摘要
通过对槽形梁、I形梁、矩形梁、T形梁、圆形梁、圆环梁和花篮梁七种梁截面进行对比分析,研究固定截面尺寸比例下不同截面的受力情况和对造价的影响。对圆环梁、T形梁和花篮梁,计算了它们在不同的截面尺寸比例下的抗弯截面系数,得出了截面承载性能随截面尺寸比例的变化规律,从而对梁截面的造价做了进一步的优化。
This paper analyzed the influence of beam cross-section on the distribution of the forces and the project cost by comparing seven kinds of beam cross-sections under the same section size ratio .The seven kinds of beam cross-sections are channel beams, I-shaped beams, rectangular beams, T-shaped beams, circular beams, ring beams and basket beams. Especially for ring beams, T-shaped beams and basket beams, their section modulus in bending was calculated and the regularity for change of sections' carrying capacity with the varying section size ratio was got, for further reducing the cost of beams.
