Load combinations for design. 1 Determination of snow loads 5. Keyword-suggest-tool. A typical example of a set of load combinations is given below, which accounts for the fact that the dead load, live load and wind load are all unlikely to act on the structure simultaneously at their maximum values: (Stress due to dead load + live load) < allowable stress (Stress due to dead load + wind load) < allowable stress. Therefore, these models are artificial models and not necessarily real vehicles. All possible combinations of specified load cases are generated. Preliminary analysis and com-parison of traffic load effects determined according to SNiP and first pre-standards ENpr at that time showed that the Eurocode loads for existing highway bridges are heaver sometimes up to 1,5-2 times (Notkus 1998, 2005). Eurocode load combinations work in a different way: combination 1 no longer exists. Combinations of loads that have been factored are evaluated for maximum loads, moments or stresses. Eurocode Example Load Combinations - Free download as PDF File (.
