Torroja’s cantilevering roof uses prestressed concrete to achieve remarkable span and thinness. This model displays the compressive forces using numerous transparent cross sectional pieces held together only by a string through holes in each piece, simulating the steel rebar tightened on site. As demonstrated, the model is flexible upward but rigid downward, as the shape of the cable is particular to the stresses of the arched geometry.
