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 post, beam and arched member modular building is shown. The modular building may be formed into any number of different configurations and different structures. The system relies upon a box shape formed from four vertical members, with an arched member extending between each of the adjacent vertical members. The rear vertical members being higher than the front vertical members, with angled members, or rafters extending from the rear vertical members (or a cross-member at the same height thereof) to the front vertical members (or the corresponding arch). In the configuration shown, the angled members or rafters are co-planar. The structure has substantial symmetry and aesthetic design.

The present disclosure discloses a building information modeling (BIM)-based modular housing built with thin-wall channel steel comprising foundations, columns, beams, walls, a roof plate, doors, and windows. The columns and transverse beams adopt inward-flanging C-section steel or combined square steel arranged by oppositely buckling symmetric inward-flanging C-section steel. The columns and foundations, the columns and transverse beams, adjacent transverse beams, the columns or transverse beams and slant beams, the transverse beams or slant beams and roof plate, and joints of adjacent supports are connected to each other together by base connectors, butting connectors, or crossed connectors. According to the technical solution of the present disclosure, the inward-flanging C-section steel can be quickly and securely butted, or combined square steel can be quickly and securely butted. The joint is provided with webs, and can be used as a standard connector due to high strength. Relief holes provided at the inner side of the joint are buckled with inward-flanges of the inward-flanging C-section steel to each other and pressed together, thereby realizing an internal-external nesting effect. A positioning groove arranged outside the joint and the inward-flanging C-section steel can be nested together in a concavo-convex manner, and then pressed and fastened by a fastening steel strip, thereby realizing effects of fastening and slippage prevention.

A structural support beam for use in buildings, bridges, mechanical frames and the like to resist bending due to gravitational and external forces comprising a top substantially flat flange disposed in fixed spaced relationship relative to a bottom substantially concave flange by an interconnecting web and a lower stabilizing brace disposed to engage the opposite end portions of the bottom substantially concave flange and the opposite end portions of the interconnecting web to reinforce the interconnection therebetween.

A new approach for modular construction is a type of connection that can be used to form structures of different depths and/or variable-depth structures. Advantages of this approach include prefabrication, mass-production, and rapid erection which can lead to reduced constructions costs and time. Applications include all forms of truss type structural systems, but with particular emphasis on bridge and building structural systems.
