The present invention is a clip for use with a strut that at least partially surrounds a hanger rod for the purpose of providing stiffness to the hanger rod. The clip includes a handle portion, a rod-clamping portion, and a fulcrum spaced away from the handle portion. The fulcrum is for being mounted to the strut. The rod-clamping portion is for forcing the hanger rod into tight engagement with an engagement surface of the strut in response to the handle being actuated to an operational position. The present invention also relates to a hanger rod stiffening system that uses a clip and a strut, whereby a handle of the clip is actuated to force a rod-clamping portion of the clip into tight engagement with an internal surface of the strut.

An earthquake-proof masonry infill wall is described which comprises a series of superimposed masonry strips (7). Each masonry strip (7) comprises a plurality of blocks, that is masonry elements (8), arranged adjacent and horizontally such to occupy a space between two columns (3) of the framed structure (2). A sliding element (10) interposed between two adjacent masonry strips (7) has opposing section bar elements (11) that allow a masonry strip to slide in a guided manner with respect to another masonry strip in case of a movement of the infill wall.

The invention relates to an energy dissipating device (10) which is capable of dissipating energy through its plastic axial deformation without undergoing buckling. It is characteristic for the invention, that the energy dissipating device (10) comprises at least three hysteretic elements (15), being interconnected in series in such a way, that at least one hysteretic element (15) will be subjected to compression while at least another hysteretic element (15) is subjected to tension when an external load is applied to the energy dissipating device (10).

A buckling restrained brace comprises a core member, core restrainer member sections and a jacket member. The core member has two opposite ends. The core restrainer member sections are configured to be arranged around the core member. The jacket member comprises fiber reinforced polymers configured to be wrapped around the core restrainer member sections and core member to couple the core restrainer member sections to the core member such that the core restrainer member sections and jacket member cooperate to provide greater resistance to buckling of the core member when the brace is subjected to compression. In some implementations, the brace has a weight less than about 50% of a weight of a conventional buckling restrained brace of similar length and having a steel core and mortar-filled tubular core restrainer member of comparable cross-sectional areas, respectively.

There is provided a structure vibration control device including a hydraulic damper (1) whose damping force characteristics vary in response to magnitude of an earthquake and whose characteristics are maintained for a long period of time regardless of an environmental temperature change. The hydraulic damper (1) includes a preload chamber (29) into which high-pressure gas is charged in series with a hydraulic chamber (27). The preload chamber (29) absorbs volume change of the hydraulic chamber (27) caused by the temperature change and a piston rod (6) and balances a bias force of a spring (40) within the oil chamber (27a) and of the preload chamber (29). Piston valves (37 1 and 37 2 ) have a great damping force characteristics to a weak earthquake and a low damping force characteristics to a strong earthquake. The piston valves (37 1 and 37 2 ) may include an orifice beside a check valve function, by which the great damping force characteristics lies within a range of 150 to 800 kN/(m/sec).
