Abstract

In this paper, we describe the example of the tunnel-shaped form building that was designed by structural morphogenesis and constructed. The genetic algorithms(GA) is applied to the structural morphogenesis of the framed construction of this tunnel type. In the numerical result, we show various solution forms of the arch shape by giving some design constraints. An effective structural form for the structure, the design, and the function is searched from the combination of the obtained arch shape. This simple structural morphogenesis procedure will become the hint of the design tool that decides the building shape.
