Structural Design and Artistic Expression of Landscape Multi-Span Arch Footbridge

Abstract

In order to perfectly make the bridge function, structural style, architectural art modeling with the surrounding environment, this paper, based on the design of landscape five-span arch footbridge, studies the span arrangement, structural style, building materials, railing shape, ornament style and color, and lamplight illumination of the bridge considering the factors such as hydrology, geology, surrounding environment (e.g. buildings and park), traffic flow and entire urban planning. To reduce the stress of main arch and the horizontal thrust of substructure, the new structure of T-frame with sloped plate was put forward to bear the deck loads with the assistance of main plate arch. The thin concrete walls were cast on the top sides of the main plate arch, which were decorated by fine stone with the modern decoration construction technology. The white marble railings present lively morphology with carved lotus and pomegranate on the column cap, and many kinds of flowers on the panels. The spotlights make dramatic night sense for the bridge. Therefore, the landscape footbridge in the classical arch graceful shape was constructed by the modern building material and the optimized reinforced concrete structure, which presents the unity and coordination of structural design and artistic expression.
