摘要
本文借助大型通用有限元软件ANSYS分析研究了在不同跨高比情况下双连梁的受力性能。文中共设计了五组模型,跨高比分别为2.4、2.7、3.0、3.4、4.0。分析结果表明:随着连梁跨高比的逐渐增大,各模型连梁所承担的总内力均逐渐减小,结构顶点的位移逐渐增大,刚度逐渐减小。同时,在每个模型中,上梁所承担的剪力比下梁小,上梁所承担的轴力(绝对值)比下梁大,上梁与下梁所承担的弯矩基本相同。
In this paper,with the finite element software ANSYS,the stress performance of the dual binding beams in different span-depth ratio was studied. We've designed five sets of model,the span-depth ratio were 2. 4,2. 7,3,3. 4, 4. The results show that: with the span-depth ratio of coupling beam increases gradually,the total force that each model coupling beam assumed decreases gradually,and the vertex displacement of each structure increases gradually,stiffness decreases gradually. Meanwhile,in each model,the shear that the upper beam bears is less than the lower beam,and the axial force( absolute value) that the upper beam bears is more than the lower beam,the moments borne by the upper and lower beam are substantially the same.
