Exposure Conditions

In this study, the fire resistance of steel composite beams typically used in building structures was investigated through standard fire and loading tests. For the tests, fire-exposure conditions depending on the steel section shape and load ratio applied to the beams were considered as the test parameters. Based on the test results, the applicability of fire design methods for composite beams recommended in current domestic and overseas fire design codes was analyzed. The results indicate that the current temperature-based design method and reduced flexural capacity method specified by the American Institute of Steel Construction may lead to the conservative fire design of steel composite beams owing to the underestimation of the effects of the fire-exposure conditions and load ratios.

Rigid Joints

This paper presents the design and development of moment connections between wide flange beams and square tubular columns in rigid frames. The connection is effected by means of coped strap angles used to transfer stress from the beam flanges to the sides of the column. The testing program comprised 23 specimens, including two standard rigid joints introduced to give a comparison basis for the [Formula: see text] curves.The results indicate that after adequate precautions have been taken to prevent the occurrence of brittle fracture in the strap angles a connection is obtained which can develop MP and sustain appreciable inelastic deformation, making it suitable for plastically designed frames. The rigidity of the connection is less than that of a standard connection but high enough for the joint to be termed 'nearly rigid'. Preliminary theoretical studies indicate that the effect of the relative loss of rigidity on the sway behaviour of multistory frames may be significant and that P-Δ effects should be investigated.All joints considered here comprised beams of flange width equal to that of a column face.A design method is proposed in the Appendix.
