Abstract: A buckling-restrained diagonal brace is provided. The buckling-restrained diagonal brace mainly contains a core element and a restraining element. The core element is an assembly of a specific number of steel members having a specific shape whose cross-sectional dimension is determined based on the load requirement. The core element has a larger cross-section at the ends than at its medial section. The core element is encased in the restraining element. The restraining element manly contains a single or multiple steel tubes filled with concrete, mortar, or reinforcing members. The restraining element is to protect the core element so that it wouldn't be buckled and destructed under load. By using a lapping or an improved plugging type of connection to a structure frame, the buckling-restrained diagonal brace is able to yield steadily when loaded in both tension and compression and the buckling-restrained diagonal brace would have a full hysteretic curve.

Abstract: A tilt support structure is disclosed. The structure comprises a force exerted unit and a restriction unit, characterized in that the cross section of the end portion of the force exerted unit is larger than that of the middle section and the force exerted unit is mounted into the restriction unit, the restriction unit includes a single or a plurality of sleeves and in combination with concrete, cement slurry or enhanced steel beam or steel plate to form an external frame to restrict the main force exerted unit so as to prevent damage as a result of compression and the structure is stable under compression or pulling.

Abstract: A multifunctional shock-resisting structure is disclosed and the shock-resisting structure comprises (a) an external frame being an open or closed socket body of different shapes; (b) an actuating rod, and the material for the external frame, the braking layer and the actuating rod being different in softness or hardness; and (c) a braking layer being positioned between the external frame and the actuating rod, wherein after the actuating rod is inserted into the external frame the braking layer is filled into the space between the actuating rod and the external frame such that eh inner edge of the external frame and the actuating rod is interconnected by the braking layer.

Abstract: An earthquake energy eliminator is constructed to include two bearing plates respectively disposed at top and bottom sides, the bearing plates each having a plurality of mounting holes, and a plurality of connecting plates connected between the bearing plates, the connecting plates each having respective top and bottom sides respectively fitted into the mounting holes of the bearing plates and at least one opening spaced between bearing plates.
