Intensity of load on road bridges in a congestion situation
Abstrak
Abstract: The work analyzed the safety of road bridges during their exploitation in the situation of maximum load. Such bridge loads occur during acceptance tests of the object when the system of cars on the roadway is programmed. Considered in the work is the situation of full load on bridges occurring during a road congestion. Then the layout of the vehicles is inherently random and several of them can form a system of maximum, local load. The results of measurements during the actual congestion created on the bridge with a suspended diagram were related to the results of numerical analyzes. A two-beam span model and a dual carriageway load system in the congestion were adopted. As an extreme case, the load from two vehicles was considered at work, but in a small bridge. A replacement load algorithm was used for comparative analysis. Keywords: Safety of road bridge, Congestion, Numerical analysis
