Abstract
Recommended reliability levels and their adequate partial safety factors can be found in Eurocodes only for design of new structures and bridges. Modified reliability levels and partial safety factors for verifying bridge structures for their remaining lifetime were determined by theory of reliability at Department of Structures and Bridges at Civil Engineering Faculty, University of Žilina. This paper is focused on verification of modified partial safety factors of materials and load effects using calibration.
Highlights
Each building and civil engineer should ensure that the design of the building and civil structures is reliable, in this case the reliability of the bridge structures
We consider the probability of failurefree operation during the operation, which is called as the reliability level and is denoted as Pr
The modified reliability levels given by the reliability index βt or by the probability of failure Pft and the corresponding partial safety factors of material properties and load effects were determined in the frame of the research activities of the Department of Structures and Bridges of University of Žilina [6, 7, 8]
Summary
Each building and civil engineer should ensure that the design of the building and civil structures is reliable, in this case the reliability of the bridge structures. The reliability is the ability of the construction to perform the required functions to which it was designed under normal conditions and maintenance without any necessary repairs and reconstructions throughout its design lifetime Td. For newly designed structures, the decisive role of the properties, as load-bearing capacity, safety, serviceability, durability and robustness, which are closely related to each other, are crucial to ensuring the required reliability. We consider the probability of failurefree operation during the operation, which is called as the reliability level and is denoted as Pr. The opposite value of the reliability level is the failure probability Pf and it expresses the probability of occurrence of a failure over the lifetime of the structure and the following should valid. Any building construction is not completely safe and reliable, because its resistance and load are affected by uncertainties that can be of different character
