钢筋混凝土剪力墙结构抗震性能优越且造价合理,广泛用于抗震烈度较高的地区。准确地预测剪力墙的滞回性能与骨架曲线,直接决定了结构设计与分析的准确度与可靠性。该文提出了一种基于深度学习的剪力墙结构滞回性能预测方法,可以根据结构的基本设计参数(如材料属性、几何尺寸、荷载工况等),直接预测出其承载力。通过3组剪力墙的滞回试验预测1组结构的滞回曲线,结果表明:通过比较时域的特征,深度学习方法具有较高的预测精度。通过与有限元仿真结果对比,深度学习仅需输入不同参数就能够快速预测滞回曲线,其优势还在于具有较高的计算效率,而有限元仿真需要几何建模、本构模型选取、材料属性输入和荷载工况定义,整个过程相较于深度学习耗时耗力。

Triple points and phase transitions of D-dimensional dyonic Ad S black holes with quasitopological electromagnetism in Einstein–Gauss–Bonnet gravity

引用

Chinese Physics B 2024年第6期33卷 272-287页

作者：牟平辉蒋青权何柯腱李国平 School of Physics and Astronomy China West Normal UniversityNanchong 637000China College of Physics Chongqing UniversityChongqing 401331China

By considering the negative cosmological constant Λ as a thermodynamic pressure, we study the thermodynamics and phase transitions of the D-dimensional dyonic Ad S black holes(BHs) with quasitopological electromagnetism in Einstein–Gauss–Bonnet(EGB) gravity. The results indicate that the small/large BH phase transition that is similar to the van der Waals(vdW) liquid/gas phase transition always exists for any spacetime dimensions. Interestingly, we then find that this BH system exhibits a more complex phase structure in 6-dimensional case that is missed in other ***, it shows for D = 6 that we observed the small/intermediate/large BH phase transitions in a specific parameter region with the triple point naturally appeared. Moreover, when the magnetic charge turned off, we still observed the small/intermediate/large BH phase transitions and triple point only in 6-dimensional spacetime, which is consistent with the previous results. However, for the dyonic Ad S BHs with quasitopological electromagnetism in Einstein–Born–Infeld(EBI) gravity, the novel phase structure composed of two separate coexistence curves observed by Li et al. [Phys. Rev. D105 104048(2022)] disappeared in EGB gravity. This implies that this novel phase structure is closely related to gravity theories, and seems to have nothing to do with the effect of quasitopological electromagnetism. In addition, it is also true that the critical exponents calculated near the critical points possess identical values as mean field theory. Finally, we conclude that these findings shall provide some deep insights into the intriguing thermodynamic properties of the dyonic Ad S BHs with quasitopological electromagnetism in EGB gravity.
