Fatigue Behavior of Cracked High-Strength Steel Plates

Dec 06, 2016 · However, limited fatigue experiments have been conducted for cracked high strength steel plates with carbon fiber-reinforced polymer (CFRP) sheets. This paper describes an investigation into the fatigue behavior of unstrengthened and CFRP strengthened cracked Q345, Q460, and Q690 steel plates. Mechanical Properties of High-Strength Q690 Steel at May 05, 2018 · Standard tensile tests were conducted to obtain the mechanical properties of Q690 steel at temperatures ranging from 20 to 900°C. Test data on strength and elastic modulus properties show that the reduction factors developed for carbon (mild) steel are not applicable to high-strength Q690 steels. Post-fire mechanical properties of high strength Q690 May 01, 2017 · This paper investigates the post-fire mechanical properties of high strength structural steel (HSSS) of Q690, the Chinese Grade of steel with nominal yield strength of 690 MPa. The test specimens were first heated to a temperature level (ranging from 300 °C to 900 °C), and then cooled down to ambient temperature.
