Figure 7: The precision measurement of the deformation of the outer walls [1] showed

that the disorders are perfectly symmetric between the north and south sides, but not

symmetric between the east and west sides, probably due to the effects on the domeof

the dominant wind from west.

Figure 8: On the left: a non linear finite element model (ABAQUS)of the two outer

domes. Onthe right: a distinct element model (UDEC)for the analysis of fractures in

the great arches and in the outer walls [1].
