IS 875-1987 (Part -1 Dead Loads) Indian Standard Code of Practice for Design The curtain wall is designed for the following Loads.
brackets) which attaches the mullions to the building. The loads imposed on the curtain wall are transferred to the building structure through structural interface (i.e. The Curtain Wall is designed to resist and handle all the imposed loads on it as well as keep air and water from penetrating in the building. Male Mullion and Female Mullion combine forms the unitized systems.įigure: 1.3 Assumption of Stress Distributionįigure: 1.4 Fixing details of unitized curtain wall system Nevertheless, the unitized system is the most popular façade system according to on manufacturer and it has performed satisfactorily when installed correctly. In a unitized system, the manufacturer must rely on qualified installers to ensure that the air seals are properly installed between the split mullions.
Assembly must be carried out in a specific sequence to ensure a proper fit. Quality control issues can be significantly reduced in terms of site labor, especially with pre-glazed units, but assembly at the plant and transportation (due to bulk) increases its cost.Īnother disadvantage to pre-assembly is any site changes become difficult to accommodate. As such, it minimizes field labor and erection costs, and promises a shorter installation period than the stick system. This system comes pre-assembled it can be pre-glazed at the factory or shop, or glazed on-site. The first curtain walls were made with steel mullions, and the plate glass was attached to the mullions with asbestos or fiber glass modified glazing compound.Ĭurtain wall meaning a set of aluminum profile like Mullion, Transom, Glass panel.Ībove three we used the unit panel system which is also called as unitized system. Mullion is a vertical support or we may call it as a column, while the transom is a horizontal support likely to a beam. For the architectural point of view the use of glass gave aesthetic view to the building itself.Ī structure supported by aluminum frame work which is made up of Mullion and Transom is called as a curtain wall. The use of glass in the exterior facades provided more of light and good ambience to the occupant of the building which gave rise to the increasing use of glass. The requirements of designing load-bearing structures are normally gotten from either the glass supplier or the producer of glass pane elements, who both are thereby responsible for the strength and functionality of the fastening.įaçade is a French origin word meaning the front face. This material property of brittleness has to be taken into account when designing large glass facades. Glass differs from other building materials in aspect of being an extremely brittle material and breaking without a forewarning. The use of glass in facades causes many problems due to the material properties of glass. The aim of this master’s thesis is to gather together information on research, design and codes about the structural design in steel-glass facades. By using steel as a load bearing structure, it is possible to keep the transparency restricting structures slim. This has rapidly increased the use of glass in facades. Today lightness and transparency are properties that both architects and clients try to obtain.
