Kouroussis","doi":"10.7712/120119.7212.19125","DOIUrl":"https://doi.org/10.7712/120119.7212.19125","url":null,"abstract":"In the railway domain, studies have been undertaken on the attenuation of vibrations transmitted to the vehicle in order to improve the comfort of the passengers. However, a slight variation in the stiffness and damping characteristics of the train constitutive parts can considerably change the amount of energy transmitted to the soil in terms of vibrations. To predict those ground-borne vibrations generated by the vehicle moving along the track that could affect or disturb the surrounding environment, a relevant option would be to build a numerical model that simulates the passage of a vehicle on a track by coupling a multibody modeling of the train with a finite element modeling of the soil using co-simulation techniques. However the location where the model has to be split remains uncertain and then the border between the multibody and the finite element parts must be determined. The aim of this paper is to emphasize the possibility to perform co-simulation between two or more subsystems using an in-house C++ library package called EasyDyn. Using its co-simulation capabilities, the recoupling of a vehicle, that can be modeled using the minimal coordinates approach in multibody systems and a track modeled using a finite element representation of the rail and sleepers, will be discussed.","PeriodicalId":414988,"journal":{"name":"Proceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129420616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Giresini","doi":"10.7712/120119.6945.19268","DOIUrl":"https://doi.org/10.7712/120119.6945.19268","url":null,"abstract":"Although still poorly investigated, the failure of corners is a frequent event in masonry buildings and clearly recognizable in the aftermath of a seismic event. It is characterized by the formation of a masonry wedge, mainly due to the thrust of roof elements in addition to inertial forces, and it generally involves rocking-sliding motion along the cracks on the interlocked orthogonal walls. In this paper, the case study of the corner failure in a masonry building located in Visso (Italy) is analyzed. The building was seriously damaged by the seismic events of August 24th, 2016 and October 26th and 30th, 2016. In particular, one of the free corners at the first storey completely collapsed. The seismic capacity with respect to the onset of this failure mode is analyzed by means of a refined macro-block model and by adopting the linear kinematic approach of limit analysis, accounting for frictional resistances and the thrust of roof elements. The key aspect of the proposed approach is the introduction of a criterion to evaluate the contribution of the actual frictional resistances depending on the inclination angles of the crack lines. Moreover, the loads transmitted from the roof to the walls are defined by assuming simplified static conditions according to the typology of the hipped roof. Lastly, the achieved results are compared to the seismic demand obtained by adopting the Italian Technical Standards for Constructions, both the earlier version (2008) and the current one (2018), together with that obtained using in situ recorded floor accelerations.","PeriodicalId":414988,"journal":{"name":"Proceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015)","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123980977","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abbas","doi":"10.7712/120119.7203.19035","DOIUrl":"https://doi.org/10.7712/120119.7203.19035","url":null,"abstract":"This work examines experimentally and numerically the influence of steel fibre reinforcement on lightweight aggregate concrete (LWAC). The replacement of conventional aggregates with recycled lightweight ones has several benefits such as reducing the mass of the structure lead-ing to more economical designs (also beneficial under earthquake loading). The experimental project showed that it was possible to produce higher strength to weight ratio of LWAC com-pared to normal weight aggregate concrete (NWAC) as dry densities were approximately 700 Kg/m3 lower for identical characteristic compressive strengths between 40MPa and 30MPa. This could lead to savings in materials, construction and transportation costs making it espe-cially useful and economical for long-span and seismic-resistant structures. Conversely, LWAC is noted for its highly brittle nature due to its associated weak aggregate interlock mechanism which can be typically compensated for by increasing shear reinforcement and dowel action by means of adding higher reinforcement ratios. Nonetheless, this creates sever-al challenges in construction such as congestion of reinforcement in critical regions as well as increased dead loads which render LWAC use counterproductive. Thus, steel fibre rein-forcement emerges as a promising solution where partial or total substitution of conventional transverse reinforcement could become a possibility. This project carries out examination of the effectiveness of hooked-end steel fibre reinforcement with fibre volume fractions of Vf = 1% and Vf = 2%. The experimental investigation includes the study of direct uniaxial com-pression and tension (unique pullout test) and indirect splitting and flexural tensile tests. Moreover, a nonlinear finite element study has been carried out using ABAQUS to model the experiments using CDP. Currently, there is no international standards or design guidelines for steel fibre reinforced lightweight concrete (SFRLC). This project will help address that and lead to sustainable and innovative seismic design solutions in the future.","PeriodicalId":414988,"journal":{"name":"Proceedings of the 7th International Conference on Computational Methods in Structural Dynamics and Earthquake Engineering (COMPDYN 2015)","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124504920","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
