Residual Strength of Steel Structures After Fire Events

Jan 04,2019 PDF RESIDUAL STRENGTH OF STRUCTURAL STEELS#0183;It is an essential task for engineers to evaluate the residual strength of a fire-damaged steel structure,especially when collapse does not occur during the fire event.First of all,the mechanical properties of structural steels after fire were investigated through the experimental data.The stressstrain relationship model considering fire events was established.Residual Compressive Strength of Short Tubular Steel Hebor et al.[1] and Nazari et al.[2] used a numerical approach to evaluate the residual compressive strength of locally corroded steel tubular members in o shore structures by considering the depth and circumference of the corrosion.They also suggested equations to predict the residual strength of tubes with patch corrosion.RESIDUAL STRENGTH OF STRUCTURAL STEELS SN400,Download PDF Sorry,we are unable to provide the full text but you may find it at the following location(s) https://doi/10.14311/asfe.(external link) https
