Antisymmetric beam-arch combined structure footbridge

Abstract

The invention discloses an antisymmetric beam-arch combined structure footbridge. The antisymmetric beam-arch combined structure footbridge comprises a first arch bridge part and a second arch bridgepart which are arranged in an antisymmetric mode. Each of the first arch bridge part and the second arch bridge part comprises a bearing platform, a semi-arch ring, a conversion platform, a longitudinal beam, an inclined strut combination and a plurality of pile foundations, the bearing platform is fixed on the plurality of pile foundations, and two ends of the semi-arch ring are respectively fixed on the bearing platform and the conversion platform, wherein the two ends of the longitudinal beam are fixedly connected with the inclined strut combination and the conversion platform respectively,the inclined strut combination is fixed on the bearing platform, the conversion platform of the first arch bridge part is fixedly connected with the conversion platform of the second arch bridge part, and the half arch ring is provided with a stairway. Advantages of two structural forms of beams and arches are taken, a novel antisymmetric arched beam system is combined through a geometrical relationship, and an arch ring and the ground are connected to arrange a stairway to serve as a pedestrian passage. The structure has the advantages of being reasonable in stress, high in bearing capacity,small in deflection, safe, applicable, economical, attractive, free of redundant structures, attractive in line type and simple in appearance.

Description

technical field [0001] The invention belongs to the technical field of bridges, in particular to a pedestrian bridge with an antisymmetric beam-arch composite structure. Background technique [0002] With the rapid development of social economy and the acceleration of urbanization in my country, people's requirements for improving the living environment are getting higher and higher. Bridge landscape design occupies an extremely important position in urban landscape design, and plays a significant role in improving the livable environment of the city. The landscape and viewing functions of bridges have attracted more and more attention. very important position. At present, there are some misunderstandings in bridge landscape design: one is that bridge design is too pursuit of cost saving and convenient construction, resulting in too single bridge style, unable to meet the needs of urban landscape; The landscape design is out of touch with the force of the bridge structure,...
