Investigation of the Reliability of Reinforced Concrete Overpasses of a Road Overpass
Journal Title: Современное промышленное и гражданское строительство - Year 2017, Vol 13, Issue 2
Abstract
The scientific task of ensuring the reliability of road bridges is formulated in the article. Reinforced concrete regulation of bridges reliability in normative documents is analyzed. A model is proposed to forecast reliability of operated span structures of road bridges. This model is based on the actual reliability of bent elements at the time of technical survey. It is possible to determine the initial reliability, predict the change in reliability over time, and determine the remaining resource when reliability required is achieved. The requirements of normative documents are analyzed. Recommendations are given to designate the design value of safety characteristics of the bent elements of road bridges span structures.
