Trilithic Shell, Twin Shell, Multiple Shell, Curvilinear Shell as well as Free-formed Structures described herein each employ an inflatable membrane having a peripheral edge secured to an outer foundation base. An ultra-light membrane (air-form) having a network of internal cross connecting restraints is additionally secured to the inner foundation base to permit a novel and unique curvilinear surface. Pressurization then creates the backdrop upon which various urethane layers are applied which when laced with rigidifying tubes become the defining backdrop beneath which numerous cross connecting braces which when snapped into position effectively lock an inner framework to an outer framework thereby producing a self supporting truss like structure both compatible with either current dome construction and / or conventional construction practices. Shotcrete being then sprayed from the interior over said urethane coated backdrop forms highs at framework intersections and natural lows in between followed by the insertion of inflated cell tubes which span the created network of horizontal and vertical cavities are next over sprayed with urethane foam necessary to form the next natural backdrop over which two or more shotcrete / steel reinforced separate yet cross connected planes may be achieved. Such multiple yet independent rigid layers now having thousands of inner-connecting cross braces through which interior voids become natural chase-ways effectively displace 50% or more of what might otherwise be solid concrete as would be the case with all prior art thin shell structures and / or conventional stem wall construction practices. Such Free Formed curve-linear structures effectively reduce material and labor costs by as much as 50%, eliminate snap-through or oil-can buckling tendencies, enhance overall structural capacity, eliminate all height to diameter restraints, permit larger structures, facilitate floor suspension and attachment, and allow mechanical, electrical and HVAC distribution through interior chase-ways which cannot be achieved with prior art concrete thin shell single thickness structures and / or conventional stem wall, construction practices to date.
