| 摘 要： | 为研究火灾后配筋陶粒混凝土结构的受力性能,对一组陶粒混凝土简支梁进行高温过火及火灾后的常温加载试验.与火灾前相同陶粒混凝土和普通混凝土构件进行对比,过火后试件的正截面受弯和斜截面受剪承载力均有不同程度的降低.同时,对陶粒混凝土试件的高温过火及过火后的加载试验进行有限元模拟,并将数值模拟结果与试验结果进行对比分析.

| Abstract: | To study the mechanical properties of reinforced ceramsite concrete structure after fire,experiments on fire resistance performance of a group of simple supported beams and static loading tests after fire were carried out.Comparing with the beams before fire,the bending and shear properties of ceramsite concrete beams after fire all reduced in different degrees.At the same time,the finite element analysis on the ceramsite concrete beams after fire was carried out,and the results were compared with the those of experiment. |

| Keywords: | after fire ceramsite concrete simple supported beam bearing capacity of normal section bearing capacity of oblique section |
