在独柱桥墩的抗震设计中,为了实现投资与效益之间的平衡,并在追求最优解的同时显著提高其计算效率,结合模糊逻辑控制法、神经网络法、自适应遗传算法的优点,提出了一种可以考虑非线性的基于性能的独柱桥墩的抗震设计方法。对设计结果进行Pushover分析,其能力曲线与试验滞回环曲线骨架基本一致;将该设计流程应用于一座城市高架桥桥墩的抗震设计中。结果表明:与一般的基于性能的模糊遗传抗震设计方法相比,该方法可以方便、准确、高效地确定桥墩的最优设计模型,可以推广应用于桥梁工程的抗震设计中。
In the seismic design of single-column piers, in order to achieve the balance between investment and benefit, and in the pursuit of the optimal solution, the computational efficiency is significantly improved. Combined with the advantages of fuzzy logic control method, neural network method and adaptive genetic algorithm, A seismic design method based on the performance-based single column pier considering nonlinearity is proposed. Pushover analysis of the design results is basically consistent with the curve of hysteresis loop curve. The design flow is applied to the seismic design of a city viaduct pier. The results show that compared with the general performance-based fuzzy genetic aseismic design method, this method can determine the optimal design model of piers conveniently, accurately and efficiently and can be widely applied to the seismic design of bridge engineering.
