Abstract

The design parameters, central beam high-span ratio, high-span ratio at root of the beam and beam bottom parabola, on continuous rigid frame bridge girder were valued in an appropriate range. Based on orthogonal experiment and numerical simulation, the effects of above parameters to the comprehensive performance index on the basis of stress, deflection and concrete volume were studied by the parameters combinations and the calculation of the text models. The research shows that the central beam high-span ratio has the greatest impact on the comprehensive performance Index, the beam bottom parabola have less influence when the high-span ratio at root of the beam. Especially, the impact of the beam bottom parabola is larger than the high-span ratio at root of the beam.
