REVISITING DURABILITY OF BRIDGE SOLID PIERS
https://doi.org/10.31675/1607-1859-2018-20-5-185-197
Abstract
The paper presents data on the prevalence and service life of solid piers of railroad bridges of the Russian Railways. The dynamics of solid pier damages, the development of normative documents on assessing their technical conditions and durability, and methods of assessing the residual life of bridge structures are shown herein. Information on the threshold values of failure is also given. The residual life of the intermediate masonry support is analyzed and estimated using two standard techniques. Their similarities and differences are determined and their limitations are compared. Proposals are made to clarify the damage parameters described in the current normative document for assessing the technical condition of railway structures. For statistical data processing in relation to bridge damages and prediction of their development, a model is proposed on the basis of semi- Markovian process. Possible data sources for constructing such a model are indicated. An alternative model for estimating the reliability of bridge structures is shown.
