［摘要］對4個H型鋼梁試件進行了火災(zāi)試驗研究。H型鋼梁端部采用柔性連接的梁柱節(jié)點形式，探討了H型鋼梁在火災(zāi)作用下的變形、溫度內(nèi)力和梁的外表面溫度分布，并給出了荷載和跨度對采用柔性連接節(jié)點形式的H型鋼梁抗火性能的影響。為柔性連接鋼梁火災(zāi)行為的理論研究提供了依據(jù)。

Abstract:In order to investigate the structural characteristics of H-haped steel beams under fire, an experimental research which consisted 4 specimens had been carried out. Beamcolumn joints of the H-shaped steel beams are flexible connections. The deformation, axial force owing to thermal effects and temperature distribution of steel beams′ surface are presented, and the effects of different load and span on the behaviors of Hshaped steel beams with flexible connections are also given. Results provide a basis for the theoretical research of steel beams with flexible connections.
Keywords:fire; steel beams with web-cleat connections; axial force owing to thermal effects; temperature distribution
