A system of construction that performs advanced prefabrication of columns-beams type structure of buildings, prefabrication which results industrialization of this type of construction. The main development that allows this achievement in the same technical conditions, even better conditions than in the conventional system, is the massive use of braces as well vertically as horizontally. Such a building system is of special interest in areas where seismic risk is high because the building is very lightweight, constituted of a set of structurally self-sufficient units, heavily triangulated and therefore hardly deformable, all these at an affordable cost.

In carrying out a loft conversion some way has to be found of reinforcing the triangular timber roof trusses so that the internal bracing can be removed, to make the space. In the invention this is done by fixing C-sections to the outline of the triangular trusses, preferably sandwiching the timber frame. For the C-sections to overlap at the corners, part of one flange, e.g., the upper flange of the horizontal beam, is removed, and then the beams are bolted onto the frame. The process can be carried out with minimal disruption to the roof as no transverse (longitudinal) reinforcement is needed. A dormer process can also be included, making use of a versatile reinforcement plate.

A building framing system includes a floor portion or floor framing system, a wall portion or wall framing system, and a roof portion or roof framing system. Each framing system comprises a plurality of components. Each component defines a connection geometry for connecting one component to another. The connection geometries are such that mechanical or other similar fasteners are not required to hold the various components together; rather, the connection geometries connect the components and hold them in place with respect to one another. Further, the framing systems utilize pre-cut components such that the components of each framing system arrive onsite cut to a needed length and width and with the appropriate connection geometry.

A multi-story boxed wall frame system for reinforcement of multi-story structures includes first and second boxed wall frames disposed one on top of the other and connected together. Each boxed wall frame includes first and second columns, and first and second panel zones attached to the respective first and second columns at their top ends. Each of the panel zones includes yielding members and reinforcing structure at least partially bounding the yielding members. The reinforcing structure is configured to concentrate stresses to within the yielding member. A beam extends between the first and second panel zones in each of the boxed wall frames. The boxed wall frame is configured to resolve external forces into shear force in the yielding member such that the yielding members will yield prior to yielding of the beam and the columns.

A system and method of forming a wooden shear wall including a framed wall section having multiple framing members including a first and second end posts, a center post framing member, a mudsill bottom plate coupled to a bottom end of the framing members and a top plate coupled to a top end of the framing members. Two plywood panels are fastened to a first side of the framed wall section with a ductile metal gauge strap, ductile metal gauge strap securing adjacent edges of the plywood panels to the center post and multiple metal gauge straps, disposed along the edges of the plywood panels secure the edges of the plywood panels to the framed wall section.

A structural webbing to be custom cut and fit to individual job sites, allowing for the reduction or elimination of traditional beams used in structural building. Webbing uses angular forces to bear loads, resulting in reduction of thick beams. Elimination of beams allows for significant reduction in resource consumption and increase in thermal efficiency of structure. Webbing allows elimination of thermal shorts and increased space for insulating materials. Webbing consists of alternating nodes and members, wherein members are disposed at positive and negative angles to the nodes, creating a zig-zag pattern. May include upper or lower cords. Can be used in straight line for walls, window headers, doors, etc., or in curves or other more elaborate shapes for curved windows, etc. Suitable for load bearing walls, upper and lower floors. Nodes can be coupled with standard structural members such as king studs, head pieces, and top and bottom plates.

A prefabricated shearwall includes a central panel having reinforcing stiffeners within side edges of the panel. The central panel is provided with one or more corrugations to withstand both vertical (gravitational) and lateral loads. The stiffeners in the side edges provide improved resistance to lateral loads and controllable yielding to dissipate shear stresses within the shearwall.

A reinforced building wall includes a first stud wall disposed above a foundation; the first stud wall including a bottom plate, a top plate and first and second vertical studs extending between the bottom plate and the top plate; a first threaded rod having a first end portion embedded in the foundation and a second end portion extending through the bottom plate; a compression rod having a first end portion operably attached to the second end portion of the first threaded rod and a second end portion operably bearing onto a bottom surface of the top plate, the compression rod is configured to handle compression forces from the top plate without buckling; an anchor embedded in the foundation, the anchor is operably attached to the first end portion of the first threaded rod.

An adjustable lateral brace configured for bracing adjacent roof trusses, wall studs, or similar structural elements during construction of residential and light commercial structures. The brace comprises a horizontal member and a diagonal member connected by a living hinge. The brace is shipped to a construction site in a compact configuration in which the horizontal member and vertical member are substantially parallel. The living hinge is activated to dispose the horizontal member and diagonal member at an acute angle adjusted to the spacing of the members to be braced.
