Complex  masonry  monuments  represent  an  important  part  of  the  built  cultural 

heritage  and  most  of  them  are  vulnerable  to  seismic  actions.  Their  large  scale,  irregularity, 

and heterogeneity makes it challenging to characterize their structural behaviour. 

This  work  addresses  the  state  of  conservation  as  well  as  the  structural  behaviour  and 

seismic  vulnerability  of  the  most  ancient  body  of  the  National  Palace  of  Sintra,  Portugal: 

the  Bonet building.  This  body  was  built  on  top  of  Arabic  foundations  during  the  reign  of 

King  Dinis, around the year 1281, and since then few alterations were made to the building.  

In  order  to  minimize  the  multiple  uncertainties  usually  existing  in  complex  masonry 

buildings, whether related to geometry or masonry mechanical properties, a detailed structural 

survey was conducted together with different in-situ experimental tests. All the tests 

performed  were important to the adequate characterization of the building and the 

calibration  of  the  numerical  models.  The  final  values  adopted  for  the  mechanical  properties 

of the rubble stone masonry are presented and can be used as  a reference for future works in 

ancient Portuguese monuments of the same period. 

Afterwards,  nonlinear  static  analyses  were  performed  in  two  different  software  (3MURI 

and  ABAQUS).  Comparisons  and  discussion  of  the  results  are  made.  The  differences  in 

modelling strategies and characterization of materials between the two software are considered 

with  regard  to  their  realism,  computational  effort,  data  availability  and  applicability  to  large 

scale structures. Efforts  to  calibrate  and  obtain  the  same  behaviour  of  the  building  for  the 

different software were made, involving geometry, boundary conditions and 

characterization  of  the  material constitutive laws.
