As the demand for energy continues to grow, new frontiers in energy exploration will emerge - some with the potential for induced seismicity. Thus, there is a clear need for a source-agnostic seismic risk protocol that can be applied to any activity or region. This study outlines one such implementation that uses scenario earthquakes to produce a priori risk thresholds that can be referenced against current seismicity levels on an ongoing basis. Our framework is designed to inform regulatory decisions by considering the consequences of earthquake scenarios on the population and the built environment, together with simplified forecasts of the next largest magnitude. The proposed framework can tackle both the screening process needed for permitting purposes and serve as a risk management plan during operations.</p></div>","PeriodicalId":9364,"journal":{"name":"Bulletin of Earthquake Engineering","volume":"23 4","pages":"1325 - 1347"},"PeriodicalIF":3.8,"publicationDate":"2025-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10518-024-02088-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental results indicated that the degradation in the shear strength carried by the concrete (<i>V</i>_<i>c</i>) controlled the overall shear strength behavior of the test beams. The <i>V</i>_<i>c</i> of the test beams with shear span ratios greater than 1.5 eventually reduced to zero owing to the development of shear cracks. A calculation method for predicting the ASFI behavior of RC members was proposed to predict the lateral behavior without numerous mathematical iterations, which accounted for deformations due to flexure, steel-bond slip, and shear. An analytical model was derived to calculate the nominal shear strength using the shear friction mechanism and the Mohr–Coulomb failure criterion. Compared to the models currently proposed in design provisions, this model exhibited better alignment with the experimental results. A new model describing the degradation of shear strength due to shear cracks was also proposed, which incorporated the effect of the longitudinal rebar bond strength on the drift at which the nominal shear strength begins to deteriorate. Comparisons between the predicted and experimental results of RC members with different structural variables indicated that the ASFI calculation program and shear strength model accurately predicted the lateral behavior, shear failure, and post-failure behavior.</p></div>","PeriodicalId":9364,"journal":{"name":"Bulletin of Earthquake Engineering","volume":"23 5","pages":"2047 - 2081"},"PeriodicalIF":3.8,"publicationDate":"2025-02-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143830755","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}

Thus, seismic upgrading techniques and advanced design approaches are continuously proposed for a better structural performance, of which the externally-attached sub-system is an effective strategy. The authors formerly proposed a high-performance external sub-system for seismic upgrading, namely, the self-centering precast bolt-connected steel-plate reinforced concrete (SC-PBSPC) buckling-restrained braced frame (BRBF), and experiments have been performed to validate its feasibility and superiority. In this paper, a novel design framework for the external SC-PBSPC BRBF sub-system considering combined demand-capacity uncertainties under nonstationary excitation is further investigated. The novel design framework is derived from the incremental dynamic analysis and capacity spectrum method (IDA-CSM), and it is an organic integration and an effective improvement for a better upgrading solution. The proposed stochastic IDA-CSM based design framework consists of three stages (i.e., the performance evaluation before upgrading, the component design of sub-systems, and the performance verification after upgrading) and two primary analyzing approaches [i.e., the stochastic pushover analysis (POA) for capacity-demand spectra curves, and the stochastic IDA for fragility curves]. During the procedure, the design factors are regarded to be stochastic variables and multiple uncertainties are incorporated for a probabilistic estimation, both before and after upgrading, respectively. An application example via a three-dimensional frame building is also implemented to verify the feasibility of the design framework, and multiple uncertainties provide a probabilistic prediction of the upgraded behavior in a more realistic way. The proposed research serves as a reference for the related design exploration and plays a key role for further probabilistic work from a macro perspective.</p></div>","PeriodicalId":9364,"journal":{"name":"Bulletin of Earthquake Engineering","volume":"23 4","pages":"1707 - 1735"},"PeriodicalIF":3.8,"publicationDate":"2025-02-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638485","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, uncertainties persist in attributing some past destructive earthquakes to seismogenic sources, as in the case of the 1706 Maiella earthquake (Mw 6.8, Abruzzi region). This study comprehensively assesses competing source hypotheses derived from the literature and uses geological and geophysical data to constrain their possible fault geometry. Employing a 3D seismogenic source model approach, we rigorously analyze the earthquake-fault association, assessing the misfit between the simulated site intensities and the macroseismic values estimated from the historical accounts. Our findings highlight the complexities in determining a reliable source for the 1706 earthquake. Finally, the best-fit source model was adopted to produce ground motion predictions regarding Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV), and macroseismic intensity, including site effects, coupling the ground motion model (GMM-ITA18; Lanzano et al. 2019) and the ground motion intensity conversion equation (GMICE; Gomez Capera et al., 2020). The presented outcomes possibly unveil the shaking scenario that occurred in the past and perhaps in the future.

Studying the influence of the post-yield stiffness ratio on the maximum and residual displacements of structures under long-period ground motions is crucial for post-earthquake repairs. This paper selected 25 OGM, 25 FLGM, and 25 NPGM to calculate the elastic-plastic displacement response of single degree of freedom (SDOF) systems, analyzing the influence of ground motion types, post-yield stiffness ratio, natural periods, and strength reduction coefficients on normalized elastic-plastic displacement. And the influence of design parameters and loading paths on the post-yield stiffness ratio of components was analyzed by finite element analysis based on the method of calculating the post-yield stiffness ratio of components. The results show that the normalized maximum displacement decreases with the increase of the period, the increase of post-yield stiffness ratio and the decrease of strength reduction coefficient. Nevertheless, the variation degree of the normalized maximum displacement is distinguishing under different ground motions. The normalized residual displacement of SDOF system under the NPGM is the most significant and the variation of normalized residual displacement with post-yield stiffness ratio, strength reduction coefficient and natural period is different under different ground motions. Moreover, post-yield stiffness ratio of components is significantly influenced by design parameters and loading path.</p></div>","PeriodicalId":9364,"journal":{"name":"Bulletin of Earthquake Engineering","volume":"23 4","pages":"1541 - 1560"},"PeriodicalIF":3.8,"publicationDate":"2025-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638404","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 objective of this study is to investigate the characteristics of near-fault ground motions observed in the earthquake sequence. To this end, the ground motion intensity measures are firstly compared with existing models; it is shown that PGA and spectral accelerations from both the non-pulse-like and the pulse-like motions are overall captured by the Zhao et al.

Subsequently, the velocity pulses in near-fault ground motions are not only quantitatively identified, but are also parameterized using the progressive iterative approach. The identified pulses are then empirically categorized into two groups of records with different causative effects according to the criterion of whether or not non-zero displacements could be visually inspected at the end of the integrated pulse displacement traces. Pulse-like ground motions containing baseline offset are also corrected, and final permanent displacements due to fling-step effects are accordingly derived. To determine the orientations at which the strongest pulses can be observed, two different approaches are employed. It is revealed that the indirect method by seeking the orientation of the maximum PGV appears to be not reliable if it is to find the strongest pulse, at least with respect to the 2023 Türkiye earthquake sequence.</p></div>","PeriodicalId":9364,"journal":{"name":"Bulletin of Earthquake Engineering","volume":"23 4","pages":"1349 - 1369"},"PeriodicalIF":3.8,"publicationDate":"2025-02-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143638274","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}

Despite its relatively low magnitude, the earthquake caused significant damage, resulting in 154 deaths and the collapse of over 26,557 houses. This underscores the critical need for post-earthquake reconnaissance to identify vulnerabilities and improve mitigation strategies before more severe events occur. Recognizing this importance, a detailed reconnaissance was conducted from November 6 to 9, 2023, focusing on the geotechnical impact of the earthquake.

The study also explores the potential triggering mechanisms for the rock fall and discusses possible remedial techniques. Additionally, the influence of the local site effect on the extent of damage was examined. Remote sensing techniques were employed to detect post-earthquake ground patterns and land use changes using Sentinel-1 and Sentinel-2 images, respectively. The Sentinel-1 images were analyzed using the persistent scattering interferometric synthetic aperture radar (PS-InSAR)-based method, and the Sentinel-2 images were analyzed via the Google Earth Engine (GEE).
