A beam system and method of erecting a supporting arch enables large roofed structures to be erected quickly and economically. The method includes aligning a plurality of structural elements longitudinally; connecting upper corners of the structural elements to upper corners of adjacent structural elements, wherein adjacent lower corners of the structural elements remain unconnected; elevating first and second structural elements in a middle of the supporting arch; connecting lower corners of the first and second structural elements together; elevating third and fourth structural elements adjacent the first and second structural elements, respectively; and connecting lower corners of the third and fourth structural elements to lower corners of the first and second structural elements, respectively.

A load bearing structure including a first fixed net layer, a second fixed net layer and a non-linear structure in between. The first fixed net layer may include a first layer of flexible, drapable fabric and a fixing material that fixes the shape of the first layer of flexible, drapable fabric. The second fixed net layer may include a second layer of flexible, drapable fabric and a fixing material that fixes the shape of the second layer of flexible, drapable fabric. The non-linear reinforcing structure may be in communication with the first and second fixed net layers and may be configured to share with the first and second fixed net layers a load applied to the load bearing structure.

The invention is a system and method for building a polar zonohedron structure from precast cement panels. The building system may include a plurality of panels configured to register with each other. Each panel includes a precast cement base with side walls enclosing a cavity within the precast cement base. The panels include at least one ridge protruding from at least one surface of a side wall of the panel and at least one aperture on at least one surface of a side wall of the panel. Each ridge is preferable configured to interlock with each aperture; in his way, the panels interlock with each other to form the polar zonohedron structure.

A laminated structural arch system for supporting a horizontal planar structure, comprising at least one laminated arch. Each laminated arch is comprised of a plurality of arch plates rigidly fastened together in parallel, and forming a laminated configuration. Each arch plate is separated from the arch plate adjacent to it by a separation gap. The laminated structural arch system may contain two or more laminated arches positioned in parallel and secured to an anchoring structure, allowing one or more panels which comprise the horizontal planar structure to be positioned across and supported by the laminated arches. The laminated structural arch system may be provided as a kit of disassembled arch plates, allowing the system to be easily transported, handled, and assembled.

The invention relates to a dome- or sphere-shaped multipurpose building, which is a prefabricated quickly erected structure and can be used for erecting the buildings of various functional purpose, of different number of storeys, both warm and cold, including residential buildings, cottages, industrial, administrative, sport, agricultural, warehouse, temporary portable buildings, arch structures, atrium roof, atrium room, located above the top floor of a building. Technical result of the claimed invention is to reduce the material consumption, installation time, increase the strength and stability of the building, including under conditions of asymmetrical and dynamic loads, and to increase energy efficiency and translucence of the building. The multipurpose dome-shaped building comprises a bearing frame having a base and an apex in the form of polygons of different perimeters, a roof in the apex of the bearing frame coated with a facing material, wherein the bearing frame is made in the form of at least three pyramidal volumetric trusses arranged symmetrically with respect to the base center and rigidly connected to each other in the upper part by at least one horizontal beam, and wherein the volumetric trusses are arranged in such a way that the horizontal distance between closest posts of neighboring volumetric trusses remains the same over the entire height from the base and up to the top of the neighboring trusses.
