Abstract
A transverse span for an airform membrane is disclosed that can include a material having a perimeter defined at least in part by a longitudinal edge having opposite ends that terminate at a base edge further defining the perimeter. The longitudinal edge can be configured to couple to a longitudinal edge of an adjacent transverse span of the airform membrane. The base edge can at least partially define a base perimeter of the airform membrane for coupling with a base support structure. The transverse span can also include a load compensated region with a length dimension and/or a width dimension reduced from an intended final dimension to compensate for stretch of the material when the airform membrane is inflated. In addition, the transverse span can include a flare region between the load compensated region and the base edge. The flare region can transition in the length dimension and/or the width dimension between the load compensated region and the base edge.
