    Damage Assessment of Urban Interface Masonry Buildings after a Severe Wildfire along with a Comparison of NRC-2018
    (Bursa Teknik Üniversitesi, 2025) Soyer, Aslan; Ghatte, Hamid Farrokh
    The wildland-urban interface (WUI) has emerged as a focal point of wildfire management and community resilience efforts worldwide. The WUI, defined as areas where settlement reaches natural landscapes, presents a unique set of challenges for wildfire mitigation. On the other hand, the performance of the buildings throughout the fire and the provision of proper fire safety measures for structural members is one of the essential aspects of the design of buildings and infrastructures. This study attempts to emphasize the seriousness of the wildfire effects on the WUI in the Mediterranean neighborhood, especially in Turkey. For this purpose, the efficiency of the extreme heat throughout the wildfire on masonry buildings in Manavgat, Turkey (July-August 2021) was investigated in terms of performance and structural damages. Failure mechanisms and the damages that occurred during the wildfire are reported for masonry buildings as the main structural system in this neighborhood. Commonly used technical documents of a national guide for WUI fires presented by the National Research Council Of Canada (NRC- 2018) were employed to compare the condition of the buildings. Turkish standards do not cover wildfire conditions in terms of the WUI buildings. The in?uences of the materials, the type of cladding, and various types of roofs were investigated in masonry buildings. For this purpose, 121 masonry buildings in Manavgat, Turkey were examined in terms of performance and damage. Furthermore, a comparison of the data with WUI-NRC (2018) is represented to investigate some serviceable recommendations based on the investigation to reduce damages in buildings subjected to wildfire. Finally, an introduction to have detailed written local WUI regulations for masonry buildings to have enough safety in terms of life and economy.

    Durability Performance of Concrete Incorporating Two Diverse Aggregates Acquired From Şanlıurfa Quarries
    (Bursa Teknik Üniversitesi, 2025) Danışman, Emre; Ghatte, Hamid Farrokh
    In recent decades, Türkiye has dramatically increased the use of concrete as a main construction material and has become the leader among European concrete-producing countries. Therefore, the preparation of proper material for concrete is one of the great changes in terms of using sustainable components in concrete. Türkiye has considerable aggregate resources owing to its extensive mountains, which sets a foundation for investigating the aggregates. The granulometry of rock samples is one of the main sources of the aggregates. By employing the experimental methodology, the current study examines and compares the physical, mechanical and chemical properties of aggregates and the granulometry of rock samples from Seferoğlu quarry and Yetimoğlu quarry in Şanlıurfa province. For this purpose, physical properties were determined by specific gravity, volumetric weight, organic matter determination, alkali-silica rectification, freeze-thaw resistance, Los Angeles abrasion, high-temperature experiment, capillary water permeability, ultrasonic velocity measurement and pressure test. Calculating the concrete mix according to the ASTM standard prepared cubic concrete compressive strength of 15x15x15 cm. The results of compressive strength of 7 and 28 days of concrete were obtained. The results revealed that the aggregates demonstrated better physical and mechanical properties concerning the depletion of natural aggregates.
