摘要:
为探究不同橡胶替代率和钢纤维掺量对混凝土长期受力性能的影响,通过弯曲蠕变实验对混凝土小梁施加30%抗折强度的荷载并持续3天,结果表明,钢纤维的加入可以显著改善橡胶混凝土的蠕变劲度。同时基于蠕变实验数据,建立BP神经网络模型对钢纤维橡胶混凝土的蠕变劲度进行预测,并通过遗传蚁群算法(GAACOBP)对其进行优化,平均绝对百分比误差(MAPE)从16.28%降低至3.3%,有效提高了模型的准确性和稳定性。
Abstract:
 In order to investigate the effects of different rubber replacement rates and steel fiber admixture on the long term stress performance of concrete, a load of 30% flexural strength was applied to concrete beams by bending creep experiments for 3 days, and the results showed that the addition of steel fiber could significantly improve the creep stiffness of rubber concrete. Meanwhile, based on the creep experimental data, a BP neural network model was established to predict the creep stiffness of steel fiber rubber concrete, and it was optimized by genetic ant colony algorithm (GAACOBP), and the Mean absolute percentage error was reduced from 16.28% to 3.3%, which effectively improved the accuracy and stability of the model.
