工字型钢梁-砖拱组合楼板的有限元分析——长春市沙俄领事馆的楼板分析

Finite Element Analysis of Work Matrix Steel Beam-brick Arch Combination Floor Plank Floor Plank Analysis About Russia at Chinese Consulate

钢梁和砖拱组合楼板是一种独特的钢-组合结构,其组合形式的研究在国内外很少见.通过对其现场检测试验发现:这种结构虽然经过上百年的历史,承载力依然能够满足要求,利用有限元分析软件对钢梁-砖拱组合楼板的受力进行分析,并对钢梁-混凝土拱结构进行比较研究,最终通过ANSYS软件加载试验发现,钢梁-砖拱组合楼板与钢梁-混凝土拱组合都具有相同的破坏模式及变形趋势,且受力性能也优于砖拱.因此,钢梁-混凝土拱组合可以替代砖拱-钢梁的组合.

The steel beam combines with the brick arch floor plank is research that a kind of special steel-combination construction,its combination form at domestic and international seldom see.Pass as to it＇s of the spot examination experiments the detection：This kind of construction although through last a hundred years of history,load the dint to can satisfy the request still.making use of finite element analysis software to combine to the steel beam-brick arch the floor knothole is analyzed by dint proceeding,and proceed to the steel beam-concrete arch construction the comparison studies,end pass the software of ANSYS adds to carry to experiment the detection,steel beam-brick arch combination the breakage mode that floor plank combine with steel beam-concrete arch to all have the homology and transform the trend,and because the concrete compares the red brick more environmental protection,the flexibility mold measures too far larger than brick of the flexibility mold measures,suffering the dint function too better than brick arch.The for this reason concrete arch combine with steel beam and can act for brick arch and the combination of the steel beam.
