In this article, in a spatial setting, the modeling technique for a reinforced concrete pile immersed in the soil array under the seismic load action has been considered. Modeling of the “pile-soil mass” system elements is performed by the volumetric finite elements. The calculation includes the shock-absorbing properties of the soil mass model (“transparent boundaries”). A comparison of the proposed methodology with the known solutions has been performed. The prospects of further development and practical application of the pile operation proposed model together with the soil under the seismic load action has been given.
The tasks of restoring and ensuring the normalized parameters of the operational qualities for building structures, as well as their further safe operation in the development of capital repair and reconstruction projects, in most cases include the replacement of existing heavy coating structures with alternative lightweight ones that meet the regulated modern standards.
The article presents the studies’ results on the safety characteristics of the most damaged load-bearing structures in a monolithic reinforced concrete building. Reliability assessment was carried out at the stage of putting the building into operation. The analysis of the numerical reliability characteristics is carried out taking into account design and actually implemented strength parameters of the considered structures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
