It is important to predict the future behavior of historic buildings to avoid potential problems. Wat Khao Sukim Pagoda is situated on a hill slope and has different types of foundations. These foundations include both shallow and pile foundations representing different stages of construction and having different loadings. Although the structure meets the design criteria for the current loading, in the future overloading may occur. Therefore, an analysis of additional loading was undertaken using the 3D finite element method (FEM). In particular, the effects of differential settlement and its mitigation were investigated. Changes in the groundwater level were simulated after major rain events and compared to dry conditions. Overall, the concept of staged construction (preloading) is a useful technique to minimize the risk of differential settlement associated with different types of foundations. In addition, the current results showed that the average differential settlement value at each stage was lower than in previous work. Furthermore, the new model reduced the differential settlement value by more than 50%. These results showed that the concept of preloading can better solve the differential settlement problem in this type of construction. The PLAXIS 3D model showed that the groundwater level increase did not affect Pagoda settlement, indicating that the Pagoda was stable and could withstand a large load without undergoing any major structural deformations and that it was suitable structurally for a variety of applications, even in wet conditions.

“…In most cases, only a limited amount of data is available. For that reason, the stratigraphy must be simplified during the modeling process [10]. Indeed, it is common to overlook relatively thin or discontinuous layers, which can be corrected with proper parameter calibration based on monitoring data or field observation [11].…”

This paper presents a three-dimensional foundation numerical model of Thailand's historical building, the Wat Khao Sukim Pagoda. The Pagoda's high reputation is due to the fact that it was constructed through donations from the public. The purpose of the research is to analysis the differential settlement and define the capable layer to transmit the load from structure. Numerical analysis will significantly contribute to the construction and mitigate the impact of any potential differential settlement. The present study is using PLAXIS 3D to model the ground surface and to analyze the settlement of the complex foundations of the Pagoda, which is loaded by varying column load. Back-analysis of the single pile load test was performed to verify the soil parameters and the results of the numerical simulations were in good agreement with settlement data reported in the field. The numerical analysis showed the settlement values in Zone 1 (shallow foundation) were in the range 0.05-0.43 mm, in Zone 2 (short pile foundation) were in the range 0.42-1.98 mm, while Zone 3 (long pile foundation) had a settlement range of 0.82-1.25 mm. These results were considered acceptable due to the modes differences in values that the differential settlement did not exceed 0.75 ins or 19 mm as recommended by ACI, 2017 and ASCE/SEI 7-02, 2013. Also, Weathered Granite layer is determined as an effective layer capable of transmitting a significant load of higher than 50%.

Original scientific paperIn existing buildings, it may be necessary to repair, adapt, renew, relocate or demolish buildings and building parts that have come to the end of their usage period due to spatial, functional, technical and economic obsolescence. After the necessary applications to extend the service life of buildings, it is of great importance to analyze the dynamic behavior of buildings under soil-structure interaction and earthquake loads and to obtain accurate results. In this study, the seismic soil-structure interaction of the historical Sungur Bey Mosque, which was first built in 1577 but was disassembled, moved and rebuilt in another area (relocated) in order to preserve its historical and cultural values and extend its service life, was examined. The analysis of the masonry structure that survived after the Sivrice (2020) earthquake, where the great loss of life and property occurred, was carried out with the PLAXIS 3D software program. The real record of the Sivrice NS (2020) earthquake was used in dynamic analysis. Local soil properties obtained as a result of field investigation studies were utilized in numerical modeling. Depending on the result of the analyzes, the effects of soil-structure interaction on a reconstructed historical masonry structure were examined. The results obtained from the analysis showed that the local soil conditions have an amplification effect on seismic waves that may induce structural damages in prospective seismic events.
