Abstract: The present invention relates to a prefabricated infilled panel-frame structure capable of accommodating seismic-loading and seismic energy dissipation, and a construction method thereof, including a frame body, a prefabricated infilled panel group, a panel connector, and a disc spring assembly. During an earthquake, the present invention slides to dissipate energy only after the maximum starting sliding force is exceeded, thus providing the structure with a relatively high lateral stiffness prior to sliding. After an earthquake, the disc spring assembly of the present invention may provide a certain restoring force due to being compressed so as to reduce the residual displacement. Further, the present invention achieves the bidirectional deformation cooperation of the prefabricated infilled panel under earthquakes, so that the infilled panel may still achieve the function of seismic energy dissipation under the coupling action of in-plane and out-of-plane loads.

Abstract: A structural assembly and a structural bracing system including the structural assembly are presented. The structural assembly includes Belleville disks and shape memory alloy (SMA) rods with nonlinear elastic behavior (e.g., Nitinol rods) to resist lateral force. Stacked Belleville disks are placed between plates resulting in nonlinear elastic behavior in compression. Shape memory alloy rods are placed at the corners of the plates and held by nuts at the exterior faces of the plates. The rods are loose when a compression load is applied to the plates and will work in tension when a tensile load is applied to the plates. A shaft (e.g., steel tube) is placed at the center of the Belleville disks to stabilize the assembly. Addition of the assembly with nonlinear elastic behavior in both tension and compression loadings to a structural bracing system improves the structural behavior of the bracing system.

Abstract: 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.
