This study evaluates the possibility to use timber members as a complete or partial fire protection for steel beams. The hybrid elements considered are composed by I or T-shaped steel profiles partially or fully encased into timber members. The thermal behavior is analyzed by using numerical ...
If steel is exposed to temperatures of 500°C and above, the structural integrity and stability is at risk, which could result in the building collapsing. An effective fire safety strategy can reduce this risk, including the installation of fire protection to steel beams and columns. ...

A fire and heat protection wrapping system is described for wrapping structural steel such as steel columns, beams and open web joists used in steel construction of all types of edifices. The protection wrapping system includes a concentric composite laminate structure having a plurality of concentric...
to block the flame and directly burn the steel structure to reduce the speed of heat transfer. Delay the temperature rise of the steel structure and the time when the strength is weakened. But no matter what method is adopted, the principle is the same. The fire protection measures for ...
