| 摘 要： | 采用ANSYS有限元程序计算三角形钢管桁架梁的挠度和应力,通过分别调整底边宽度A,结构高度B,杆件选型,以及采用高强钢的杆件,得到最小用钢量。结果表明:A=1800 mm或2100 mm,B=1500 mm时,调整弦管截面和钢材牌号,可以获得较小的用钢量。

| Abstract: | Used ANSYS finite element calculate deflection and stress of triangular steel truss beam, by adjusting the width of the bottom A, structural height B, the shape of structure, and high strength steel, we can obtain the smallest quantity of steel. The results indicate that when A = 1800 mm or 2100 mm,B = 1500 ram, adjusting the tube cross-section and steel grade you can obtain a smaller quantity. |
