| 摘要 | The presence of an axial load changes the system stiffness of an infante beam on a tensionless Winkler foundation, which also determines the solution form of the beam deflection. Five different closed form solutions depending on the axial load are analytically derived in this study. The beam deflections are systematically studied when it is subjected to various axial and transverse concentrated loads. Because the contact zone of a tensionless contact is not known a priori, it can cause a significant mathematical difficulty in solving various tensionless contact problems. In recent tensionless contact researches, the major efforts have been developing the efficient but complex algorithms to determine the contact zones. Five transcendental equations governing the contact zones, which are straightforward for numerical computations, are also analytically derived. The five closed form solutions can serve as a guide line for the further study of the beam tensionless contacts with more complex loading scenarios. Furthermore, the model of a beam on the Winkler foundation subjected to an axial load is also demonstrated to be applicable to various and different problems. |
