffic loads. The modal parameters of a structure are identified using a double-confirmation analysis method based on the autospectrum. Then, the vibration responses of the building are calculated using a limited number of measurement records by inputting the calculated vibration information for the foundation of the updated building model. The proposed method is used to predict the vibrations of the Buddhist sutra depositary at Yangzhou Zhunti Temple. Comparing the results shows that the vibration responses of a structure under traffic loads can be effectively predicted in the relevant frequency bands.
