The present invention relates to a concrete-filled steel tubular column-steel plate concrete ring beam joint, comprising: a concrete-filled steel tubular column, a steel plate concrete ring beam and reinforced concrete frame beams. The steel plate concrete ring beam comprises: a steel plate and a reinforcing cage, wherein concrete grouting holes are arranged in the middle of the steel plate; both the steel plate and the reinforcing cage are of a ring shape, and the ring-shaped steel plate and the reinforcing cage are coaxially arranged; the steel plate concrete ring beam is sheathed and fixed on the outer side wall of the concrete-filled steel tubular column; and an end of the reinforced concrete frame beam extends into the steel plate concrete ring beam, and stressed reinforcements of the reinforced concrete frame beam are connected to the steel plates. The steel plate concrete ring beam is of a centrosymmetric ring-shaped or eccentric ring-shaped construction. The stressed reinforcement of the reinforced concrete frame beam is anchored by the ring beam joint through the steel plates, so that the seismic performance of the connection joint is ensured, the section width of the steel plate concrete ring beam can be significantly reduced, and the spatial applicability of the joint is improved. The present invention also relates to a construction method of a concrete-filled steel tubular column-steel plate concrete ring beam joint, belonging to the field of building structures.

Described is a system for transmitting a flexural wave acting on one structure to another structure. In one example, a system includes a first structure having a first property and a first end and a second structure having a second property and a second end connected to the first end of the first structure. The first property is different from the second property and may be related to the material and/or geometric properties of the first and second structures. A mechanical resonator is connected to the first structure at a distance from the first end of about a quarter-wavelength of the frequency of a flexural wave acting on the first structure. The mechanical resonator matches a first mechanical impedance of the first structure to a second mechanical impedance of the second structure to allow high transmission of the flexural wave acting on the first structure to the second structure.

A column insulated beam construction system for living spaces based on a single element constructive, conceived for the construction of beams and columns, which by means of rigid joints they form a structural framework without the need of internal reinforcements, with a resistance to deformation as well as with a high thermal insulation capacity. which by uniting with each other assemble a volume that ultimately constitutes a thermally isolated.

A universal hub adapter for a portable display frame assembly, the hub adapter being configured to mount to an outer surface of a display hub of the frame assembly. The universal hub adapter is configured to adapt the display hub of the frame assembly between the mounting of a first graphics system including a plurality of stretched fabric panels and a second graphics system including a channeled sub-frame for mounting a larger fabric panel. The universal hub adapter can include a faceplate having a substantially planar outer surface and a concave inner surface configured to mate with the convex outer surface of the display hub and a threaded post having a threaded portion, a securement plate, a button shaft, and a button head, the threaded portion configured to pass through an aperture of the faceplate and couple to the display hub, such that the securement plate abuts up against the faceplate thereby securing the faceplate to the display hub, the button shaft and button head configured to operably couple to one of a stretched fabric panel or a sub-frame assembly.

There is provided a horizontally and vertically extendable building structure module that includes a panel, a structural frame and one or more beams. The panel may be designed to form or set into a floor, ceiling, wall, window, door or any other components that may cover surface of the building. The structural frame may be designed to provide the structural shape and strength and hold the panels. The beams may be designed to connect and align the structural frame. The horizontally and vertically extendable building structure module is configured to build a building structure without additional structural support. Because of the minimized number of components for the building structure, time and cost for building construction may be reduced.
