“…Such structural model can then be coupled with structural engineering tools, such as advanced 3D finite and discrete element methods of analysis (Bui et al, 2017;Giamundo et al, 2014), to assess the robustness and vulnerability of historic structures to extreme natural disasters, e.g. earthquakes, flooding (Sarhosis et al, 2016). In addition, advanced algorithms for automatic detection of structural damages and material degradation in the structure can be developed to assist with the structural health monitoring and assessment of historic structures.…”

ABSTRACT:Cultural heritage structural documentation is of great importance in terms of historical preservation, tourism, educational and spiritual values. Cultural heritage across the world, and in Nepal in particular, is at risk from various natural hazards (e.g. earthquakes, flooding, rainfall etc), poor maintenance and preservation, and even human destruction. This paper evaluates the feasibility of low-cost photogrammetric modelling cultural heritage sites, and explores the practicality of using photogrammetry in Nepal. The full pipeline of 3D modelling for heritage documentation and conservation, including visualisation, reconstruction, and structure analysis, is proposed. In addition, crowdsourcing is discussed as a method of data collection of growing prominence.

“…In the present study, a parametric study was carried out on the influence of friction angle on the pushover response of the columns under investigation. The friction angle between drums varied from 10 to 40 degrees (Dimitri et al 2011, Sarhosis et al 2016. As shown in Figure 14, the friction angle has some influence on the collapse mechanism and ultimate load carrying capacity.…”

“…A comprehensive body of research to investigate the response of rectangular wooden blocks and block assemblies under harmonic and earthquake base excitation was published by Winkler et al (1995). To observe the response of single block and block assemblies, numerical analyses were performed using the Discrete Element Method (DEM) (Dimitri et al 2011, Alexandris et al 2014, Sarhosis et al 2016a. Sarhosis et al 2016b.…”

This paper investigates the nonlinear static behaviour of blocky multi-drum ancient columns. A two-dimensional custom-made computational software based on the Discrete Element Method developed. In the computational model, the columns represented as an assemblage of distinct blocks connected together by zero thickness interfaces, which can open and/or close depending on the magnitude and direction of the stresses applied to them. Through nonlinear static analysis, capacity curves and corresponding failure mechanisms of each of the studied models obtained. The influence of different parameters, namely number of drums, geometrical properties and imperfections at columns, assessed to observe their influence on the response of drum assemblies. The results of analyses revealed that rigid overturning is the main collapse mechanisms under uniform horizontal forces. A combination of rigid and shear failure mechanisms might be obtained depending on geometric characteristics and choice of joint material properties used. Higher displacement capacity observed for columns constructed with larger number of drums. It was found that imperfections at the ancient columns have a significant influence on the lateral load resisting capacity. Therefore, structural analysis of undamaged state of the columns may not represent the actual capacity of the columns due to their very sensitive and highly nonlinear characteristics.

e results of a shake-table study on the effect of the drum height on the seismic behaviour and bearing capacity of small-scale free-standing multidrum columns are presented. Columns of equal height with one, three, and six drums through their height were considered for the case of their self-weight only and for the case with an additional weight on the top of the column. e columns were exposed to a horizontal base acceleration of three accelerograms by successively increasing the maximum acceleration to their failure. e characteristic displacements and accelerations of the column were measured. It was concluded that an increase in the number of blocks in the column can significantly increase or decrease its ultimate bearing capacity, depending on the type of the applied accelerogram. It is expected that the experimental database can be useful in the validation of nonlinear numerical models for the dynamic analysis of multidrum columns.
