    摘要： According to the method, at least one carbon fibre-reinforced polymer band is joined to the steel structure at the end regions thereof, capable of transferring tensile forces. Subsequently, at least one lifting element (7) disposed between the carbon fibre-reinforced polymer band (4) and the steel girder (3) to be reinforced in a region between these end anchorages (5), is extended substantially perpendicular to the carbon fibre-reinforced polymer band (4). So, a tensile force stress is generated between the end regions of the carbon fibre-reinforced polymer band (4). Then, a steel girder treated in such a manner includes at least one carbon fibre-reinforced polymer band, which is each joined to the steel structure (1) at the end regions thereof, capable of transferring tensile forces. In the region between these end regions, a lifting element (7) is disposed between the carbon fibre-reinforced polymer band (4) and the steel girder (3) to be reinforced, by means of which the carbon fibre-reinforced polymer band (4) is subjected to tensile stress by lifting away from the steel girder (3). The tensile force is transferred to the steel girder (3) via the anchoring elements (5).

    摘要： A Bailey beam for reinforcement is composed of Bailey panels, stiffening rods, bolts, anchor bolts, a prestressing tendon and anchorages. The components of the Bailey beam are all prefabricated in a factory, and are assembled and hoisted on site. The prestressing tendon is arranged in a lower chord of the Bailey beam, and is anchored to the stiffening rods at both ends. The Bailey beam slides towards both ends during prestress tensioning. In this case, the Bailey beam is lifted as a whole, and the prestressing force is applied to a lower edge of the Bailey beam, resulting in an inverted arch of structure, closing up of cracks and a decrease in downward deflection. After the completion of the prestress tensioning, sealing is performed by fixing fillers, a sealing steel plate and injecting solidifiable materials.

    摘要： A work vehicle (1) including a suspended platform includes a work cage (10) to carry an operator, an arm mechanism (60) having a distal end, the distal end movable to an intended position by at least one of a rotating mechanism (30), an extension mechanism (40), or a derricking mechanism (50) installed on a vehicle body (20). The suspended platform (100) includes a support post (70) located at the distal end of the arm mechanism (60), a suspension frame (80), from which the work cage (10) is suspended, mounted on an upper end of the support post (70) to allow the operator to perform an operation above the upper end of the support post (70), and a lift mechanism (90) that raises or lowers the work cage (10) suspended from the suspension frame (80) with a plurality of lanyards (91) to a work position.

    摘要： The disclosed technology is a system and a method for strengthening one or more joints of a structure having a plurality of structural members forming a vacuous area at each joint. The method includes computing limit load bearing capacity for the structure, at a joint, securing a filler module to the joint, at the vacuous area, the filler module having a plurality of surfaces so that when secured within the vacuous area, some of the surfaces are tangential to the members of the structure at its joint, and one or more of the surfaces are non-tangential to the members of the structure, and applying at least one layer of continuous fiber reinforced polymer wrap about the filler module and the members at the joint. The filler module of the disclosed technology is designed and configured to dissipate energy from a load applied to the structure, and at least doubling the load bearing capacity for the structure, at the joint.
