There are hardly any other building materials that could work with the popularity of glass throwing among engineers and architects. Glass has witnessed a period of evolution in architecture; From the period of bulky walls to transparent outer shells that allow light to pass through. Materials that give us the chance to implement transparency and weightless structures without interruption that change the relationship between inside and outside, the relationship between man, space, light, and nature. Today we have many options for intelligent control and determining the right amount of light and heat entering our building. Glass is increasingly being used by engineers as a load-bearing element, significantly reducing the proportions of members of bulky structures. Glass innovations are expanding rapidly recently. We are now able to meet the stringent requirements of fire resistance and safety. These vast innovations quench the thirst for information among engineers and architects. (Schittich, 1999) In recent years, successful examples of the use of glass as a structural shell of building have been made in the metropolises of Tehran and Mashhad which due to the lack of complete localization technology of this type of shell, especially due to the seismic conditions of Iran, the monopoly of design knowledge in a small number of consulting companies involved in the construction of these projects, as well as the lack of translation or authorship of specialized resources, exposes the lack of information and research in the field of design and consequently lack of knowledge of the potential of glass. Meanwhile, the history of designing structural glass façades outside Iran dates to the second half of the twentieth century with a change in approach to glass and the development of technology and related structural systems. Due to the relatively long period of time mentioned above, scientific sources and related research have been developed naturally. (author) In seismic areas, specific calculation methods are required to comply with displacement and resistance requirements, but design criteria are rarely considered in existing standards for earthquake-resistant buildings. Even more attention is paid to frameless glass systems in which restraining members (in other words, frames, cable nets, etc.) are minimized due to metal point connections (e.g., bolts and mechanical connections, or clamps, etc.) is required. (Bedon, Amadio, & Noe, 2019) The aim of this dissertation is to take a closer look at the components of the structural glass façades (SGF) by focusing on the seismic performance of each of these components. In this regard, after reviewing the research and the requirements of the existing regulations in the field of seismic design of SGF, first the types of common structural systems and prominent examples have been examined so that in the first stage the most optimal structural system and glass connection system can be obtained from seismic design point of view. Then, the innovations made to improve the seismic design of the smaller components of this system, such as glass and fittings, are reviewed and finally a comprehensive solution for all the main parts of the SGF is formulated and used in the design of the multiplex cinema-bridge. Systems are selected with the approach that the seismic enhanced details are practical, accessible and without too much complexity. In other words, design requirements for seismic performance evaluation should be performed through relatively simple but challenging structural solutions
