Merdiven basamaklarında, iç ve dış zemin döşemelerinde kullanılan doğal taşlar araç ve yaya yüklerine maruz kalmaktadır. Yapı taşları genellikle farklı ölçülerde ebatlandırılmış plakalar şeklinde üretildiğinden bu malzemelerin eğilme dayanımı son derece önemli bir parametredir. Plakaların boyutu ve kalınlığı, destek noktaları arasındaki mesafe, kayacın eğilme dayanımına göre tespit edilebilmektedir. Bu çalışmanın başlıca amacı, yapı taşı olarak kullanılan tüflerin eğilme dayanımı ile uygulaması kolay ve düşük maliyetli mühendislik özellikleri arasındaki ilişkileri araştırmaktır. Bu çalışmada, 27 adet tüfün eğilme dayanımı (FTS), darbe dayanımı (DN), kayaç darbe sertlik numarası (RIHN), kaya dayanım katsayısı (CRS), darbe dayanım indeksi (ISI), yassılık indeksi (FI), İsveç kırılganlık indeksi (S20) ve porozite (P) değerleri belirlenmiştir. Tüflerin FTS değerinin tahmini için basit ve çoklu doğrusal regresyon analizleri (SPSS) gerçekleştirilmiş ve denklemlerin doğrulanması için F ve t-testleri kullanılarak denklemler doğrulanmıştır.
Natural stones used in the stairs, in the ground floor and outdoors are exposed to vehicle and pedestrian loads. Since structural stones are usually produced in the form of different-dimensional plates, the inclination resistance of these materials is an extremely important parameter. The size and thickness of the plaques, the distance between the support points, can be determined by the slider's inclination resistance. The main objective of this study is to explore the relationship between the inclination resistance of the weapons used as a building stone and the easy to apply and low-cost engineering features. In this study, 27 pipe tendance resistance (FTS), hit resistance (DN), rock hit hardness number (RIHN), rock resistance ratio (CRS), hit resistance index (ISI), flatness index (FI), Swedish vulnerability index (S20) and porosite (P) values were determined. Simple and multiple linear regression analyses (SPSS) were performed for the estimation of the FTS value of the pups and the equations were verified using F and t tests for the verification of the equations.
Natural stones used in stair treads, interior and exterior floors are exposed vehicle and pedestrian loads. Since the building stones are generally produced in the form of plates of different sizes, the flexural tensile strength of these materials is an extremely important parameter. The size and thickness of plates, the distance between the support points can be determined according to the flexural tensile strength of the rock. The main aim of this study is to investigate the relationships between flexural tensile strength of tuffs used building stones and engineering properties which are easy to implement and low cost. In this study, flexural tensile strength (FTS), impact strength (DN), rock impact hardness number (RIHN), coefficient of rock strength (CRS), impact strength indeks (ISI), flakiness index (FI), Swedish brittleness index (S20), and porosity (P) of 27 tuffs were determined. Simple and multiple linear regression analyses (SPSS) were performed for estimating FTS of tuffs and F and t-test were used to verify the equations. The results show that there were good and satisfactory relationships between FTS and engineering properties of tuffs. Furthermore, the multiple models have a better predictive efficiency than simple models and they can be applied for predicting FTS of tuffs with reasonable confidence. When the derived equations are examined, tests such as S20, ISI, CRS, FI and P are very effective among the parameters used in predicting the FTS.
