Low temperature fatigue tests of reinforced straight thread sleeve connections of a high speed railway station in Northern China

The low temperature constant amplitude fatigue tests of reinforced straight thread sleeve connections in rail floor structure of a high speed railway station in Northern China were carried out to verify their fatigue resistance under dynamic loadings, in order to control the construction period, and...

description: The low temperature constant amplitude fatigue tests of reinforced straight thread sleeve connections in rail floor structure of a high speed railway station in Northern China were carried out to verify their fatigue resistance under dynamic loadings, in order to control the construction period, and to ensure the quality, safety and reliability of the structure. A total of 13 connection specimens fabricated from HRB400 steel reinforced bars with diameters of 28 mm and 32 mm were prepared. The fatigue tests were controlled by constant stress range of 100 MPa and a low temperature controlling equipment was specially designed to achieve conditions with low temperatures of -10 degree C and -20 degree C. Among the thirteen tested specimens, four failed due to fatigue before 2.0 million cycles and the remaining met the fatigue resistance requirement of enduring 2 million cycles. The test results indicate that the reinforced straight thread sleeve connections satisfy the fatigue performance at low temperatures required by the engineering project according to "Technical Specification for Mechanical Splicing of Steel Reinforcing Bars(JGJ 107-2010)". The present study provides an experimental basis for applications of reinforced straight thread sleeve connections in rail floor structures subjected to dynamic train loadings.
