This data article provides a series of 220 optimal parameter sets steel radial network arch pedestrian bridge schemes. Each set includes 10 design parameters for two-dimensional frame: the rise, number hangers, their (variable) spread and central angles, dimensions arch, girder, hangers. Additionally, solutions are provided different initial conditions such as constant hanger given ratio values between rise span, diameters, condition hangers' verticality. These related to research "Parametric study on mass minimization bridges" (Belevičius et al., 2021). In this paper, scheme was optimized seeking minimal under loading cases according recommendations Eurocode EN 1991-2. Since optimization problem is multimodal, employed stochastic global algorithms provide each run algorithm, we render five best parameters' every problem. many cases, close objective function correspond fairly distinct values. dataset could be used by designers an hint choosing appropriate set.
