Disclosed is a seismic reinforcement structure and a seismic retrofitting method, including: a first bracket including a horizontal part extending in contact with the bottom surface of the building, and a vertical part formed in connection with the horizontal part and extending in contact with the wall surface of the building; a second bracket including a horizontal part extending in contact with the ceiling of the building, and a vertical part formed in connection with the horizontal part and extending in contact with the wall surface of the building; and a connecting support rod having a vertically long shape and vertically connecting the horizontal part of the first bracket and the second bracket, wherein the relative position to the bottom of the whole building is fixed, thereby preventing the building from collapsing.

A construction system for a wall or floor or roof uses a set of studs having panel engagement features protruding from opposed edges of the stud. Panel elements having apertures receive these features so that they protrude through the panel element apertures. Retainers engage the panel engagement features and press against an outside surface of a panel element and towards the studs with a compression force to form a compression joint. There may be rails to form a mesh with the studs, and the panel elements may not be wide enough to abut each other, narrow panel elements providing sufficient structural strength in combination with the compression joints and the studs.

A composite assembly includes a series of elongated layers joined lengthwise thereof. At least two of the elongated layers each have an upper elongated portion and a lower elongated portion secured together in an end-to-end relationship at a joint therebetween by a connector arrangement. The upper elongated portion is constructed of a wood material, and the lower elongated portion is constructed of a non-wood material. The lower elongated portion may have a reinforcing rod therein.

A building and construction method include improved workability not causing variation in quality of buildings, by easily joining materials without special processing by forming mortises. A wooden building constructed by fitting horizontal and vertical members includes lower frames, first upper frames, second upper frames, and side joists as horizontal members; and pillars as vertical members, wherein the lower, first upper and second upper frames, and side joists include mortises at part of the lower, first upper and second upper frames, and side joists in longitudinal direction, the first upper frames include an entire length recessed groove in longitudinal direction, the second upper frames include an entire length protrusion in longitudinal direction, the mortises at the lower frames and the first upper frames are through holes, and the pillars include protrusions at both ends, fitting into the mortises at the lower, first upper and second upper frames, and side joists.

A building framework is disclosed herein comprising a first structural member, a second structural member, and a third structural member disposed between the first and second structural members, a first web member connecting the first and third structural members in a spaced apart relationship, and a second web member connecting the second and third structural members in a spaced apart relationship. The first web member is positioned relative to the second web member such that the shortest distance between the first web member and second web member is greater than or equal to 5 times the thickness of the third structural member. Additional products, systems, and methods also are disclosed.

A construction system for structural frameworks of buildings is described, comprising a first and a second structural elements mutually connected by connecting elements, the first and second structural elements being vertically assembled to make a pillar of the framework, a third and a fourth structural elements mutually connected by connecting elements to make a beam of the framework, the third and fourth structural elements being assembled transversally to the first and second structural elements, the third and/or fourth structural elements being associated as joint to the first and/or to the second structural element, the third and fourth structural elements being further connected to the first and the second structural elements by connecting elements, to make the framework, the first, second, third and fourth structural elements being composed of a panel having height and width greater than the thickness.

A construction technique, for example for residential, light commercial and multifamily building construction, involving pre-fabricated elements. The elements include prefabricated structural components and prefabricated surface components. A technique of incremental building includes assembling a building structure using these pre-fabricated elements.

The present subject matter relates to a device for coupling two vertical components, comprising a girder made of wood, in particular glued laminated timber, and a connector for each end face of the girder for connecting the end faces to one of the vertical components each. Each connector has two fittings, one of which is mounted via one side on the respective end face of the girder and the other of which can be mounted via one side on the associated vertical component and which fittings can be brought via their other sides into abutment against one another. Further, each connector has two tensioning jaws, which grasp the fittings at diametrical ends and can be tensioned against one another by means of at least one tensioning element running approximately parallel to said other sides. The girder has a bottom chord made of steel, which bottom chord is anchored at each end face of the girder to the fitting mounted thereon. At least one tensioning member is provided for tensioning the bottom chord.

An engineered wood structural system including multiple vertical structural elements (10) and multiple horizontal structural elements (20, 120) wherein multiple horizontal structural elements (20, 120) of the same floor level are laterally adjacent slabs connected to each other through a perimetral region of the upper horizontal board of one slab attached to a perimetral region of the upper horizontal board of other laterally adjacent slab directly, through complementary staggered steps or through a joint connector, to transfer horizontal loads.

The fixing metal fitting including: a joint base in groove shape mainly composing a joint metal; a cover spacer in groove shape capable of supporting the pillar's axial load by covering the joint base, wherein joint base including: a plane section in rectangular shape coinciding with an end surface of the pillar; a pair of groove walls bent vertically in L shape; and a joining plate standing from the plane section and supported by welded part J contacting at least the pair of groove walls or groove bottom, wherein the cover spacer including: a plane section in rectangular shape for supporting pillar by abutting to the pillar's end surface; a pair of groove walls composed of side edges of plane section respectively bent vertically in L shape; and a slit drilled such that the joining plate will be fitted into slit when the cover spacer is covering the joint base.
