To predict the axial-flexure-shear behaviors of such hollow piers, an innovative approach named Axial-Flexure-Shear-Interaction-Membrane-Beam-Truss-Element-Model (AFSI-MBTEM) is developed. In the AFSI-MBTEM, the RC hollow pier is discretized into membrane elements, beam elements, and truss elements. The bi-scalar damage-plasticity concrete model is used in the membrane elements to consider the compression-softening effect and the degradations of strength and stiffness. <em>Concrete01</em> and <em>ReinforcingSteel</em> are adopted as uniaxial materials for beam-column elements and truss elements. The axial-flexure and axial-shear behaviors are coupled through the multi-dimensional material and the integration of multiple element types. The numerical approximation of the AFSI-MBTEM for rectangular and circular RC hollow piers is presented, and it is implemented in OpenSees. A series of RC thin-walled hollow piers with different failure modes under cyclic loading were collected for validation. The predictions against experimental results indicate that the AFSI-MBTEM captures the cyclic responses of RC hollow piers with excellent accuracy, convergence, and efficiency. However, overestimations of yield plateau and energy dissipation, along with sudden drops at large ductility, are observed in simulations using the flexure model. The dynamic responses of the full-scale hollow piers under 223 pulse-like motions further demonstrate the superiority of the AFSI-MBTEM. Meanwhile, the flexure model underestimates their dynamic responses due to the enhanced energy dissipation capacity and the neglect of shear effects.</div></div>","PeriodicalId":49502,"journal":{"name":"Soil Dynamics and Earthquake Engineering","volume":"195 ","pages":"Article 109375"},"PeriodicalIF":4.2,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143705010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By integrating the Crested Porcupine Optimizer (CPO) and Variational Mode Decomposition-Hilbert Transform (VMD-HT), this paper establishes the CPO-VMD-HT algorithm for seismic signals for the first time and puts forward an identification method for the seismic damage mechanism based on the marginal spectrum. The effectiveness of this method is validated through large-scale shaking table experiments conducted on a typical embankment slope. The results demonstrate that the amplification effect of the embankment slope acceleration is mainly triggered by the mutual superposition of the 0–20 Hz seismic energy and the 45–55 Hz resonant energy. When seismic excitation triggers slope resonance, the acceleration amplification coefficient <em>β</em> at the embankment decreases from 2.16 to 1.26. When the input peak ground acceleration (PGA) is 0.5 g, the second highest value area of seismic energy emerges at the left toe of the embankment, with the peak marginal spectrum amplitude (PMSA) reaching 86.27. The first and second plastic zones gradually coalesce and form a sliding surface, driving the embankment slope into the critical state of instability. Through an analysis of the PMSA, differences in the Hilbert energy distribution within various layers of the embankment slope can be discerned, elucidating the development of shear bands and the dynamic failure mechanisms within the slope. Conducted from an energy propagation perspective, this paper clarifies the acceleration amplification effect and seismic failure mechanisms of embankment slopes. It is thus a crucial reference for the safety risk perception and accurate trend prediction of railway slopes in earthquake-prone areas.</div></div>","PeriodicalId":49502,"journal":{"name":"Soil Dynamics and Earthquake Engineering","volume":"195 ","pages":"Article 109396"},"PeriodicalIF":4.2,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143697953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, this study developed a numerical method for analyzing the dynamic response of suction bucket foundations in sandy soils under such combined loading conditions. Through numerical simulations across various scenarios, this research investigates the influence of key factors such as seismic intensity, spectral characteristics, as well as the magnitude and direction of tensile loads on the seismic response of suction buckets. The results revealed that the strong earthquake may cause the suction bucket foundation of floating wind turbines to fail due to excessive vertical upward displacement. This can be attributed to that the accumulation of excess pore water pressure reduces the normal effective stress on the outer wall of bucket, and consequently decreases the frictional resistance of bucket-soil interface. Additionally, the above factors significantly influence both the vertical displacement of the suction bucket and the development of pore pressure in the surrounding soil.
