The waiting room and bath building is one of the two preserved industrial facilities of the former Gliwice Mine. It was built in the first years of the 20thcentury and fulfilled its function till mine liquidation in 2000. It was overhauled and modernized in 2005-2008 and currently fulfills a new function. The paper presents a summarized history of the Gliwice Mine, a detailed description of the building structure, its technical condition before the overhaul and problems encountered during the adaptation works. It also briefly indicates the causes of the observed damage as well as describes the scope of the basic modernization works related to the new function of the building as an education and office facility. Moreover, it presents the manner of conducting the overhaul and modernization works leading to restoration of the full utility values in the new function.

Effect Of Structure

Продемонстрирована возможность применения волоконно-оптической системы на основе многоканального адаптивного голографического интерферометра для задач неразрушающей диагностики. С помощью системы выполнены детектирование и реконструкция слабого акустического поля, сформированного внутри плиты из конструкционного материала, имеющей неоднородную структуру. На основе результатов томографической реконструкции акустического поля показано влияние неоднородности на суперпозицию акустического поля. In this paper, the possibility of using fiber-optical system based on a multi-channel adaptive holographic interferometer in the problem of non-destructive diagnostics is demonstrated. The detection and reconstruction of a weak acoustic field formed inside the plate from a structural material having a structure defect has been performed. Based on the results of tomographic reconstruction of the acoustic field, the effect of structure defect on the superposition of the acoustic field inside plate is shown.

The assessment of the technical condition of the structure in industrial facilities is sometimes very difficult, even for experienced construction specialists. First, this applies to facilities in which there are quite specific cubature constructions, as objects located in the coal mine facility, or coal-fired CHP plants. In the case of energy plants, such a typical construction that causes the most problems when assessing the technical condition is coal or fine coal storage tank usually in the form of bunker batteries supplying power boilers. In practice, access to the interior of such bunkers is possible only when the power unit is put out of service (boiler extinguish) in order to repair, upgrade or expand it. In presented paper on the example of two coal bunkers (from a battery consisting of four such constructions) of one of the power plants located in southern Poland, the authors want to present and discuss some specific problems that occurred in the assessment and analysis of the technical condition of this type of specific industrial structure.

The article deals with the issues related to the assessment of the technical condition of structural elements, taking into account the stages of engineering research, design and installation. The importance of the topic under consideration is due to a large number of accidents at civil and industrial facilities that occur before the exhaustion of the bearing capacity. The analysis of the object (the metal frame of industrial buildings) is carried out on the basis of project documentation, data obtained by a full-scale survey, visual and instrumental control, numerical methods of research. The qualitative and quantitative parameters of the capital construction object necessary for assessing the technical condition are presented. They include design schemes of frame structures, materials, their characteristics, defects and parameters. The study shows the importance of comprehensive assessment of capital construction facilities in terms of constructive safety. Identification of errors at each stage of construction allows to prevent emergencies that lead to the destruction of the load-bearing system and to develop measures to establish the possibility (impossibility) of repair or reconstruction
