“…Regarding current research in the field of earthquake resistance of architectural heritage, stress response and the damage mechanism of architectural heritage during earthquakes have been analyzed by theoretical model establishment and software simulation, experimental tests, monitoring data feedback and other methods, and then measures of seismic performance improvement have been given or seismic guiding principles proposed. In the aspect of theoretical model establishment, existing research into the mechanics of various materials and structural mechanics have been mainly used as references, and an improved theory of mechanics or models have also been adopted as research support [1][2][3][4][5], the simulation analysis tools mainly used are finite element analysis (FEA) software such as ANSYS [6][7][8][9][10], 3Muri [11][12][13], ABAQUS [14,15], SATATS [16], BrickWORK [17], TREMURI [18], etc. ; from the aspect of experimental testing, earthquake response characteristics have usually been obtained by the shaking table test [19] and ambient vibration tests [20][21][22], the intensity index is mainly detected by the triaxial compression test [23]; from the aspect of data monitoring, data obtained by monitoring tend to be used for structural safety assessments and structural strength improvement [24][25][26][27]; at the time of studying earthquake damage mechanisms, there have been macroscopic assessments for architectural heritage for some materials or structures [28][29][30][31][32], and in-depth assessments on architectural heritage monomers [33][34]…”

A lot of architectural heritage in China are urgently in need to carry out seismic assessment for further conservation. In this paper, a seismic capacity evaluation approach for architectural heritage using finite element analysis with precision three-dimensional data was proposed. The Limestone Hall of Shaanxi Province was taken as an example. First, low attitude unmanned aerial vehicle photogrammetry and a close-range photogrammetry camera were used to collect multiple view images to obtain the precision three-dimensional current model of the Limestone. Second, the dimensions of internal structures of Limestone Hall are obtained by means of structural analysis; re-establishing the ideal model of Limestone Hall based on the modeling software. Third, a finite element analysis was conducted to find out the natural frequency and seismic stress in various conditions with the 3D model using ANSYS software. Finally, the seismic capacity analysis results were comprehensively evaluated for the risk assessment and simulation. The results showed that for architectural heritage with a multilayer structure, utilizing photogrammetric surveying and mapping, 3D software modeling, finite element software simulation, and seismic evaluation for simulation was feasible where the precision of the modeling and parameters determine the accuracy of the simulation. The precise degree of the three-dimensional model, the accurate degree of parameter measurement and estimation, the setting of component attributes in the finite element model and the strategy of finite element analysis have an important effect on the result of seismic assessment. The main body structure of the Limestone Hall could resist an VII-degree earthquake at most, and the ridge of the second floor could not resist a V-degree earthquake due to unsupported conditions. The maximum deformation of the Limestone Hall during the earthquake occurred in the tabia layer below the second roof.

“…These in turn support the final floor finish. This technique closely resembles to the ancient masonry buildings floor structure construction practice throughout Europe [110]. Given that Nepal is located in an earthquake prone zone, some carpenters have developed their construction techniques accordingly, providing additional bracing by linking the vertical and horizontal structural components [111].…”

Existing slender masonry structures, such as Pagoda temples, towers, minarets and chimneys, exist all over the world and constitute a relevant part of the architectural and cultural heritage of humanity. Their protection against earthquakes is a topic of great concern among the earthquake engineering research community. This concern mainly arises from the strong damage or complete loss suffered by these types of structures when subjected to earthquake and also from the need and interest to preserve them. This chapter firstly presents a methodology for assessing the seismic vulnerability of slender masonry structures based on vulnerability index evaluation method. Secondly, presents the correlation between vulnerability index and Macroseismic method to estimate the physical damage in relationship with seismic intensity. Finally, presents implementation of the methodology to construct vulnerability curves, fragility curves and estimate losses.
