The research aim is to develop a prototype for a grid shell structure made of transparent polymer. Research objective was set to facilities the achievement of its aim, by firstly building a background about shells and form find a catenary grid. As, it will be the simplified example for shells in order to experiment new material and spatial property. Moreover, identifying the local materials to be used UR - http://172.23.153.220/th.pdf ER -
