英语翻译
The yield strength of steel was 308MPa for Grade 43 steel (S275) and 390MPa for Grade
50 steel (S355);
.
The yield strength of the steel used in the anti-crack mesh was assumed to be 460 MPa;
.
The elastic modulus of steel was 2.1x105 MPa;
.
The average compressive strength of concrete test samples was 35 MPa,and this is used.
A uniform floor load of 5.48kN/m2 was applied to the whole building,using sand-bags for the
imposed portion,and this is assumed in the modelling.The temperature distributions across
the section of the steel beam and the depth of the slab are assumed to be invariant with
position within the fire compartment.These temperature distributions at any time in the test
are the averages of the recorded test temperature distributions at this time across the beam and
slab.The maximum recorded temperatures of the bottom flange,web and top flange were
834°C,816°C,and 764°C respectively,and the maximum recorded temperatures of the
bottom and top layers of the slabs were 481°C and 129°C respectively.In order to investigate
the structural behaviour of the restrained beam up to extremely high temperatures,these
temperatures have been extrapolated linearly,so that the maximum temperatures of the
bottom flange of the beam and the bottom layer of the slab become 1005°C and 637°C
respectively.The temperature of the bottom flange of the tested beam is used as the "key
temperature" which is quoted in all figures.
