This paper describes a study of form finding process of arch-like truss using force density method (FDM) with a shape control technique. When we try to find a form of structure based on FDM, we can get all possible shapes with only knowing element connectivity and giving various force density values. However if we want to give certain restriction to a shape of structure such as height or element length, then we would have to repeat iterations by trial and error when we use original FDM to satisfy those restrictions. To resolve the problem, this study is carried out to find and suggest a technique that includes a shape constraint during the form finding process based on FDM.
