ABSTRACT

Nowadays footbridges designs underline the significance of the architectural form. However, the use of complex forms is sometimes strictly limited by the geometry of elements. The search for more complicated and slender forms significantly increases the costs of raising the structure. Based on the calculations of 300 modeled structures gathered in a database, function for determining the mass of steel of designed structures was established. Research shows that there is a simple correlation between basic dimensions and mass of structure in evaluated footbridges. Based on the shape of the structure and using the golden ratio, it is possible to establish aesthetic criteria useful for aesthetic optimization of the structure. This formula can be helpful for designers during conceptual level of design. Presented research is a pilot study on this subject and will be further developed in the future.
