对非对称锥形张拉梁的承载力进行试验研究,并将试验结果与有限元分析结果进行对比。分别考虑在均布荷载、非对称荷载和跨中局部荷载作用下,研究大气压力对结构刚度的影响。结果表明:试验结果与有限元分析结果在各方面都比较吻合。提出一个基于双耦合常微分方程的有限元模型,用于分析均布荷载下梁的承载力。将张拉梁形状对其刚度的影响与非对称锥形张拉梁的荷载-挠度曲线进行对比。
The bearing capacity of asymmetric tapered tension beam is tested and compared with the results of finite element analysis. Considering the effect of atmospheric pressure on the structural stiffness under uniform load, asymmetric load and mid-span local load, respectively. The results show that the experimental results are consistent with the results of finite element analysis in all aspects. A finite element model based on double coupled ordinary differential equations is proposed to analyze the bearing capacity of beams under uniform load. The effect of the shape of the tension beam on its stiffness is compared with the load-deflection curve of the asymmetric taper tension beam.
