Original Abstract

The paper deals with the diagnostics of steel roof structures of two winter stadiums built in 7th decade of the past century. The necessity of the diagnostics has been given by the requirement to the evaluation design of these structures, which has been caused by the new situation in the field of the loadings given by the validity of the European Standards in the Czech Republic from 2010 year. Due to these changes in the normative rules, in practice the existing structures are gradually subjected to the evaluation design and depending on its results to the strengthening or reconstruction, respectively. The paper is focused on the diagnostics of two steel roof structures: (i) the spatial truss grid and (ii) the member structure composed of the plane truss main girders, purlins and bracings. The diagnostics of these structures consisted of two parts: (i) diagnostics in situ oriented to the verification of the actual dimensions of the structural members and (ii) laboratory diagnostics oriented to the determination and evaluation of the actual material properties of used steel. For the solution the following main testing methods have been used: non-destructive methods for the diagnostics in situ and destructive methods for the laboratory testing. For the verification of structural member dimensions (thickness of hollow members) in situ the ultrasound methods have been used. For the indicative determination of steel strength in situ the modified methods based on the determination of the Rockwell hardness have been used. For the laboratory determination of steel properties the destructive methods based on the tensile tests of the specimens taken from the actual structure have been used. The paper presents the results obtained using these testing methods and their evaluation from the viewpoint of the usage for the subsequent static assessment and design evaluation of the existing structures.
