A method of construction of composite wall module system in which a first wall module and a second wall module are coupled to the first wall module by a vertical joint. The vertical joint is comprised of plurality of anchors and reinforcement bars as well as steel side plates allowing composite wall steel faceplates to be discontinuous across the vertical joint. The faceplates of the first and second modules are not made continuous across the vertical joint through continuous welding. The vertical wall joint further includes fill disposed between faceplates and side plates adjacent to anchors and reinforcement bars.

A building assembly includes a floor frame, a roof, and walls extending between the floor frame and the roof and interconnected to define an interior and exterior of the building assembly. Each wall includes panels each defining an axis and having first and second ends, inner and outer sides, top and bottom surfaces, an upper notch formed through the top surface, and a lower notch formed through the bottom surface. Each notch is spaced inwardly along the axis from at least one end. The panels include first and second panels. The lower notch of the first panel mates with the upper notch of the second panel to form an interlocking joint to interconnect the first and second panels and form adjacent interconnected walls of the building assembly.

A construction module for constructing a structure, including an elongate member having a substantially L-shaped cross-section provided with connecting portions arranged to detachably attach with connecting portions on second and further construction modules, to form structure. A temporary structure can be formed from two or more of the construction modules. The structure may be temporary, semi-permanent or permanent.

A module for realizing modular building structures comprises a bearing block having pairs of flat faces with complementary shaped joints for coupling with further similar modules arranged in side by side position, means for anchoring the bearing block to bearing blocks of side-by-side modules for realizing the building structure. The anchoring means comprise one pair of passages mutually perpendicular and staggered along a first transverse direction, the passages extending in the block from respective flat faces. The anchoring means also comprise reinforcing bars adapted to be inserted in a pair of consecutive passages belonging to two mutually side-by-side modules to define a reinforcement meshed armor. Each bar has ends associated with male and female connecting elements for coupling with facing ends of contiguous bars belonging to a side-by-side module.

Precast construction elements are described suitable for use in high seismic area. The precast construction elements can be precast, pre-topped double tees. The precast construction elements incorporate a passive energy dissipation device in a flange. The energy dissipation device provides a ductile connection having a deformation capacity of larger than 0.6. Adjacent elements are connected to one another at joints that include the passive energy dissipation device. Passive energy dissipation devices can be passive hysteretic dampeners, such as U-shaped flexural plates. Passive energy dissipation devices can be bar dissipaters (e.g., grooved dissipaters). Also described are passive hysteretic dampers that include U-shaped flexural plates held in conjunction with a reinforcement element that defines a circle around which the flexural plate can bend.

A stud such as a light-weight metal stud can include a first elongated channel member and a second elongated channel member coupled to the first elongated channel member by a wire matrix, where ends of the wire matrix are located at ends of the first and second channel members. A pitch of the wire matrix can vary over the length of the stud. Two or more such studs can have different lengths where a difference in the lengths is not a multiple of the pitch.
