In the endeavor to find a structure to support such a high pitched roof I came upon a system commonly used in Western European churches. The scissor truss in this example has a nominal depth of 6 ft at its highest and tapers to 4ft as the roof slopes to accomodate the angle of the sun. These steel trusses are set 4 ft O.C. and rest upon precast concrete walls. These are not meant to be working drawings but rather diagramatic structural images I will incorporate into the final poster.
