In this regard, the behavior of six prototype structures (with different heights and plan layouts) is investigated through nonlinear static and time history analyses, implemented in the OpenSees platform. The results of the analyses are presented in terms of the behavior of the slab-column connections and their mode of failure at different loading stages. Moreover, the global response of the buildings is discussed in terms of some parameters, such as lateral overstrength due to the gravity flat slab-column frames. According to the nonlinear static analyses, in structures in which the slab-column connections were designed only for gravity loads, the slab-column connections exhibited a punching mode of failure even in the early stages of loading. However, the punching failure was eliminated in structures in which a minimum transverse reinforcement recommended in ACI 318 (2019) was provided in the slabs at joint regions. Furthermore, despite neglecting the contribution of gravity flat slab-column frames in the lateral load resistance of the structures, a relatively significant overstrength was imposed on the structures by the gravity frames.","PeriodicalId":11416,"journal":{"name":"Earthquake Engineering and Engineering Vibration","volume":"9 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141610005","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 influence of body shape and fixed measure parameters on the seismic responses of replicas and the interaction behavior between replicas and fixed measures have been explored. Based on the results, seismic effectiveness evaluation indexes of the tie up method are proposed. Reasonable suggestions for fixed strategies are given, which provide a basis for the exhibition of delicate museum collections considering the principle of minimizing seismic responses and intervention. The analysis results show that a larger ratio of height of mass center to bottom diameter led to more intense rocking responses. Increasing the initial pretension of fishing lines was conducive to reducing the seismic responses and stress variation of the lines. Through comprehensive consideration of the interaction forces and effective securement, it is recommended to apply 20% of breaking stress as the initial pretension. For specific museum collections that cannot be effectively protected by the independent tie up method, an optimized strategy of a combination of fishing lines and fasteners is recommended.","PeriodicalId":11416,"journal":{"name":"Earthquake Engineering and Engineering Vibration","volume":"75 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141610006","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 Wangjiayan landslide, which was triggered by the Wenchuan earthquake, is a typical case in point. The Wanjiayan landslide caused many casualties and resulted in enormous property loss. This study constructs a simple surficial failure model based on the upper bound approach of three-dimensional (3D) limit analysis to evaluate the slope stability of the Wangjiayan case, while a traditional two-dimensional (2D) analysis is also conducted as a reference for comparison with the results of the 3D analysis. A quasi-static calculation is used to study the effect of the earthquake in terms of horizontal ground acceleration, while a parametric study is conducted to evaluate the critical cohesion of slopes. Rather than employing a 3D analysis, using the 2D analysis yields an underestimation regarding the safety factor. In the Wangjiayan landslide, the difference in the factors of safety between the 3D and 2D analyses can reach 20%. The sliding surface morphology as determined by the 3D method is similar to actual morphology, and the parameters of both are also compared to analyze the reliability of the proposed 3D method.","PeriodicalId":11416,"journal":{"name":"Earthquake Engineering and Engineering Vibration","volume":"27 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141610000","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}

Similar to other Latin American cities, Guadalajara is exposed to high seismic risk, with the particularity of being the largest urban settlement in Latin America built on pumice soils. Methodology has not yet been tested to characterize subsoil depths in pumice sands. Due to the questionable use of traditional geotechnical tests for the analysis of pumice soils, HVSR provides an alternative for its characterization without altering its fragile and porous structure. In this work, resonance frequency (F0) and peak amplitude (A0) are used to constrain the depth of the major impedance contrast that represents the interface between bedrock and pumice soil. Results were compared with borehole depths and other available geotechnical and geophysical data and show good agreement. One of the profiles estimated on the riverbanks that cross the city, reveals different subsoil thickness that could have an impact on different site responses on riverine areas to an eventual earthquake. Government and academic efforts are combined in this work to characterize depth sediments, an important parameter that impacts the regulations for construction in the city.","PeriodicalId":11416,"journal":{"name":"Earthquake Engineering and Engineering Vibration","volume":"10 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141614729","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}

As the basis of the co-working ability of steel plate and concrete, the bonding status plays an essential role in guaranteeing the structural performance of SCCS. Accordingly, efficient non-destructive testing (NDT) on interfacial debondings in SCCS has become a prominent research area. Multi-channel analysis of surface waves (MASW) has been validated as an effective NDT technique for interfacial debonding detection for SCCS. However, the feasibility of MASW must be validated using experimental measurements. This study establishes a high-frequency data synchronous acquisition system with 32 channels to perform comparative verification experiments in depth. First, the current sensing approaches for high-frequency vibration and stress waves are summarized. Secondly, three types of contact sensors, namely, piezoelectric lead-zirconate-titanate (PZT) patches, accelerometers, and ultrasonic transducers, are selected for MASW measurement. Then, the selection and optimization of the force hammer head are performed. Comparative experiments are carried out for the optimal selection of ultrasonic transducers, PZT patches, and accelerometers for MASW measurement. In addition, the influence of different pasting methods on the output signal of the sensor array is discussed. Experimental results indicate that optimized PZT patches, acceleration sensors, and ultrasonic transducers can provide efficient data acquisition for MASW-based non-destructive experiments. The research findings in this study lay a solid foundation for analyzing the recognition accuracy of contact MASW measurement using different sensor arrays.","PeriodicalId":11416,"journal":{"name":"Earthquake Engineering and Engineering Vibration","volume":"76 1","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140623778","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}
