Local Buckling of RHS Members at Elevated Temperatures

摘要

The aim of this study is to find a simple calculation method for calculating thefire resistance of certain structures that may fail by local buckling. A series of fire tests was carried out for cold-formed rectangular hollow sections (RHS 200 x 200 x 5 and RHS 150 x 100 x 3) of structural steel S355. Both concentric and eccentric compression tests were performed. The fire tests were transient-state tests (heating rate 10 deg C per minute under constant load) on unprotected specimens.
