Analysis of deformations of the skylight construction at the Main Hall of the Warsaw University of Technology

The paper presents technology and results of measurements of the steel construction of the skylight of the Main Hall of the Warsaw University of Technology. The new version of the automated measuring system has been used for measurements. This system is based on Leica TCRP1201+ total station and the TCcalc1200 software application, developed by the author, which operates on a laptop computer connected with the total station by the wire. Two test measurements were performed. Each of them consisted of cyclic measurement using the polar method, from one station; points located on the skylight construction, as well as control points located on concrete, bearing poles, were successively measured. Besides geometrical values (such as Hz, V angles and the slope distance D), the changes of temperature and atmospheric pressure, were also recorded. Processed results of measurements contained information concerning the behaviour of the skylight; asymmetry of horizontal displacements with respect to the X axis have been proved. Changes of parameters of the instrument telescope and changes of the instrument orientation were also stated; they were connected with changes of the temperature. The most important results of works have been presented in the form of diagrams.

Autorzy artykułu przeprowadzili badania empiryczne mające na celu ocenę możliwości wykorzystania wyników pomiaru skanerem laserowym ScanStation firmy Leica w badaniu przemieszczeń i odkształceń obiektów budowlanych. Analiza oparta była na eksperymencie badawczym polegającym na wyznaczeniu najmniejszej wartości przesunięć, jaka jest możliwa do zarejestrowania tym instrumentem, wzdłuż osi obranego układu współrzędnych. Przebieg oraz wyniki badań testowych poprzedzono opisem instrumentu oraz charakterystyką wyników pomiaru.

The authors of this article did empirical researches, which have been showing the possibilities of using results of measurement from laser scanner ScanStation from Leica Geosystems to research deformations of building structures. The analysis was based on a scientific experiment depends on determination the minimum value of displacement, which is possible to register by this instrument, along axis from preferred coordinate system. The follow of the tests researches and its results was preceded the description of instrument and the results of measurement specification.
