Abstract

The paper presents a proposal for the assessment of the reliability of steel truss (both statically determinate and indeterminate) in the persistent and accidental design situation. In the analysis, a probabilistic approach was used. The global Hasofer-Lind reliability index was employed, computed in successive time steps for the whole structure, not for individual elements. The statically determinate truss was modelled as a serial system from the reliability standpoint. For the statically indeterminate truss, kinematically admissible failure mechanisms were determined by means of the examination of the singularity of the stiffness matrix of the structure, converting the truss into a geometrically variable system. For the problem thus formulated, a serial-parallel reliability model was constructed. Monitoring the reliability index in the successive minutes of the fire makes it possible to estimate the probability of the structure failure, and to decide whether the required safety level is maintained.

Abstract

Czarny Paryż [The Back Paris] is a crime novel written by Jolanta Fuchsówna, journalist and writer, and Jan Brzękowski, leading poet of the Cracow Avant-garde who lived in Paris, and serialized in the Cracow daily Ilustrowany Kurier Codzienny in 1932, but not published as a book. In this article two typescripts of the novel are analyzed and compared with the printed text, taking note of all the corrections and amendments introduced by the authors. An integral supplement to this textual study is an extract from Chapter XIII ‘A Party in the Studio of the Japanese Man’ reproduced in two versions, 1) with footnotes and modernized spelling, and 2) the original text from the typescript with all annotations.
