An anti-seismic device (1) for load-bearing structures or machines for example automated warehouses, comprises at least one supporting foot (3) suitable for being fixed to a load-bearing structure of the automated warehouse. The supporting foot (3) is configured for resting and sliding on a support and sliding surface (5), so as to allow relative movement of the automated warehouse with respect to the support and sliding surface (5). At least one abutment element (10) is suitable for being solidly constrained with the support and sliding surface (5). At least a spring device (12) is suitable for being interposed between the abutment element (10) and the automated warehouse. The spring device (12) is configured to generate a return action (force and/or torque) of the automated warehouse as a result of the relative movement of the automated warehouse with respect to the support and sliding surface (5). The spring device (12) has a non-linear, preferably progressive elastic characteristic.

A prestress-free self-centering energy-dissipative tension-only brace, including a self-centering mechanism, an energy dissipation mechanism, a force-limiting energy-dissipative mechanism, a high strength steel cable, and a sleeve. The self-centering mechanism includes a sliding end plate, a spring, and a connection rod. One end of the spring is connected and fixed to the inner wall of the sleeve, and the other end of the spring is connected with the sliding end plate. One end of the connection rod is anchored at the center of the sliding end plate, and the other end of the connection rod passes through a fixed end of the spring. The energy dissipation mechanism includes rotating shafts, rotating wheels, friction plates, chains, and a cross-shaped connecting piece.

A vibration control wall structure, which is introducible into a wall part of a building, includes a wall frame, a vibration control wall body, and a vibration control damper for absorbing a vibration acting on a building. The vibration control wall body includes a plurality of face materials which are fixed to a frame material via a fastening member and are connected to each other in a width direction. A gap part is formed such that both side end portions of the vibration control wall body are separated from the wall frame so as to absorb displacement in an in-plane direction. The vibration acting on the building is damped by the vibration control damper having a long hole in a longitudinal width direction of the vibration control wall body. The vibration control wall body can relatively slide in the long hole in the longitudinal width direction.

A precast segment suitable for block-stacking concept is disclosed. The precast segment includes a first surface, an opposite second surface, plural through holes, and plural male-female connecting sets. The through holes extend from the first surface and toward the second surface to communicate between the first surface and the second surface. Each male-female connecting set includes a shear key and a joint hole, wherein the shear key protrudes from one of the first surface and the second surface to serve as a male connecting unit, and the joint hole is formed in the other of the first surface and the second surface to serve as a female connecting unit. Accordingly, the precast segments can be block-stacked by mortise-and-tenon joints to construct a bridge pier system. Compared to the conventional construction methodology, the present invention can enhance the efficiency of segment fabrication and avoid high prestress force.

The present disclosure is generally directed to a sway brace attachment for a bracing system comprising a body defining at least one slot for receiving a flange of a structural support of a building, a set screw bar coupled to the body, and set screws threadably received in threaded openings defined by the set screw bar

A vibration damping device for a structure 1 includes a circular tubular member 3 having a circular tubular inner peripheral surface 2; a columnar elongated member 6 which is disposed in the circular tubular member 3 relatively movably in a direction X with respect to the circular tubular member 3 and having a circular tubular outer peripheral surface 5; and a circular tubular elastic member 10 which has a circular tubular member outer peripheral surface 8 fixed to the inner peripheral surface 2 of the circular tubular member 3 and a circular tubular member inner peripheral surface 9 fixed to the circular tubular outer peripheral surface 5 of the elongated member 6, and which is disposed between the inner peripheral surface 2 of the circular tubular member 3 and the outer peripheral surface 5 of the elongated member 6.

A method for on-site assembly of a shelter for an above-ground structure to protect the structure from blast, wind, fire or other physical hazards. A pyramidal shelter with triangular or rectangular base is formed by joining side panels to each other. Each side panel includes a triangular frame covered, except at access hatch, observation port and door openings, with either steel plate or diamond steel mesh to which blast-resistant, fire-resistant or other kinds of coatings or panels are applied. A corner anchor assembly to support each corner of a shelter has a lower plate, an overlying split plate, and a pair of upstanding, anchor rods attached to the split plates for insertion into hollow, lower portions of side beams of adjacent side panels. The corner anchor assemblies facilitate expansion of an assembled shelter by addition of more modular components.

A structural frame for a building includes a plurality of columns, beams, and beam-to-column connections. A plurality of braces are positioned in frame bays formed by respective pairs of columns and beams, each brace comprising a multi-piece brace having a plurality of brace portions. A plurality of discontinuous elastic zone connections couple the plurality of beams to the plurality of columns via the plurality of beam-to-column connections and/or couple pieces of the multi-piece brace together. Each of the discontinuous elastic zone connections comprises connection mechanisms and a compression element positioned on each connection mechanism, with each compression element comprising a single component or a plurality of deformable components in a parallel stack, a series stack, or a combination of parallel stacks and series stacks. The compression element is configured to provide elasticity in the structural frame and dampen the effects of transient loads on the structural frame.

Invention; is related to isolators eliminating circular forces caused by earthquake forces acting on the building. It is placed between foundation of structures manufactured by steel construction, concrete, prefabricated structure or other methods and structure and which reduces/terminates impact of earthquakes on structures. Thus, damage to be given by earthquake to carrying elements of building is eliminated.

A construction system includes a set of constituent elements, at least one of which includes at least two superimposed folds each including at least two wooden structural boards. In this system, at least two constituent elements are fixed together by a non-adhesive fixing device and at least two adjacent folds are held against each other by non-adhesive holding device. The faces in contact with two structural boards are at least partially provided, at their contact interface, with a set of grooved patterns arranged so as to prevent the structural boards from sliding one relative to the other along at least one first immobilisation axis. A method for manufacturing such a construction system is also disclosed.
