Laser scanning is being increasingly applied in the documentation of buildings and archaeological sites. The documentation process sometimes involves making an inventory of bricks in walls. This paper proposes an automatic/semi-automatic segmentation method for detecting bricks in walls, in particular masonry walls. In developing the detection method the problems with detecting bricks in a 3D p...

We deal with the textural aspects, porometry and hydric behaviour of combinations of building materials and their durability under attack by salt crystallisation and freezing. We selected 4 types of lime mortar (pure lime mortar, lime mortar + air-entraining agent, lime mortar + pozzolana and lime mortar + air-entraining agent + pozzolana) which were used in combination with either brick or cal...

the objective of this paper is to present a new method for protecting the lives of residents in catastrophic earthquake failures of unreinforced masonry buildings by introducing some safe rooms within the buildings. the main idea is that occupants can seek refuge within the safe rooms as soon as the earthquake ground motions are felt. the information obtained from the historical ground motions ...

coustructing masonry building has been done in a large scale in our country. a ccording to the recorded statistics. it comprises the majority of building in our country. the loss of life and property as the result previous earthquakes reveals that masonry building have not functioned properly. meanwhile, their complex behaviors resulted from the heterogenons, nonlinear, and plate behavior of it...

Masonry often requires strengthening to withstand against extreme actions such as earthquakes, cyclones and flooding. Recently, new methods have been developed strengthen masonry, fabric reinforced cementitious matrixes fibre polymers. However, other systems welded wire meshing (WWM), reticulatus plastering with matrixes/mortar (CP) also practiced reinforce conversely no systematic design guide...

Microorganisms can be responsible for the destruction of cultural heritage, together with several environmental conditions, ageing and the chemical structure of substrate. There is a number of reviews giving a comprehensive picture of the role of microorganisms in the degradation of art objects, such as paintings, stone, wood, paper, masonry, leather, parchment, glass and metal (Bock and Sand, ...
