Intrauterine fetal fracture is rare and hardly ever is a diagnosis made before the baby is born. A 32-years-old, woman at 37+6 weeks gestation was admitted in labor. The patient had no history of abdominal trauma and disease. The length of fetal femur was

When steel fiber reinforced concrete is used as an underground cavity or a lining of tunnel, the SFRC is subjected to loads which differ in type from those present in standard testing methods. This study is worthy of notice on this point. This study is aimed to investigate an experimental study on flexural-compression behavior of steel fiber reinforced concrete. When a combined bending moment-normal force loading is characteristic in such shells, it were aimed to construct a data for design under such conditions An experimental variables are steel fiber content, shape ratio, angle of end mill. Total 126 specimens using four different kinds of steel fiber products were evaluated from loading test. From the test results, it was known that a fracture occurred before reaching ε_(cu). A tensile strain was gauged 5‰ at that time. SFRC specimens occurred a tensile fracture, It was known that a location of neutral axis was not changed untill a crack occurred on specimens.
