The present invention relates to an industrialized construction process of at least part of a structure (1) to be constructed, by applying it, for example, to bridge decks, in which the filling material (8) is poured in situ on empty segments (3) prefabricated ex situ.

The construction process according to the present invention comprises the prefabrication of empty segments (3) including the assembling of steel reinforcement elements (9) and assembling fixing elements (4) whereby these comprise rigid elements (22) and at least part of the moulds (13), which occur at a location (5) ex situ, for example at the factory, construction site or at a place close to the works front line; transport and placement of the empty segments (3) in the final position in the structure (1); the operation of pouring the filling material (8); consolidation or curing of the filling material; prestressing the structure (1), if applicable; removal of the moulds (13) and fixing elements (4); followed by the start of the next cycle, if applicable.

The present invention also relates to a construction system adapted for carrying out a construction process of a structure (1) to be constructed.

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.

Disclosed is a self-centering viscous damper with pre-pressed ring springs. The self-centering viscous damper with pre-pressed ring springs comprises a first inner cylinder, a second inner cylinder, a third inner cylinder, an outer cylinder, a first end cover, a second end cover, a piston, a piston rod, a ring spring, a first connector, a second connector, a first linking nut, a second linking nut, a first outer cover, a second outer cover, a first end and a second end. Due to the interaction between the inner and outer cylinders, the ring springs are further pressed whether a damper is tensioned or pressed. The ring springs have been applied with pre-pressure which overcomes a frictional force and a restoring force when the ring springs are in an initial equilibrium position.

A bridge assembly includes a plurality of platform members which may be secured to support beams via individual platform chassis which are configured to allow tool-less attachment bolt heads thereto. A plurality of specially configured clamps are attached to the free ends of the bolts and the clamps are used to secure the platform members to the platform chassis. The platform chassis are each secured to the outer support beams via L-brackets that are mounted between the chassis and support beams. The support beams include flanged channels wherein the heads of a plurality of bolts may be attached without the need for tools. The platform members may be laid in either a parallel or perpendicular orientation with respect to the outer support beams with two different clamp styles being used depending on the orientation selected.

An earthquake resistant and reinforcing device for buildings and bridges is provided. In this device, two support mandrels are disposed on two ends of a main tube, and one ends of the two support mandrels are inserted in to the main tube. Baffle plates are disposed near the ends of the two support mandrels in the main tube, and sheath covers are disposed at the ends of the two support mandrels outside the main tube. A first elastic part is disposed in the main tube and between the baffle plates of the two support mandrels. A second and a third elastic parts are respectively disposed between the baffle plates of the support mandrels and the sheath covers. This device can be installed between beams and columns of buildings and bridges for effectively absorbing the energy waves acting thereon and thus increase the safety of the buildings and bridges.

A tension member with at least one loop made from fiber-reinforced plastic, which tension member has a plurality of fibers that run substantially parallel to each other, so that the loop is formed by the plurality of fibers, wherein a first group of fibers is turned over along the loop in a first turning direction, while a second group of fibers is turned over along the loop in a second turning direction, which is opposed to the first turning direction. Some of the turned-over fibers of both groups end in a different distance from the vertex of the loop than others of the turned-over fibers, so that a cross-section of the tension member that results from the respective number of fibers that run approximately parallel to each other outside the turning-over area of the fibers approximately continuously decreases until it reaches the cross-section size of the tension member.
