| 摘 要： | 由于铝合金材料的密度和比热容与钢材相比差别较大,在ISO 834标准升温条件下,铝合金构件的升温过程与钢构件存在明显差异.为了得到有轻质保护层铝合金构件的升温计算简化公式,采用增量法计算了ISO 834标准升温下的轻质保护层铝合金构件升温曲线,并对数据进行非线性拟合分析,得到了有轻质保护层铝合金构件升温计算简化公式,进...

| Abstract: | Since
the density and specific heat of aluminum alloy are different from that of
steel, the heating process of aluminum alloy component is obviously different
from that of steel component under ISO 834 standard heating condition. In order
to get a simplified method for calculating the temperature rise of aluminum alloy
components with light fire protection, the temperature rise curve of aluminum
alloy components with light fire protection under ISO 834 standard temperature
curve was calculated by incremental method, and the data were analyzed and
fitted by nonlinear fitting. A simplified method for calculating the temperature
rise of aluminum alloy components with light fire protection was obtained, and
then the thickness of fire protection could be determined according to the
critical temperature and the limit refractory time of aluminum alloy
components. The results show that the temperature rate of aluminum alloy members
with the same section is faster than that of steel members under the same
heating conditions |
