| 摘要: | 钢筋笼吊装过程中的状态可以看作是在分布荷载和集中荷载共同作用下的多支承悬挑梁, 其中支承点对应于吊点. 本文基于奇异函数和拉普拉斯变换, 求解了梁的挠度曲线方程, 并结合遗传算法, 提出了一种设置直列式钢筋笼最优吊点的新方法. 通过算例和数值模拟验证了该方法的可行性. 结果表明, 与现有的吊点确定方法相比, 该方法能更有效地控制钢筋笼在吊装过程中的变形. |
| Abstract: | The condition of the reinforcement cage during hoisting can be treated as a multi-supported overhanging beam under the combined action of distributed and concentrated loads, where the support corresponds to the hoisting point. Based on the singular function and Laplace transform, the deflection curve equation of the beam is solved, and a new method of setting the optimal lifting point of the in-line reinforcement cage is proposed in combination with the genetic algorithm. The feasibility of the method is evaluated and verified by calculation examples and numerical simulation. The results show that the proposed method can control the deformation of the reinforcement cage during hoisting more effectively than the existing method of determining the hoisting point. |
