Today's understanding of architecture has revealed the need for structures that allow geometric form changes due to spatial and functional requirements. For this purpose, deployable structures have taken their place in architecture. These structures provide flexibility and multiple uses. While scissor mechanisms and bar mechanisms have been observed in architectural applications in deployable structures, over-constrained linkages have been used especially in recent studies of deployable structures. Over-constrained linkages make deployable structures more stable to loading. In this dissertation, the possibilities of systematically designing the single degree of freedom (DoF) networks using a kind of spatial overconstrained linkage called Altmann linkage as a basic module. The literature is investigated deeply that the conducted studies on network assemblies have been on different over-constrained linkages as a basic module, such as Sarrus, Bennett, and Bricard. There are few studies related to the Altmann linkage. None of these studies are in-depth studies to design a network based on the Altmann linkage. Also, an architectural application of the Altmann linkage has not been studied yet. This dissertation represents three main subjects: understanding the geometric properties of an Altmann linkage, designing one degree of freedom networks of Altmann linkage, and designing and analyzing an Altmann light shelf. Firstly, the geometry of the unit linkage is parameterized and its position kinematics is solved. Then, ten different single DoF Altmann networks are designed. By choosing one of the ten different networks designed, the network with folded and vault configurations is developed through assembly mode change. Afterward, light shelves are designed in Solidworks. Then, square and rectangular designs are compared in terms of their angles with the building and the west. Finally, daylight performance analyzes are made in the Relux software.
