Glass is a material commonly used in construction. The development of technology related to it, and the increase in knowledge concerning its mechanical and strength properties offer opportunities for glass to be applied as a structural material. The advancement in glass structures, methods for their design, as well as guidelines and standards in this fields are being developed in parallel. This article describes the main assumptions contained in the German TRxV guidelines, the series of German DIN 18008 standards, and the European EN 16612, and EN 16613 standard. Moreover, the following article presents the concept of structural glass design included in the draft pre-standard prCEN/TS 19100, which provides the basis for the formulation of the European standard Eurocode 10. According to this pre-standard, structural elements of glass will be verified in four limit states, depending on the Limit State Scenario (LSS). Apart from the classic limit states, i.e., the ultimate limit state (ULS), and the serviceability limit state (SLS), it is also assumed to introduce a fracture limit state (FLS), and post-fracture limit state (PFLS). The article also addresses the issue of laminated glass working in structural elements. Depending on the coupling between the glass panes and the polymer or ionomer interlayers, laminated glass can be divided into complete coupled or uncoupled, and can work in intermediate situations. The methods for determining the effective thickness contained in European standards and guidelines are discussed in this article.

Szkło jest materiałem powszechnie stosowanym w budownictwie. Rozwój jego technologii oraz wzrost wiedzy dotyczącej właściwości mechanicznych i wytrzymałościowych sprzyja również możliwościom stosowania szkła jako materiału konstrukcyjnego. Konstrukcyjne zastosowanie szkła jest szczególnie istotne dla kształtowania rozwiązań architektonicznych, w których transparentność stanowi szczególną cechę estetyczną. Wraz z rozwojem konstrukcji szklanych są opracowywane metody ich projektowania oraz wytyczne i normy w tym zakresie. W artykule scharakteryzowano podstawowe właściwości szkła jako materiału konstrukcyjnego. Ponadto omówiono główne założenia wytycznych niemieckich TRxV, serii niemieckich norm DIN 18008 oraz norm europejskich (mających również status polskich norm) PN-EN 16612 wraz z EN 16613. Artykuł przedstawia także koncepcję projektowania szkła konstrukcyjnego zawartą w projekcie normy CEN/TS 19100, która stanowi podstawę opracowania zharmonizowanej normy Europejskiej - Eurokodu 10 dotyczącego projektowania konstrukcji szklanych. Zgodnie z tą prenormą szklane elementy konstrukcyjne będą weryfikowane ze względu na ich bezpieczeństwo w oparciu o cztery stany graniczne w zależności od tzw. klasy konsekwencji pęknięć. Oprócz klasycznych stanów granicznych, tj. stanu granicznego nośności i stanu granicznego użytkowalności, zakłada się również wprowadzenie stanu granicznego pęknięcia i stanu granicznego po pęknięciu. W artykule poruszono także kwestię pracy szkła laminowanego w elementach konstrukcyjnych. W zależności od stopnia zespolenia tafli szklanych i międzywarstw polimerowych lub jonomerowych, można wyróżnić szkło laminowane całkowicie zespolone, lub niezespolone, a także pracujące w sytuacjach pośrednich. Biorąc pod uwagę charakter pracy szkła laminowanego, przy jego projektowaniu oblicza się tzw. grubość efektywną. W artykule omówiono metody wyznaczania grubości efektywnej zawarte w europejskich normach i wytycznych.
