STRUCTURAL MODEL VERIFICATION OF WAT CHINORASARAM WORAWIHAN PAGODA

Abstract

          The objectives of this research article were to proposes the guideline to develop the structural engineering assessment model for the historical monument renovation. In addition, the verification process of the finite element model of Wat Chinorasaram Worawihan Pagoda was applied to this research. There are various levels of detail for developing the finite element model of structure, which was depending on the assumptions and limitations of the computer software. The model with highly details may cause unnecessary effort to the modeler and structural analyzing processes. In contrast, the model with low level of details may lead to inaccurate results. This research showed the comparison of analyzed results from different levels of model’s precision as recommended in the guideline for the development and analysis of structural models. Investigation processes were performed by comparing the results obtained from 3 structural models with difference level of details. The based model with the highest level of details (HDM), the Simplified Detail model (SDM) created from boundary volume of the HDM, and the Low detail model created from rod-elements which compact all geometrical details into cross-sectional area and mass (LDM). After perform stress analysis of all three models, the relations between stress and elevations of the structure were constructed. This study found that using results from a multi-level of details can suggest the reference boundary for investigating the validity of the based model. LDM was provided the lower bound stress at -6% and SDM was provided upper bound stress at 17%. The systematic processes of creating boundary volume need more future investigation.
