    A Cost Examination of Different Structural Systems For Low-Rise Building Construction
    (Osman SAĞDIÇ, 2022) Khalaf, Murad; Karaşin, Abdulhalim; Karasin, İbrahim Baran
    Economy reduces the cost of the resources used to achieve the planned results or outputs of the designed building, considering the appropriate level of quality. In other words, it is to provide the most appropriate input at the lowest cost. The construction cost consists of various stages during the building process. In this study, a comparative study was made in terms of the structural design and initial construction cost of a building assumed to be located in an earthquake zone according to the regulations. A Building which belongs to a reference building of two floors, detached (not surrounded by any building in any side), total area of 566 square meters, without basement. According to this project, which considered as a reference, two different structural alternatives to the building were created. The first alternative is of the masonry building type (besieged masonry building). The supporting walls of these structures are made of cut basalt stone and are surrounded by horizontal and vertical reinforced concrete beams. In this building solid concrete slab system with a thickness of 12 cm was considered. In the second, reinforced concrete considered with the same architectural features as the first structure. Based on TBYD 2018, these two alternatives are taken as the ZB floor class. For each alternative, the quantity cost-based calculation and the material-based calculation were calculated separately. As a result he cost values of the mentioned alternatives have been determined as 752.9 TL/m2 and 553.51 TL/m2, respectively, for the rough construction unit cost for reinforced concrete and masonry models, respectively. The fact that the amount of reinforcement and concrete in the reinforced concrete structure model is relatively higher than in the masonry model has been an important factor in the unit cost.

    Farklı Dolgu Tipleri için Çerçevelerin İtme Analizi ile Kıyaslanması
    (Osman SAĞDIÇ, 2022) Karasin, İbrahim Baran; Öncü, Mehmet Emin
    Depreme dayanıklı yapı tasarımı, gerçekleşen yıkıcı depremler neticesinde önemini giderek attırmaktadır. Jeolojik hareketler sonucu gerçekleşen bir doğa olayı olan deprem, deprem etkisi altındaki yapıların davranışlarına göre doğal afete dönüşebilmektedir. Bu çalışmada, yapılar üzerindeki deprem etkisini azaltmak amacıyla güçlendirilmiş bir duvar modeli diğer çerçeve tipleri ile kıyaslanmıştır. Bu güçlendirilmiş duvar modeli ile yapının, perdeli sistemlere göre daha sünek, boş çerçeveli sistemlere göre ise daha rijit olması amaçlanmıştır. Performansa dayalı tasarım kapsamında güncel ve yaygın olarak kullanılmakta olan Statik İtme Analizi (Static Pushover Analysis) kullanılmıştır. Pushover analiz metodu detaylıca izah edilmiş olup tüm modellere uygulanmıştır. Analizler ile kıyaslama yapılabilmesi amacıyla tek katlı çerçeve modelleri; boş çerçeve, perdeli çerçeve ve güçlendirilmiş duvar modeli ile modellenen çerçeve kendi içinde 15x15 ve 20x20 (santimetre) olmak üzere iki farklı tipi olup, toplam 4 modeldir. Bu modelller süneklik ve rijitlik açılarından karşılaştırılmış ve yorumlanmıştır.

    The effect of different negative parameters on the performance of steel structures
    (Bitlis Eren Üniversitesi, 2020) Işık, Ercan; Kaya, Berfin; Karasin, İbrahim Baran
    In this study, we present the effect of various negativity parameters on steel structures that cause post-earthquake damage based on performance-based assessment. In accordance with this purpose, eigenvalue and pushover analysis are carried out for different negativity parameters such as number of story, soft story, short column, hill-slope effect and irregularity in plan for a sample steel structure in this study. Structural models were created over the reference building to cover each negativity parameter within the scope of this study. Natural vibration period, base shear force, target displacements for damage estimation and stiffness values are obtained for each structural model separately. The comparisons with the reference building model results are made. The effect to behaviour of structures is determined and a reduction coefficient is proposed, for each negativity parameter, respectively. The proposed coefficients can be used to determine the risk priority in steel structures. It was concluded that each negativity parameter considered in this study reduces the behaviour of the building under the effect of earthquakes.
