| 受弯下非对称锥形张拉梁的结构性能 |

| 摘 要： | 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。

Structural Behavior of Asymmetric SpindleShaped Tensegrity Girders Under Bending Loads |
| |
| Abstract: | The load bearing behavior of an asymmetric spindle shaped Tensegrity girder is studied experimentally and compared to finite element analyses.The influence of the air pressure on the stiffness of the structure is investigated for homogeneous distributed load,asymmetric distributed load and a local load at the center of the structure.An overall good correlation between experiments and finite element predictions was found.An analytical model based on two coupled ordinary differential equations is presented an... |
