| 摘 要： | 本文通过对混凝土梁板构件按ISO 834标准升温曲线进行的火灾试验,探索了火灾下混凝土发生爆裂的影响因素及规律;通过试验发现,混凝土强度等级越高、混凝土含水率越高、迎火面混凝土压应力水平越高,火灾中混凝土越容易爆裂或爆裂越严重,并得到了混凝土强度等级、混凝土含水率及混凝土应力水平与爆裂的相关曲线.

| Abstract: | With reference to ISO834 standard heating curve,experiments on concrete slabs and beams subjected to fire are carried out.Regular patterns of concrete spallation and factors affecting the spallation are studied.Experiments show that the higher the strength or moisture content of concrete,or the higher the compressive stress level of the concrete surface that faces fire,the easier and more serious the spallation will be.Curves of relationships between spallation and the factors mentioned above are established. |
