The CASTonCAST system consists in designing and producing architectural freeform shapes from precast stackable components. This allows fabricating and constructing curved shapes in concrete in an efficient and sustainable manner. Currently, the geometric modeling process of the system does not ensure that the shapes are load-bearing. This article introduces a method for the design of shell structures from stackable components based on the CASTonCAST system. In this research, the structural analysis is conducted using load path network method since this method helps integrating design, realization, and structural aspects.
