| Zusammenfassung |
| Protecting the historical character of a valued structure during the
assessment and damage repair process is a very challenging task for many
engineers. Heritage protection is complicated by a lack of design details
and restrictions on sample extraction needed to obtain accurate material
properties and limited studies on the restoration of certain types of
historical structures. This study aims to assess the effects of soil
settlement on a structure's stress concentrations and the value of laser
scanning techniques on structure analysis in obtaining correct data of
settlement vs. deformation. Terrestrial laser scanner (TLS) data are used to
analyse the 500-year-old historical structure of Naziresha's Mosque. The
obtained TLS data allow an accurate definition of the imperfect geometry
patterns lying on every side of the structure. The soil profile and general
crack formation together with TLS measurement proves that the structure
deformed toward the south façade, where a railway and motorway are also
located. Stress concentration and mode period results have a considerable
difference, which highlights earthquake vulnerability and failure mechanisms
and changes the strategy of possible retrofitting. |
