A composite structural beam includes a metal frame including frame members extending along at least three axes. The metal frame defines an interior cavity. An internal wood member is located within the interior cavity and is configured to provide structural support to the metal frame. At least one external wood member is connected to the metal frame such that at least a portion of the metal frame is captured between the at least one external wood member and the internal wood member.

Disclosed herein is a method of manufacturing a modular building structure. A plurality of structural truss modules are provided. Each one of the structural truss modules includes a spaced pair of elongated wood chords and a web connecting the elongated wood chords. The web including a plurality of metal support rods each having a pair of opposed threaded sections. The first of the pair of opposed threaded sections engaged to a first one of the elongated wood chords at an angle thereto. The second of the pair of opposed threaded sections engaged to the other one of the elongated wood chords at an angle thereto. The structural truss modules are cut to a predetermined length. A first member is connected between the spaced pairs of elongated wood chords. First ends of the plurality of structural truss modules are configured to connect to a ledger member.

A formwork support for supporting concrete formworks in the construction sector, comprising an upper flange and a lower flange, which are connected to one another via a hollow profile web such that they are at an invariant distance in relation to one another, wherein the hollow profile web is stiffened inside by framework struts.

The present invention provides a building comprising a foundation; a wall supported by the foundation; and trusses supported by the wall. A plurality of hold down assemblies connects at least some of the trusses directly to the foundation. Each hold down assembly comprises an anchor; a tie-rod connected to the anchor; a bearing plate operably associated with an end portion of an associated truss for transferring load to the tie-rod; and a fastener securing the tie-rod to the bearing plate, thereby tying the associated truss directly to the foundation.
