Abstract
This paper is the structural design proposal for a complex building with undulating surfaces. The complex is one building that consists of four lines of hill-like roofs, called "waves", which are intertwined with each other. Moreover, this site has soft ground that includes many artifacts to be preserved as a cultural heritage. The main issues in the structural design were as follows: 1. Design of shapes considering both architectural aesthetics and structural rationality; 2. Implementation of systems which properly transmit seismic forces among the waves; and 3. Prevention of damages to the artifacts beneath the site.The authors propose a structural system with a curved surface on distributed supports. It has a hybrid behavior between shell and flat slab. This hybrid system realized load dispersion by using thin slabs and slender columns, and achieved the construction of the building on the soft ground.
