摘要： A large-span and special-shaped arch bridge, comprising a main girder (2), a center abutment (11) served as a central bearing point and two auxiliary abutments (12,13) served as bearing points at two ends, wherein further comprising an arch-axis combination (3) and two arch-axis bending beams (4,5) presented as arcs projected upwards, the arch-axis combination being built on the center abutment (11) with two ends connected to the inner ends of the two arch-axis bending beams (4,5), the outer ends of the two arch-axis bending beams (4,5) being built on the two auxiliary abutments (12,13), the two arch-axis bending beams (4,5) being connected to the main girder (2) via a plurality of inhaul cables. A method for constructing said arch bridge is also disclosed. Through the dual-arch axis of two arch-axis bending beams, the bending strength of the cross-section of the arch bridge is significantly increased, the bending moment of the cross-section of the arch at the central bearing point is decreased, the vertical displacement at the haunch of the arch is lesser, and the deformation of the main girder is reduced, thus the force of the entire bridge is more reasonable, the construction cost can effectively be reduced and the construction period can be shortened.

摘要： In a load-bearing construction (1) having at least one load-bearing element (2), the load-bearing element (2) has at least one cavity (5) in which at least one rod (4) is disposed, the total cross-sectional area of all rods (4) each arranged in a cavity (5) being smaller than the cross-sectional area of this cavity (5), and the remaining volume of the cavity (5) being filled with a material (6). The rod (4) is displaceable along its length relative to the load-bearing element (2) when the load-bearing element (2) is deformed, the rod (4) being non-displaceably fixed at only one point relative to the load-bearing element (2) and being designed such that it dissipates energy upon the occurrence of a relative displacement with respect to the load-bearing element (2).

摘要： Composite decks increase bridge strength and stiffness. Prestressed composite open web steel girder has added advantage of high strength cable support. Results of typical 125 m span bridges having heights of 9.0 m, 10.0 m and 12.5 m, and another 50.0 m span and 2.5 m height are given. Member stresses and bridge deflections during erection remained safe. Average steel off take for the 125 m bridge is 2.65 t/m and for the 50 m span bridge it is 1.77 t/m for limiting live load deflection of Span/800. Its reserve strength is 3.2 times service condition live load.
The girders are panel wise workshop fabricated, assembled at site, jacked up or crane lifted to secure over bearings. Connection of the cross members, and onsite deck casting in parts with stage wise bottom chord prestressing is carried out. Short to long span bridges for single or multiple lanes in road, rail, metro rail, and coastal link projects are feasible.

摘要： A long span truss of substantially conventional steel construction provided with concrete encasement of the top and bottom chords with the concrete encasement being reinforced and the concrete encasement on the bottom chord and optionally on the top cord including post-tensioned steel tendons. The invention further relates to a method of making the truss as described above in which the light structural steel truss is first erected and provided with temporary steel scaffolding and bracing to support formwork. Reinforcing steel and steel tendons are placed in the formwork and concrete is poured to encase the top and bottom chords of the truss. The steel tendons are post-tensioned to provide maximum load support capability. The truss of the present invention can be used in situation where trusses are used to carry heavy loads over long spans such as bridges, stadiums, convention halls and the like and is especially beneficial when spanning a busy highway or waterway with the trusses including a single span or continuous trusses of two or more spans in which one or more intermediate supports are employed.

摘要： A method of post-tensioning a truss of substantially conventional steel construction provided with concrete encasement or cladding of certain chords while the truss is in a fabrication yard or at ground level before erection and installation in which the structural steel truss is first assembled in a fabrication yard with certain of the chords being provided with formwork. Reinforcing steel and steel tendons are placed in the formwork and concrete is poured to encase the chords of the truss while the truss is positioned horizontally or vertically in the fabrication yard or at ground level. The steel tendons are then partially or fully post-tensioned to provide maximum load support capability. The cladded and partially or fully post-tensioned truss is then lifted to an installation point and a load deck placed on the truss with final post tensioning of the truss then being completed. The truss of the present invention can be used in situations where trusses are used to carry heavy loads over long spans such as bridges, stadiums, convention halls and the like and is especially beneficial when spanning a busy highway or waterway since the trusses are assembled, cladded with concrete and partially post-tensioned before being lifted and placed in an installation site.
