To address the inadequacies in the current definition and description of seismic performance for prefabricated segmental tunnels, this study focuses on the division of structural performance levels for shield tunnel structures and determines the deformation limit values for their seismic and waterproof performance objectives. The performance objectives of the prefabricated segmental tunnels were divided into five levels: basic intact, operational, repairable, medium-repairable, and severely damaged. To obtain quantifiable performance indicators for prefabricated segmental tunnels that correspond to these performance objectives, this study investigated two adjacent ring segments of 19 sealed roof blocks at different positions based on four classic sites. Finite element models with refined details were utilized for the pushover analysis to obtain the capacity curves for the segment structures. Based on the relationship between the capacity curves and the performance objectives, the limit values of the diameter change rates for each case were determined using geometric plotting methods. The limit values of the diameter change rates for the prefabricated segmental tunnels corresponding to the five performance levels were determined to be 1/1850, 1/320, 1/180, 1/160, and 1/130. Finally, an index system was established for the seismic performance of prefabricated segmental tunnels. The proposed angle limits provide foundational guidance for the seismic design of prefabricated segmental tunnels.</div></div>","PeriodicalId":49502,"journal":{"name":"Soil Dynamics and Earthquake Engineering","volume":"195 ","pages":"Article 109443"},"PeriodicalIF":4.2,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834186","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}

However, the understanding of seismic wave propagation and ground motion attenuations, particularly considering source-path-site effects, remains limited, becoming a key bottleneck in the seismic design of WTs. To address this, this paper assesses the seismic performance of WTs by analyzing the combined effects of seismic source characteristics, wave propagation paths, and local site conditions, and proposes a novel method for assess site effects on WTs in mountainous regions using scenario-based earthquake simulations. In the methodology, the frequency-wavenumber (FK) method is employed for the semi-analytical solution of deep crustal Green's functions, the spectral element (SE) method for efficient large-scale wave field simulations, and the finite element (FE) method for detailed structural modeling of WT responses. The resulting FK-SE-FE approach enables a full-process physics-based simulation from fault rupture to the structural response. Using the Jishishan <em>M</em>_S6.2 earthquake as a case study, near-fault ground motions are synthesized to evaluate the influence of mountainous' terrain on the seismic response of WTs. Results indicate that the presence of the mountain during seismic wave propagation significantly increased the overall seismic response of the structure, with the tower-top displacement of the mountain-top WT being amplified by up to 2.56 times compared to the mountain base. Additionally, the continuous ridge effect led to an increased peak ground acceleration at the mountain base, but the overall amplification effect is more pronounced at the mountain top. These findings provide valuable insights for enhancing seismic design codes and developing risk mitigation strategies for WTs in complex terrains.</div></div>","PeriodicalId":49502,"journal":{"name":"Soil Dynamics and Earthquake Engineering","volume":"195 ","pages":"Article 109442"},"PeriodicalIF":4.2,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143834279","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}

The BBSDS is designed to dissipate energy and limit displacements through a slip-and-deformation mechanism. The mechanical properties of the BBSDS are validated through theoretical analysis and numerical simulations. Additionally, a simplified mechanical model is developed. Nonlinear analysis models of simply supported bridges are established for four working conditions: without shear keys, with concrete shear keys, with steel shear keys, and with BBSDS. The base shear, base moment, relative displacement between the pier and girder, residual displacement, and bearing displacement are compared. The results show that a simply supported bridge with BBSDS effectively limits the displacement of the girder without significantly increasing the base response of the pier. Notably, the BBSDS also reduces the residual displacement and bearing displacement, thereby mitigating bearing failure. Parametric analyses were conducted on the slip stiffness, limit stiffness, and initial gap of the BBSDS. The results indicated that an increase in slip stiffness or limit stiffness effectively reduced the residual displacement; however, it may concurrently elevate the base response of the pier. The increase in the initial gap reduced the base response of the pier, but increased the relative displacement between the pier and beam, as well as the residual displacement.

However, several researchers have pointed out that the excess pore water pressure may not reach confining pressure at some certain conditions, and the cycle numbers reaching liquefaction obtained by adopting two criteria for calcareous sand specimens are inconsistent, which may lead to overestimation or underestimation of the liquefaction resistance of calcareous sand. Therefore, this study introduces a parameter with physical meaning, secant shear modulus to evaluate the liquefaction potential of soil. To do that, a series of undrained shear tests were conducted on three types of sand. Firstly, the experimental results demonstrated that the difference in cycle numbers to liquefaction obtained by the two criteria increases with the increase of relative density. In addition, the study found that the degradation law of secant shear modulus with the number of cycles is not affected by loading conditions, initial state of soil, and soil type. On this basis, based on the relationship between secant shear modulus gradient and pore pressure ratio, it is highlighted that the liquefaction process can be quantitatively divided into three stages and the moment of liquefaction triggering can be correctly identified. Finally, the proposed liquefaction criterion is compared with widely used traditional criteria and latest apparent viscosity-based criterion, and the results showed that the liquefaction resistance obtained by the proposed criterion was more conservative, which benefits for reducing the occurrence of large strain development.</div></div>","PeriodicalId":49502,"journal":{"name":"Soil Dynamics and Earthquake Engineering","volume":"195 ","pages":"Article 109439"},"PeriodicalIF":4.2,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143815085","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}
