“…The data include objectively assessed characteristics, such as colour, gloss, chemical composition, and roughness. PLS can also incorporate new sets of specific characteristics and thus estimate the progress of weathering in previously unknown samples (Sandak et al 2015a;b, Sandak et al 2016). This method can predict the degradation level by placing a sample somewhere in between the brand new and completely degraded.…”

“…However, multi-sensor monitoring creates new challenges since different types of sensors are based on different structural features. In this situation, Sandak et al [18] developed a multi-sensor method in timber structural evaluation. With the monitoring data in place, multivariate analysis techniques were considered to assess the performance of the timber structure.…”

“…With the monitoring data in place, multivariate analysis techniques were considered to assess the performance of the timber structure. Sandak et al [18] summarized these multivariate methods, including cluster analysis, identity tests, multiple linear regression, expert systems, neural networks, fuzzy logic, smart algorithms, and so on. Among these methods, an expert system was developed based on fuzzy logic [18,19], which can handle uncertain data and be easily adopted by both experts and non-experts.…”

Structural Monitoring and Safety Assessment during Translocation of Mahavira Hall of Jade Buddha Temple

et al. 2019

The Mahavira Hall of the Jade Buddha Temple in Shanghai, China is a century-old traditional timber structure with a post-and-lintel construction. To improve the temple’s architectural layout and enhance the lintel structural integrity, the Mahavira Hall was moved 30.66 m and then elevated 1.05 m in September 2017. To assist in the structural translocation and uplift, the authors designed a monitoring system to continuously measure the relative displacement and inclination of the overall structure, individual components, and inside statues to ensure the integrity of the hall and its contents. This article presents and summarizes the priority issues and principles of monitoring the ancient Chinese timber structure. The time series of monitored data are decimated in order to minimize the fluctuation of data. The structural integrity of the Mahavira Hall was evaluated based on the inclination angle of its vital members. Finally, combined with the limit value regulated by code and the predicted early warning threshold values, which are based on extreme value theory, the effect of the translocation on the structural performance was obtained using fuzzy logic.
