| Abstrakt: | The architecture of footbridge design takes the form of a number of submissions from leading architects and engineers, each setting out their views on bridge design - present and future. It looks at the functions of a bridge, defining purpose of place and context, the spirit of creativity and the reasoned progression of an idea. It also explores the exploitation of materials technology and construction innovation, and the tension between lightness and mass and between sculpture and scale. With the progress of ever-increasing span of footbridges and the application of modern light and high strength materials, as well as the pursuit of bridge esthetic in urban areas, the fundamental frequency of modern flexible footbridges decreases significantly. Present parameters of tempered and laminated glass create possibility of modern architecture of footbridges which are being full of transparency and light reflex effects. Four projects, using glass panels designed by Santiago Calatrava have been presented in paper. Glass Fiber Retrofit Polymer makes new horizon in material technology, helps to rich new conception of structure with longer durability, low weight of deck, new creation of architecture line. The paper has described a few results of FEM analysis of footbridge with modular bridge GFRP deck system. Composite material consists of glass fibers and polymer matrix is promising alternative against traditional materials. New architecture, modern material engineering are looking for fresh possibilities of form and shape of structure, long durability and extraordinary technical parameters of building elements. Modern glass and GFRP are suitable for present and future applications in footbridges. Nowadays footbridges are a playground for sculpture-like structures. |
