Structural Design of Newly Developed Temporary Footbridge

Abstract:

The paper deals with the design of steel structure of the temporary footbridge, intended especially for the usage in the construction site for pedestrian and bicycle traffic. In the period of last two years, on the authors workplace, in the co-operation with the mounting company, the new type of steel footbridge is being developed. Within this development the attention is, among others, paid to the structural design, in particular to the harmonization of static solution and structural detailing, to achieve the efficient design. In the course of solving this problem, two types of the footbridge are being developed in parallel. Both footbridges are composed as the structures with a lower deck, truss main girders and bracings; the first structure (short footbridge) with a small self-weight may have the span up to 18 m; the second structure (long footbridge) with a normal self-weight may have the span up to 36 m. The paper is focused on the brief description of structural composition and parameters of the short footbridge, as well as structural detailing of the joints of main load-carrying parts. The configuration of the whole structure and individual structural details have been designed with respect to the static, dynamic and fatigue affects, which have been experimentally verified using loading tests of the footbridge prototype with the span of 18 m and fatigue tests of significant structural details.
