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.

Various embodiments of mounting structures for solar photovoltaic (PV) modules and methods for constructing such mounting structures are described. A mounting structure is usable to secure PV modules in portrait orientation or landscape orientation. PV modules are secured to PV module support rails, which may be secured to purlins of a mounting structure using clamps. In some embodiments, self-adhesive grounding patches are used to establish electrical grounding paths in various embodiments of mounting structure.

The present disclosure relates to a common tower configured to be erected adjacent a building structure into construction. The tower comprises spaced apart columns, made of vertically aligned column hollow sections, spacedly and substantially vertically positioned adjacent the building structure, and vertically spaced apart flooring structures releasably and slidably supported by the spaced apart columns using a plurality of sliders. Each flooring structure is being capable of vertical displacement when supported by the spaced apart columns. The tower further comprises an anchoring system adapted to securely engage with the building structure to maintain the spaced apart columns substantially upright, as well as protection structures adapted to surround the flooring structures. A safe and easy erection of the tower using a common tower assembly is described.

A connecting hardware, comprising: first anchoring holes, aligned on a first base line, configured for connecting to a first hardware; and arcuate slots, arranged along a plurality of parts of circumferences, respectively, configured for connecting to a second hardware, wherein the plurality of the parts of circumferences are corresponding to a common center of circle, wherein the first base line and the plurality of the parts of circumferences are on a plane.

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.
