All the tested specimens were nominally 6.2-m long W16×26 beams made of ASTM A992 steel. Each specimen was supported by one of the two following connections: (i) simple support (Tests 1 through 8), and (ii) double-angles bolted to laterally braced support columns (Test 9). The midspan of each specimen was exposed to an open-flame fire using the 1-m2 natural gas burners. The burner was located 1.1 m below the bottom flange of the beam at midspan. A four-point flexural loading scheme was used to apply concentrated forces at two locations 2.44 m apart around midspan. The data included temperatures, the heat release rates from the burner, and structural measurements including forces, displacements and strains. The Type B standard uncertainties in various measurements were also included. Overall, the test results showed that the heating rate of the specimen was sensitive to the prescribed heat release rate-time relationship. However, the thermal gradient developed in the fire-exposed cross sections of the beam never achieved linearity under the localized fire exposure. Regardless of the connection types and fire conditions (i.e., steady-state or transient-state fire), the beams exhibited a similar behavior and failure mode. When subjected to combined fire and flexural loads, the beam specimens exhibited the lateral-torsional buckling followed by runaway vertical displacements at midspan.
