This research focuses on the wall and the towers of the Great Wall of China in Jinshanling, located in Luanping County, approximately 153 km northeast of Beijing, China. The study reveals that the main construction methods used to create the wall were rammed earth and rubble construction, foundation stone masonry installation, and mostly Flemish configuration brick masonry installation. These methods were implemented in a bottom-up construction. In some areas, especially in the eastern area of Jinshanling, foundation stones and bricks were integrated with existing stone masonry (large stones and mortar) from an earlier construction period at the beginning of the Ming Dynasty. The main construction method used to construct the towers was also rammed earth and rubble construction for the base of the tower’s inner core of the base. Similarly, to the wall, the towers were completed with an outer layer at the base composed of fire kiln bricks and foundation stones. The installation of fire kiln brick masonry and foundation stone masonry were implemented on the outer layer of the towers’ base. The main difference between the towers is the support system on the first floor. One design used timber columns on the first floor to support the second floor of the towers, while a second design used interior brick walls, arches, and vaults on the first floor to support the second floor. There is a statistical correlation showing that the bricks and arches supporting the towers were more likely to be implemented at a higher elevation in sampled towers. The findings from literature searches, site visits, and interviews of experts on the Great Wall were used as the inputs for the fuzzy sets and logic assessments. The fuzzy models used in the evaluations were the fuzzy sets angular model and the fuzzy sets rotational model. The outputs of the fuzzy evaluations (i.e., the main construction method, the sequence implemented at the time of construction, and the current performance of the structure) were used as the inputs to create the VR model of the structure using the software SolidWorks, Google SketchUp (with Google Earth), Unity Pro, and 3ds Max. This virtual reality model guided the end user through the construction methods of the structure (dynamic interaction) and gave a walkthrough simulation of the structure. The acquisition and analysis of the knowledge base from the literature review, site visits, and interviews of the experts are shown in Volume I of this dissertation. The fuzzy assessments are presented in Volume II, and the creation and feedback of the VR models are shown in Volume III of this dissertation.
