三面受火小偏压SRC柱耐火极限试验
Experimental fire resistance of steel reinforced concrete subjected to 3-side heating with a small eccentricity load
摘要
Abstract
Locating in different positions, columns in structures may be heated from l-,2-,3- or 4-side, which will lead to a different fire behavior because of different heating situation. To discover the behavior of steel reinforced con-crete (SRC) columns subjected to 3-side heating, two tests on fire resistance of eccentrically loaded SRC (steel rein-forced concrete) columns under ISO-834 standard fire are conducted. Temperature distribution, axial and lateral de-formations as a function of time, damage mode, fire resistance and related mechanisms are observed. From the results we can see, spalling or of concrete has visible influence on the temperature distribution and fire resistance. Load ratio and eccentricity are key factors to deformation and fire resistance of 3-side heated SRC columns. Test results can be taken as a reference to fire resistance design of SRC columns subjected to 3-side heating.关键词
