Ağır taşıtlarda çarpma enerjisi sönümleyici arka koruyucu tampon tasarımı
Sert, Mustafa (İskenderun Teknik Üniversitesi / Mühendislik ve Fen Bilimleri Enstitüsü / Makine Mühendisliği Anabilim Dalı, 2018)Ülkemiz karayollarına her yıl binlerce trafik kazası meydana gelmektedir. Bu kazaların dağılımına bakıldığında, hafif araçların ağır vasıtayla çarpışması ve altına girmesi sonucunda aracın ezilmesi ve yolcuların ciddi ... -
Determination of optimum post embedment depth for C120 steel posts using field and full scale crash test
Atahan, Ali Osman; Büyük, Murat; Örnek, Murat; Erdem, Musab; Türedi, Yakup (Taylor & Francis Ltd, 2019)C120 steel sections are the most widely used post shapes in European guardrail designs. The design length of these posts is determined based on guardrail containment level and engineering judgment. The soil properties where ... -
Evaluation of 12 m long turned down guardrail end terminal using full-scale crash testing and simulation
Atahan, Ali Osman; Erdem, Muhammet Musab (Brazilian Association of Computational Mechanics, 2016)The beginnings and ends of guardrail designs have the function of providing adequate anchorage for the rest of the system. They should also demonstrate crashworthy performance and should not pose any hazard for errant ... -
Soil Based Design of Highway Guardrail Post Depths Using Pendulum Impact Tests
Örnek, Murat; Atahan, Ali Osman; Türedi, Yakup; Erdem, Muhammet Musab; Büyük, Murat (Univ Maribor, 2019)Guardrails are passive road restraint systems (RRS) used at roadsides and medians to improve road safety. In the case of inadequate post embedment depth of soil driven posts may not function as intended and design cannot ... -
Traffic Safety at Median Ditches: Steel vs. Concrete Barrier Performance Comparison Using Computer Simulation
Yücel, Ayhan Öner; Atahan, Ali Osman; Arslan, Turan; Sevim, Umur Korkut (Mdpi, 2018)In Turkey, concrete V-shaped ditches are formed at the median section of divided highways to provide drainage. Recent accidents show that these ditches actually present safety risks to vehicles entering the medians. Vehicles ...
