The harsh environmental conditions, especially during the winter, resulted in the accelerated decay of the building materials, material losses, and serious structural problems in the Baths. This study explores the comprehensive characterization and multiscale assessment of bricks and mortars for effective preservation of the Baths. Experimental results showed that although the interface between building materials weakened after years of accumulated degradation, the individual materials still had higher strength than those from the same period. The material scale finite element model used to understand the damage mechanism showed that brick failure was caused by the tensile stresses accumulated at the brick–mortar interface when some of the mortar crumbled and fell with deterioration. A global sensitivity analysis was also conducted to investigate the impact of individual layer thicknesses on the stress distribution in the brick and mortar composite. Results indicated that thicker bricks resulted in better confinement at mortar layer and smaller tensile stresses at the bricks.

Analysis on the mechanical properties of historical brick masonry after machinery demolition Ucer, Deniz; Ulybin, Aleksey; Zubkov, Sergey; Elias Özkan, Soofia Tahira (2018-02-10) 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 re...
An experimental study on geotextile-soil filter system Gül, Sevil; Huvaj Sarıhan, Nejan; Department of Civil Engineering (2020-10-21) Filters have been used in earth structures such as retaining walls, earth dams etc. to prevent the loss of particles induced by seepage of water. Traditionally granular filter materials are used, however, they are becoming more difficult to obtain and transport to the construction site and transportation of granular material raise the cost of construction and carbon footprint of the project. Therefore, the need for an alternative filter material arises, and geotextiles can be considered as one of the best o...
The Impact of surface texture and wind on convective heat transfer from building façades Öztürel, Necil; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2013) In this study, the impact of the surface texture of finishing materials and wind conditions on heat loss from the building’s facade are investigated. Three sets of samples (Set A, B and C) are tested and observed under varying wind speeds and varying wind angles in a wind tunnel. Both Sets A and B are composed of seven samples each, all having different surface textures. Set A samples were prepared from gypsum plaster and Set B samples from cement plaster mix. Set C consists of five different samples of con...
Fracture analysis of spun-cast concrete poles using the phase-field method Azim Azary, Ali; Göktepe, Serdar; Department of Civil Engineering (2017) Shrinkage is an important type of deformation in hardening concrete, which happens mainly in the cement paste and may cause significant damage if restrained. Spun-cast concrete poles are among structural members that are prone to this type of damage if not fabricated properly. They are used extensively in structures such as columns, piles, and utility poles to name a few. In this thesis, we study the differential shrinkage-induced cracking in spun-cast members computationally using the Phase Field Method wi...
Development of a safetyinspection methodology for river bridges Berk, Aysu; Yanmaz, Ali Melih; Department of Civil Engineering (2006) River bridges get damaged or even collapse because of various reasons, such as development of adverse hydraulic conditions during severe floods, disastrous earthquakes, deficiencies in structural and geotechnical design, material deficiencies, or other unexpected external factors. Failure of service at vital lifelines, bridges, can lead to loss of several lives and properties, traffic disruption, and/or deficiencies in daily usage. Existing structures should be monitored periodically for decision-making and...
