Jan 15, 2021 · Wang et al. [16, 20, 26] conducted a series of comprehensive tests to study creep deformation for different types of high-strength Q460 and Q690 steels and low-alloy Q345 steel at different high temperatures; they also proposed a creep model for Q460 and Q690. However, despite increasing efforts to understand creep behaviour at high Assessment of thermal properties of various types of high Accurate assessment of the thermal properties of steel is a key issue in the fire simulation and design of steel structures. Thermal property tests were conducted for seven types of high-strength steels (HSSs), namely Q460, Q500, Q550, Q620, Q690, Q890, and Q960 steels, along with conventional mild steel
