Właściwa ocena stateczności ogólnej elementu oraz prawidłowe wyznaczenie siły krytycznej i nośności z uwagi na wyboczenie prętów poddanych działaniu osiowej siły ściskającej decydują o poprawnym zaprojektowaniu ustroju prętowego. Opisane zagadnienia związane są z projektowaniem prętów ściskanych osiowo według Eurokodu 9, wykonanych z kształtowników aluminiowych. Prezentowany artykuł zwraca uwagę na różnice wynikające z niewłaściwego stosowania programów do wymiarowania konstrukcji aluminiowych w wypadkach, gdy programy nie zawierają procedur Eurokodu 9, a jedynie bazę danych materiałowych wyrobów aluminiowych.

Adequate assessment of general stability of the element as well as appropriate determination of a critical force and load-bearing capacity due to buckling of bars subject to the impact of axial compressing force determine the appropriate designing of the bar system. The issues described in the article are connected with designing of axially compressed bars according to eurocode 9, made using aluminium shape sections. The article pays attention to the differences resulting from improper use of software for sizing aluminium constructions in cases where programmes do not include eurocode 9 procedures, and only a material database of aluminium products.
The aim of the article is taking a closer look at the problems concerning technical condition assessment with regard to correctness of project goals of structures metal-glass facade. Made is reference to the manner of their execution and proper functioning. The issue of accordance to good engineering practice of adapting changes in the system and adjusting the fitted solutions as reccomended by the producers. Above mentioned issues were dealt with given an example of high-rise building with applied curtain wall and a residential building where a filling structure is mounted.
