FIRE RESISTANCE PERFORMANCE ANALYSIS OF HIGH

Jun 04, 2018 · The effects of the parameters on the fire resistance of high-strength steel Q550 column with a rectangular hollow section under axial compression were studied with an emphasis on the load ratio, initial imperfection amplitude, slenderness ratio and sectional dimensions. The results indicate that the load ratio is the main factor affecting the High Temperature Mechanical Properties of High Strength Jul 20, 2018 · Abstract. This paper reports the results of an experimental study on high temperature mechanical properties of high strength structural steel (HSSS) produced in accordance with Chinese materials standards. Steady-state tensile coupon tests were carried out on specimens made of China grade steels of Q550, Q690 and Q890.

The chemical composition of base steel (in wt.%) is C 0.18, Mn 2.00, Cr 0.80, Ni 0.80, Cu 0.80, Si 0.60 and Fe in balance. The microstructure of Q550 steel consists of low carbon bainite and lath martensite.

Influence of Cooling Rate on the Microstructures and

A Q550 high strength steel was selected at two different cooling rates through ultra-fast cooling process, and its microstructures and strengthening mechanisms were analyzed. The results show the bainite transformation temperature of the steel decreased with the increasing of cooling rate.The ultra-fast cooling process can improve the performance of Q550 compared with the conventional cooling Investigation on Postfire Residual Capacity of High Sep 09, 2020 · This paper experimentally and analytically investigates the fire and postfire behavior of axially restrained high-strength steel columns. Tests on the buckling behavior during heating as well as the residual load-bearing capacity after heating are first conducted on the column specimens made of Grade Q550 steel with a yield strength of 730 MPa.

Johnson-Cook Strength Model Constants for VascoMax 300

Jul 28, 2006 · High-strength structural steel is the tendency in modern construction practice. In this study, quasi-static tension tests and dynamic tests for Q550 with strain rate from 0.00025 to 3831 s{sup 1} were conducted. Material properties and statistical analysis of high Jan 01, 2021 · High-strength structural steels exhibit appreciable strength but reduced deformability compared to normal-strength steels. The yield-to-tensile ratios for Q550D, Q690D, and Q890D are more than 0.90, while the elongations range from 12% to 20%, indicating that these three structural steels are prohibited according to current Chinese seismic code.
