摘要
利用ANSYS有限元软件模拟分析防火涂料对钢-混凝土组合梁的抗火性能的影响。结果表明,没有防火涂料时,组合梁尤其是腹板的温度迅速上升;随着防火涂层厚度的增加,组合梁的温度降低,升温速率减缓;随着防火涂层厚度的增加,温度降低幅度减小。
Under the protection of fireproof coating, fire resistance of steel-concrete composite beams was researched hy the finite element software ANSYS. The results showed that the temperature of com- posite beams, especially the web rises quickly without fireproof coating. With the thickness of fire retardant coating increase, the temperature of composite beams are lower, and the temperature in creasing rate is smaller. The thicker the coating, the smaller the temperature reducing amplitude.
