The influence of the physical properties of steel beams on section bending

The steel beam can be bent by rolling the steel beam in a three-roll plate bending machine, tamping the steel beam with a hydraulic cylinder or using a torch to heat.

Arching the steel beam by any method will increase its yield strength and tensile strength, but will reduce its ductility and toughness. However, research data indicates that the impact will be relatively small. For low strains of 1-3%, the tensile strength is only increased by 4%.

The arc will definitely fall within the low strain range of 1-3%.

The bending of the steel, "hot" or "cold", will cause some changes in the properties of the steel.However, the impact of changes is rare.

Modern steels designed by metallurgists with higher strength and toughness have made hot or cold bending safer than the past.
