Abstract

Concrete short-span beams might suffer bond splitting failure during a large earthquake due to their short development length. Steel Fiber-Reinforced Concrete is known to be effective in enhancing the performance of concrete members. However, there are not many studies on bond splitting failure of Steel Fiber-Reinforced Concrete members. Therefore, we carried out bond splitting tests of Steel Fiber-Reinforced Concrete assuming corner and side split type failures. We proposed an evaluation method for bond splitting strength considering their material properties. In addition, the evaluation method was verified using the results of tests of short-span Steel Fiber-Reinforced Concrete beams.

采用钢纤维加固混凝土的短墩梁的附着裂缝状

混凝土短跨梁由于其发展长度较短，在大地震作用下可能发生粘结断裂破坏。众所周知，钢纤维增强混凝土在提高混凝土构件的性能方面是有效的。然而，对钢纤维混凝土构件的粘结开裂破坏研究并不多。为此，对钢纤维混凝土进行了角裂和边裂破坏的粘结劈裂试验。提出了一种结合材料特性的键裂强度评价方法。并以短跨钢纤维混凝土梁的试验结果对评价方法进行了验证。

期刊介绍： The Architectural Institute of Japan’s Journal of Structural and Construction Engineering aim to pursue theories for building and maintaining pieces of architecture as well as the cities or areas surrounding them, and to accumulate and systematize the knowledge needed to put those theories into practice. The Journal of Structural and Construction Engineering focuses on research results in the specific fields of “building materials and construction” and “structures.” Accordingly, it compiles articles in the following areas, disseminates relevant information, and hosts discussions: ・Concrete, steel, and inorganic materials ・Timber and organic materials ・Finishing materials ・Construction and quality management ・Applied mechanics ・Loads and reliability on structures ・Building foundations ・Timber structures ・Steel structures ・Reinforced concrete structures ・Shell and spatial structures ・Engineering seismology and structural dynamics ・Other composite structures
