Title: Direct Tensile Fatigue of Concrete by the Use of Friction Grips
Author(s): Mitsuru Saito and Satoru lmai
Publication: Journal Proceedings
Appears on pages(s): 431-438
Keywords: fatigue (materials); fatigue tests; finite element method; plain concrete;stress-strain relationships; tensile strength; tensile stress; tension tests.
Abstract:Tensile fatigue tests were conducted by providing fhe necked prismatic specimens with tensile loads using the friction grip. The test results show that plain concrete exhibits no fatigue limit in tensile fatigue at less than 2 miilion cycles and that the fatigue strength for 2 million cycles is 72.8 percent of the sfatic tensile strength. Tensile fatigue strength is considerably higher than compressive and flexural fatigue strengths obtained bv several workers. The test results also indrcure that stress-strain relations under tensite repeated loading are approximately linear, their slopes constant wifh the number of cycles.
