With an emphasis on computer aided modeling systems, this course aims to highlight the significance of structural systems in architectural design. The structural considerations should be taken into account at the very early stages of the architectural design. Under the light of this fact, this course aims to constitute a basic understanding of structural behavior of built forms. To reinforce this intend mathematical modeling techniques will be introduced with simple and approximate geometrical calculation procedures. Beside basic principles of writing data of the system for the computer analysis, the interpretation of the outputs will be introduced
