The demolition process of a historical brick masonry building in St. Petersburg, Russia was observed as a case study and research was conducted on the possibility of reusing the resultant debris, which was composed of high quality brick masonry, as new building material. Therefore, samples from the demolition debris, i.e. brick, mortar and wall pieces were collected and tested for their mechanical properties, according to Russian standards, when available, and according to International Standards for the rest. The results for the compression test of brick and mortar separately as well as wall prisms indicated that their strength was still higher than standard limits, therefore, these wall pieces could be reused under appropriate conditions. Additionally, the bed mortar was tested under shear loads in order to understand if the jointing was still reliable or not. Eurococe 6 (Eurocode 6: Design of masonry structures - Part 1-1: General Rules for Reinforced and Unreinforced Masonry Structures, (2005)) defines a reference table for comparison, which showed that the shear resistance obtained from the wall prisms was also reliable.

This paper presents findings of a comparative study on the removal and disposal of fenestration units in two separate buildings, belonging to the same period and built with similar construction materials. Demolition techniques were used for removing the fenestration units from a building that was undergoing refurbishment; while, deconstruction techniques were used for dismantling similar units from another building that was being selectively demolished.

Masonry structures constitute a significant portion of the building stock in many countries with high seismic regions. Understanding the load carrying mechanisms of such buildings and estimating the deformation capacities is important for seismic risk mitigation. In the process of developing new assessment guidelines for Turkey, a comprehensive research project was conducted in order to estimate the expected seismic performance of existing masonry buildings. Within the scope of this extensive research progr...
A Lower-bound limit analysis solution for lateralload capacity of masonry walls

Masonry exists from very past centuries around the world which is used not only for sheltering, most of historical architectural masterpieces are masonry structures. Masonry offers advantages in many areas such as easy supply of materials, easy to construct and thermal durability of materials. However, the analysis of masonry buildings is not a easy task. Various reasons such as the diversity of materials used and the lack of characteristic properties of these materials, lack of design regulations and the f...
Assessment of the effects of adaptive reuse interventions on three apartment buildings in Beyoğlu, İstiklal street

The main subject of the thesis is the relationship between the new function and the carrying capacity of the building in adaptive reuse interventions in the context of conserving the architectural heritage. In adaptive reuse applications, the first thing that should be considered is that the new function is compatible with the building, in order to ensure that the architectural heritage assets are conserved in a healthy way. Therefore, the purpose of this thesis is to assess the relationship between t...
End-of-life analysis for brick debris: recovery, strength, life cycle cost and environmental assessment

There exists a vast stock of masonry buildings in the world, yet, some of them are being demolished and disposed of; owing to the changes in building bye-laws, redundancies of buildings; and clearing the plots for new and mostly taller buildings. Either demolition or deconstruction is preferred; huge amounts of masonry-based waste are accumulated in the end. On the other end, since these buildings are not always demolished due to wear and tear, the condition of masonry walls after demolition may still be of...
