Description
Long fjord-crossing floating bridges are critical infrastructure for road connections between land areas separated by wide and deep fjords. Such structures are subjected to complex environmental conditions while also meeting continuous traffic demand. This paper presents a numerical framework for evaluating the global response of a long floating bridge under combined traffic and wave actions. The proposed framework combines microscopic traffic-flow simulation, moving-load conversion and time-domain response analysis. Different traffic states, including free-flow, capacity and congestion traffic conditions, are considered. The framework is demonstrated using a floating bridge concept for the Bjørnafjord crossing. The case study shows that the proposed framework can represent different traffic-load processes and evaluate the corresponding bridge responses under combined stochastic traffic and wave actions. The study demonstrates the feasibility of the framework for future response assessment of long floating bridges subjected to simultaneous environmental and traffic loads.o simultaneous environmental and traffic loads.
