In these two research articles, structural engineer Michael Drury examines the structural behavior of one-way composite steel floor beams under different fire exposures.
Testing highlights include:
-
Duplicate pair of composite floor beams were tested under standard and natural fire
-
Both had the same SFRM protection, load, and partial restraint of thermal expansion
-
Composite slab and bolted shear tab connections retained integrity thru both tests
-
Flexural response of both specimens is governed by steel beam temperature increase
-
Thermo-structural results are used for numerical validation in Part 2 of this study
Analysis highlights include:
-
Duplicate pair of composite floor beams are analyzed for standard and natural fire
-
Both had the same SFRM protection, load, and partial restraint of thermal expansion
-
Thermal FE results conservatively predict experimental beam and slab temperatures
-
Structural FE predictions of fire-induced deflection compare well with test data
-
Parametric variations in loading and connection rotational stiffness are evaluated
Both articles were originally published in the Journal of Constructional Steel Research (Volume 202, March 2023).
