Updating Material Factors for Assessment of Historic Reinforced Concrete Bridge

Transactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2016
This paper is focused on the reliability analysis of an existing reinforced concrete bridge from 1908. The load bearing capacity is assessed in accordance with valid standards using updated partial factors and the partial factors for structural design ...

Analysis of the Anisotropic Cyclic Material Behavior of EN AW-1050A H24 Derived from Strain-Controlled Testing Using a Clip-On Extensometer and an Optical System

Crystals
Due to its good conductive properties, unalloyed (pure) aluminum, such as EN AW-1050A H24, finds new fields of application in electromobility. To optimize components, the cyclic material behavior must be understood and described precisely as a foundation

Analyzing network reliability using structural motifs

Physical Review E, 2015
This paper uses the reliability polynomial, introduced by Moore and Shannon in 1956, to analyze the effect of network structure on diffusive dynamics such as the spread of infectious disease. We exhibit a representation for the reliability polynomial in terms of what we call {\em structural motifs} that is well suited for reasoning about the effect of ...

Estimating Design Resistance of Wrought Balcony Girders

Transactions of the VŠB: Technical University of Ostrava, Civil Engineering Series, 2017
The contribution is focused on reliability of balcony girders of a Czech national heritage monument. As preliminary reliability assessment suggests insufficient resistance, a series of nondestructive tests supplemented by a single tensile test are ...

Note: Pairwise rearrangements in reliability structures

Naval Research Logistics, 1994
Summary: \textit{P. J. Boland}, \textit{F. Proschan} and \textit{Y. L. Tong} [Nav. Res. Logist. 36, No. 6, 807-815 (1989; Zbl 0685.90047)] used the notion of criticality of nodes in a coherent system to study the optimal component arrangement of reliability structures. They also provided a sufficient minimal cut (path) based criterion for verifying the
