Mechanical properties and modelling of superior high-performance steel at elevated temperatures

Mechanical Properties of S235 Steel Protected with Intumescent Coatings Under High Temperatures: An Experimental Study

“…Despite the advances in fire-resistant materials, significant vulnerabilities still exist, particularly with cold-formed thin-walled steel profiles. These profiles, which are commonly used due to their cost-effectiveness and ease of installation, are less resistant to fire compared to their hot-rolled counterparts, a fact that has been well documented in various studies [1][2][3][4][5][6][7][8][9]. For instance, research has shown that a marked decrease in mechanical strength and stiffness occurs as temperatures rise, with critical degradation occurring between 550 and 600 • C [10][11][12][13][14][15].…”

“…After the fire incident at the American World Trade Center on September 11th, academics and structural engineers turned their attention to examining the behavior of steel during and after fires. They have carried out numerous studies to explore the behavior of steel exposed to fire [1][2][3][4][5][6][7][8][9]. Cold-formed steel profiles are less fire-resistant than hot-rolled profiles.…”

Experimental and numerical investigation of S700 high strength steel CHS beam–columns after exposure to fire

“…Research on high strength steel structures in fire and post-fire scenarios has been conducted, with the key experimental and numerical studies introduced herein. Qiang et al [1,2], Xiong and Liew [3], Li and Young [4] and Ban et al [5] conducted a series of steady and transient state tests on different grades of high strength steel and investigated their mechanical properties and stress-strain curves at elevated temperatures. On the basis of the steady and transient state test results, stiffness and strength reduction factors were determined and new predictive models were developed.…”

Mechanical properties of heat resistant steel serviced for 30 months

“…The results show that the influence of temperature on mechanical properties of different types of high strength steel is different. Ban et al [4] studied the mechanical properties of SHP steel at high temperature and proposed a constitutive model. The results show that the mechanical properties of SHP steel are significantly different from those of conventional low carbon steel and refractory steel.…”
