Analysis of a new design of window installation in the facade system Qbiss one by using the finite element method

摘要

The thesis presents the results of numerical analyses that are part of a study on suitability of a new method of window installation in the façade system Qbiss One, produced by the company Trimo d.d. The main novelties of the new system are the removal of the longitudinal reinforcement pipes and a modified design of the window and façade element holder. In numerical analyses we discussed the part of the façade system which we named the panel-window-panel system. For its plot the CATIA programme was used and for the analysis according to the method of finite elements, we used the programme ANSYS where we took into account the symmetry of the system under consideration. Alludthe details of Qbiss One panels and the windows have been modelled and for that we used 3d finite elements for solid body and shell finite elements. Both types of finite elements were linked together with contact finite elements. We made linear elastic analyses of the effects of the wind and temperature changes, the stationary thermal analysis, modal analysis and buckling analysis, as well as geometrical and material nonlinear analysis, both for the effect of wind. Based on the calculated results we obtained information on the acceptability of the proposed new method of window installation in the façade system Qbiss One. It turns out that with some additions, the new method could become a perfectly acceptable replacement of the existing window installation method.
